-      copyright notice that is included in or attached to the work
-      (an example is provided in the Appendix below).
-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain

-      Work and such Derivative Works in Source or Object form.
-
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,

-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,
-      where such license applies only to those patent claims licensable
-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
-
-   END OF TERMS AND CONDITIONS
-
-   APPENDIX: How to apply the Apache License to your work.

-      To apply the Apache License to your work, attach the following
-      boilerplate notice, with the fields enclosed by brackets "[]"

-## Skill-bundle plugins
-
-When a plugin's source repository ships skills (`SKILL.md` files) without a `.claude-plugin/plugin.json` manifest, the marketplace entry can declare the skills directly using `strict: false` and an explicit `skills` array.
-
-```json
-{
-  "name": "example-bundle",
-  "description": "Brief description of the bundled skills.",
-  "author": { "name": "Author Name" },
-  "category": "development",
-  "source": {
-    "source": "git-subdir",
-    "url": "https://github.com/example-org/sdk.git",
-    "path": "packages/agent-skills",
-    "ref": "main",
-    "sha": "<commit sha>"
-  },
-  "strict": false,
-  "skills": [
-    "./skill-a",
-    "./skill-b",
-    "./skill-c"
-  ],
-  "homepage": "https://github.com/example-org/sdk"
-}
-```
-
-Each path in `skills` is relative to `source.path` and points at a directory containing a `SKILL.md`. Paths can reach deeper than a single level — for example, `["./libA/skill-1", "./libB/skill-2"]` exposes a curated subset across multiple library subdirectories. Each skill is registered as `<plugin-name>:<skill-name>` in Claude Code.
-
-For the underlying schema, see [Strict mode](https://code.claude.com/docs/en/plugin-marketplaces) in the marketplace documentation.

 **Value**: Claude can query tables, manage auth, and interact with Supabase storage directly.

-**Best for**: Projects using Convex as the backend (reactive database + server functions + auth + storage + scheduling, all on one platform)
-
-| Recommend When | Examples |
-|----------------|----------|
-| Convex project detected | `convex` in deps, `convex/` directory present, `convex.json` at repo root |
-| Real-time / reactive UI | `useQuery` / `useMutation` / `useAction` from `convex/react` |

-| AI / chat / agent features on Convex | `@convex-dev/agent` in deps |
-
-**Value**: Claude can introspect the live deployment (tables, function specs, env vars, logs) and execute queries/mutations against it via tools like `tables`, `function-spec`, `data`, `run-once-query`, `logs`, `env list/set/get`. Run via `npx convex mcp start`.

-# mcp-tunnels
-
-Connect Claude to an MCP server running inside your private network through an
-Anthropic [**MCP tunnel**](https://platform.claude.com/docs/en/agents-and-tools/mcp-tunnels/overview)
-— no inbound ports, no public exposure, no IP allowlisting on your origin.
-Traffic flows over an outbound-only connection.
-
-> **Research preview.** MCP tunnels is provided "as-is" with no uptime or
-> support commitment and depends on a third-party transport provider
-> (Cloudflare). Review the
-> [security model](https://platform.claude.com/docs/en/agents-and-tools/mcp-tunnels/security)
-> before sending anything sensitive.
-
-## Commands
-
-### `/create-docker-mcp-tunnel [deployment-dir]`
-
-Drives the MCP tunnels
-[**quickstart**](https://platform.claude.com/docs/en/agents-and-tools/mcp-tunnels/quickstart)
-end to end on your machine, using Docker
-Compose with manually supplied credentials (the shortest path for local
-testing). It walks you through the parts only you can do in the Claude Console
-and runs everything else for you:
-
-1. **Preflight** — checks Docker, Docker Compose, OpenSSL, and outbound
-   connectivity.
-2. **Create the tunnel** (Console) — you create it and copy the domain; the
-   token stays out of the chat and goes into a locked-down, gitignored `.env`.
-3. **Certificates** — generates a CA and a server certificate with OpenSSL,
-   with the exact extensions the tunnel requires.
-4. **Register the CA** (Console) — you upload `ca.crt`; the tunnel goes Active.
-5. **Upstream** — scaffolds a verifiable FastMCP sample server, or wires up an
-   MCP server you already have.
-6. **Proxy config + Compose** — writes `mcp-proxy.yaml` and a
-   `docker-compose.yaml` with digest-pinned images and the cloudflared agent.
-7. **Start and verify** — brings the stack up and checks the proxy and tunnel
-   logs.
-8. **Call it from Claude** — shows you how to reach the server from Managed
-   Agents and the Messages API.
-
-It also carries a troubleshooting matrix (TLS handshake failures, the
-`routes`-must-be-a-map gotcha, the `tls.key` permission issue, the
-config-is-not-hot-reloaded trap, upstream IP validation) and the operational
-basics for token rotation and certificate renewal.
-
-**Usage:**
-
-```
-/create-docker-mcp-tunnel
-/create-docker-mcp-tunnel ~/work/my-tunnel
-```
-
-### Copying the CA certificate to another machine
-
-You register the CA in the Console from a browser, which is often a different
-machine than the one running the stack (for example, the tunnel runs in a
-remote homespace but you upload `ca.crt` from your laptop or devbox). Only the
-**certificate** (`<deployment-dir>/data/ca.crt`, ~1 KB PEM) leaves the host —
-never `data/ca.key` or `data/tls.key`.
-
-For a file this small, the simplest path is to print it and paste it into the
-Console's certificate field directly:
-
-```bash
-cat <deployment-dir>/data/ca.crt   # default: ~/mcp-tunnel/data/ca.crt
-```
-
-To copy it as a file with `scp`, run the command from whichever machine can
-SSH to the other (`scp` can't relay between two remotes). Pulling from a
-homespace onto your devbox — if you've run `coder config-ssh`, the host is
-`coder.<workspace>`:
-
-```bash
-scp coder.<workspace>:<deployment-dir>/data/ca.crt .
-# generic form: scp <homespace-ssh-host>:~/mcp-tunnel/data/ca.crt .
-```
-
-Or push from the host to the devbox, if the host can reach it:
-
-```bash
-scp <deployment-dir>/data/ca.crt <user>@<devbox-host>:~/
-```
-
-## What gets built
-
-A small container stack on your host:
-
-| Container | Role |
-|---|---|
-| **mcp-proxy** | Anthropic's proxy. Terminates inner TLS with a cert you control, validates upstream IPs, routes by hostname. |
-| **cloudflared** | The tunnel agent. Outbound-only to the Anthropic tunnel edge; shares the proxy's network namespace. |
-| **hello-mcp** *(optional)* | A FastMCP sample server, only if you don't have an MCP server to expose yet. |
-
-When it's running, the routed server is reachable from Claude at
-`https://<subdomain>.<your-tunnel-domain>/<path>` with nothing listening on a
-public port.
-
-## Requirements
-
- Docker and Docker Compose.
- OpenSSL 1.1.1 or newer.
- A Claude Console role that can manage MCP tunnels.
- Outbound access to `api.anthropic.com:443` and the tunnel edge on 7844
-  TCP/UDP. No inbound ports are opened.
-
-## Scope and next steps
-
-This plugin targets the **manual-credentials, single-host, local-testing**
-path. For a hardened single-host deployment (non-root, read-only rootfs,
-dropped capabilities), a Kubernetes deployment, or programmatic access via
-[Workload Identity Federation](https://platform.claude.com/docs/en/manage-claude/workload-identity-federation),
-see the official deployment guides:
-[Deploy with Docker Compose](https://platform.claude.com/docs/en/agents-and-tools/mcp-tunnels/deploy-compose) /
-[Deploy with Helm](https://platform.claude.com/docs/en/agents-and-tools/mcp-tunnels/deploy-helm).

-Be a careful operator: explain each step briefly, run the commands, check the
-output, and stop with a clear diagnosis if something fails.
-
-Deployment directory: use `$ARGUMENTS` if the user passed a path, otherwise
-default to `./mcp-tunnel`. Refer to it below as `$DIR`.
-
-## What you'll build
-
-A container stack on the user's machine:
-
- **mcp-proxy** — Anthropic's proxy. Terminates the inner TLS handshake using
-  a certificate the user controls, validates upstream IPs, routes by hostname.
- **cloudflared** — the tunnel agent. Outbound-only connection to the Anthropic
-  tunnel edge; shares the proxy's network namespace.
- **hello-mcp** *(optional)* — a sample FastMCP server, only if the user has no
-  MCP server of their own to expose yet.
-
-When it's up, the routed server is reachable from Claude at
-`https://<subdomain>.<tunnel-domain>/<path>` with nothing listening on a public
-port.
-
-## Step 0 — Preflight
-
-Run these and report what's missing before going further:
-
-```bash
-docker --version && docker compose version && openssl version
-```
-
- Docker + Docker Compose are required. `openssl` 1.1.1+ is required (the
-  commands below use `-addext`, available in 1.1.1+).
- Confirm the host has **outbound** access to `api.anthropic.com:443` and the
-  tunnel edge (`198.41.192.0/19`, `2606:4700:a0::/44`) on **7844 TCP and UDP**.
-  No inbound ports are opened.
-
-If `docker compose` (v2) is unavailable but `docker-compose` (v1) exists, use
-that and tell the user; the compose file is v2-compatible.
-
-## Step 1 — Create the tunnel (Console — user action)
-
-Tell the user to do this in the [Claude Console](https://console.anthropic.com)
-(see [Create a tunnel](https://platform.claude.com/docs/en/agents-and-tools/mcp-tunnels/console#create-a-tunnel)):
-
-1. Sidebar → **Manage → MCP tunnels** → **New tunnel**. Give it a name.
-2. Leave **Set up programmatic access** **off** — this quickstart uses manual
-   credentials.
-3. Open the tunnel. From the **Connection** section copy two values:
-   - **Domain** — looks like `abcd1234.tunnel.anthropic.com`
-   - **Token** — click the eye icon, then copy
-
-Then ask the user, via AskUserQuestion or a direct prompt, for the **Domain**.
-**Do not ask them to paste the Token into the chat.** The token is a secret
-that authenticates the outbound tunnel connection; keep it out of the
-transcript. Instead, tell them you will create a `$DIR/.env` file and they
-should paste the token into it themselves (Step 3), or have them export it:
-`export TUNNEL_TOKEN='eyJ...'` in the shell you'll run compose from.
-
-Record the domain as `TUNNEL_DOMAIN` for the steps below.
-
-## Step 2 — Deployment directory
-
-```bash
-mkdir -p "$DIR"/{config,data}
-cd "$DIR"
-```
-
-## Step 3 — Credentials file
-
-Create `$DIR/.env` (compose auto-loads it; this survives reboots, unlike a
-shell `export`). Write `TUNNEL_DOMAIN` yourself; leave a placeholder for the
-secret and have the **user** fill it in:
-
-```
-TUNNEL_DOMAIN=<the domain from step 1>
-TUNNEL_TOKEN=PASTE_TUNNEL_TOKEN_HERE
-```
-
-Then lock it down and make sure it never gets committed:
-
-```bash
-chmod 600 "$DIR/.env"
-printf '.env\ndata/\n' > "$DIR/.gitignore"
-```
-
-Pause and have the user replace `PASTE_TUNNEL_TOKEN_HERE` with the real token
-(tell them the exact file path). Verify it's set without printing it:
-
-```bash
-cd "$DIR" && grep -q '^TUNNEL_TOKEN=eyJ' .env && echo "token looks set" || echo "token NOT set — edit .env"
-```
-
-Load it for the openssl/config steps in this shell:
-
-```bash
-cd "$DIR" && set -a && . ./.env && set +a && echo "domain: $TUNNEL_DOMAIN"
-```
-
-## Step 4 — Generate the CA and server certificate
-
-The proxy terminates an inner TLS handshake using a certificate signed by a CA
-the user controls. Generate both (Linux/macOS shown; the
-[quickstart](https://platform.claude.com/docs/en/agents-and-tools/mcp-tunnels/quickstart)
-also has a Windows PowerShell variant — offer it if the user is on Windows):
-
-```bash
-cd "$DIR"
-
-openssl req -x509 -newkey rsa:2048 -nodes \
-  -keyout data/ca.key -out data/ca.crt \
-  -days 3650 -subj "/CN=mcp-tunnel-ca" \
-  -addext "basicConstraints=critical,CA:TRUE" \
-  -addext "keyUsage=critical,keyCertSign,cRLSign" \
-  -addext "subjectKeyIdentifier=hash"

-
-Why these flags: the explicit `-addext` extensions make the CA satisfy the
-tunnel's [certificate requirements](https://platform.claude.com/docs/en/agents-and-tools/mcp-tunnels/reference#certificate-requirements)
-regardless of distro `openssl.cnf` defaults;
-`-extfile` (not `-copy_extensions`, which is OpenSSL 3.0+ only) keeps this
-working on OpenSSL 1.1.x and adds the `AuthorityKeyIdentifier` the proxy
-requires. `chmod 644 data/tls.key` is **required**: openssl writes the key
-`0600` but the proxy container runs as a non-root user and must read it.
-
-`data/tls.key` and `data/ca.key` are sensitive — they live under `data/`,
-which the `.gitignore` from Step 3 already excludes.
-
-## Step 5 — Register the CA (Console — user action)
-
-Have the user, on the tunnel detail page, scroll to **Certificates** →
-**Add certificate**
-(see [Add a CA certificate](https://platform.claude.com/docs/en/agents-and-tools/mcp-tunnels/console#add-a-ca-certificate)),
-and upload `$DIR/data/ca.crt` (or paste its contents —
-print it with `cat data/ca.crt` so they can copy it). The tunnel status flips
-to **Active** once a certificate is registered. The tunnel will not appear in
-the agent picker until this is done.
-
-Wait for the user to confirm the tunnel shows **Active** before continuing.
-
-## Step 6 — Choose the upstream MCP server
-
-Ask the user (AskUserQuestion):
-
- **"I have an MCP server already"** — get its reachable address as
-  `scheme://host:port` (port mandatory, no path — the proxy rejects a path in
-  the upstream value at config load). It must be reachable from the proxy
-  container and resolve to an RFC1918 private address (`10/8`, `172.16/12`,
-  `192.168/16`); the proxy refuses public/loopback upstreams by default
-  (SSRF protection). If it runs as a Compose service, add it to the compose
-  file so it shares the network. If it runs on the host, see Troubleshooting
-  ("host process"). Pick a route subdomain with the user (e.g. `wiki`).
- **"Use the sample server"** — scaffold the FastMCP `hello-server` below as a
-  Compose service `hello-mcp` and route subdomain `echo`.
-
-### Sample server (only if chosen)
-
-Write `$DIR/hello_server.py`:
-
-```python
-from mcp.server.fastmcp import FastMCP
-
-mcp = FastMCP("hello-server", host="0.0.0.0", port=9000)
-
-
-@mcp.tool()
-def hello(name: str = "world") -> str:
-    """Say hello to someone."""
-    return f"Hello, {name}!"
-
-
-if __name__ == "__main__":
-    mcp.run(transport="streamable-http")
-```
-
-## Step 7 — Proxy config
-
-Write `$DIR/config/mcp-proxy.yaml`. `tunnel_domain` is **required** (the
-proxy strips it from the incoming hostname to find the subdomain in `routes`).
-`routes` is a **flat map** subdomain → upstream URL, *not* a list:
-
-```yaml
-listen_addr: ":8080"
-log_level: info
-tunnel_domain: <TUNNEL_DOMAIN>
-tls:
-  cert_file: /data/tls.crt
-  key_file: /data/tls.key
-routes:
-  echo: http://hello-mcp:9000
-```
-
-Substitute the real `TUNNEL_DOMAIN`. Replace the `routes:` block with the
-user's chosen subdomain → upstream if they brought their own server (e.g.
-`wiki: http://wiki-mcp.internal:8080`). You can keep multiple routes.
-
-## Step 8 — Compose file
-
-Write `$DIR/docker-compose.yaml`. Images are pinned by digest:
-
-```yaml
-services:
-  mcp-proxy:
-    image: us-docker.pkg.dev/anthropic-public-registry/images/mcp-proxy@sha256:6b9adedbf2763143ec72f106ecaf0ce7fd3294e89b208f54a1db97a33d14c5ba
-    command: ["-config", "/etc/mcp-proxy/config.yaml"]
-    volumes:
-      - ./config/mcp-proxy.yaml:/etc/mcp-proxy/config.yaml:ro
-      - ./data:/data:ro
-    restart: unless-stopped
-
-  cloudflared:
-    image: cloudflare/cloudflared@sha256:6b599ca3e974349ead3286d178da61d291961182ec3fe9c505e1dd02c8ac31b0
-    command: tunnel --no-autoupdate run --url http://localhost:8080
-    environment:
-      - TUNNEL_TOKEN
-    network_mode: "service:mcp-proxy"
-    restart: unless-stopped
-```
-
-`--url http://localhost:8080` is **required** in the manual flow: no ingress
-rules are pushed server-side, so without it cloudflared 503s every request.
-`network_mode: "service:mcp-proxy"` shares the proxy's netns so
-`localhost:8080` reaches it. `environment: - TUNNEL_TOKEN` (no value) passes
-the variable through from `.env`.
-
-If the sample server was chosen, append the service:
-
-```yaml
-  hello-mcp:
-    image: python:3.13-slim
-    working_dir: /app
-    volumes:
-      - ./hello_server.py:/app/hello_server.py:ro
-    command: sh -c "pip install --quiet mcp && python hello_server.py"
-    restart: unless-stopped
-```
-
-If the user brought their own server *and* it's containerized, add its service
-here too so it shares the Compose network with the proxy.
-
-(For a hardened single-host deployment — non-root user, read-only rootfs,
-`cap_drop: ALL`, `no-new-privileges` — point the user at
-[Deploy with Docker Compose](https://platform.claude.com/docs/en/agents-and-tools/mcp-tunnels/deploy-compose);
-this quickstart keeps it minimal for fast local testing.)
-
-## Step 9 — Start and verify
-
-```bash
-cd "$DIR" && docker compose up -d
-sleep 5
-docker compose logs mcp-proxy | grep -i "route configured"
-docker compose logs cloudflared | grep -i "Registered tunnel connection"
-```
-
-Expect one `route configured` line per route and **four**
-`Registered tunnel connection` lines. Containers take a few seconds; rerun the
-log greps if they come back empty (don't conclude failure on the first empty
-result). If they stay empty, go to Troubleshooting.
-
-## Step 10 — Call it from Claude
-
-Tell the user both options:
-
-**Managed Agents (Console):** **Managed Agents → Sessions** → new session →
-agent picker **Create new agent** → **+ MCP Server** → select the tunnel →
-**Subdomain** = the route (`echo`), **Path** = `mcp` (FastMCP
-`streamable-http` serves at `/mcp`). Then ask: *"Use the hello tool to greet
-tunnel."* — expect a tool call and its result.
-
-**Messages API:** the host is `<subdomain>.<tunnel-domain>`; the path is
-whatever the upstream serves (`/mcp` for FastMCP). Use an API key for the
-workspace the tunnel was created in.
-
-```bash
-curl https://api.anthropic.com/v1/messages \
-  -H "Content-Type: application/json" \
-  -H "x-api-key: $ANTHROPIC_API_KEY" \
-  -H "anthropic-version: 2023-06-01" \
-  -H "anthropic-beta: mcp-client-2025-11-20" \
-  -d "{
-    \"model\": \"claude-opus-4-7\",
-    \"max_tokens\": 1024,
-    \"mcp_servers\": [{\"type\": \"url\", \"name\": \"echo\", \"url\": \"https://echo.${TUNNEL_DOMAIN}/mcp\"}],
-    \"tools\": [{\"type\": \"mcp_toolset\", \"mcp_server_name\": \"echo\"}],
-    \"messages\": [{\"role\": \"user\", \"content\": \"call hello with name=tunnel\"}]
-  }"
-```
-
-The tunnel carries encrypted traffic but does **not** authenticate to the
-upstream. If the upstream MCP server requires its own auth, the user supplies
-it the same as for any other MCP server.
-
-## Troubleshooting (diagnose in this order)
-
-| Symptom | Cause | Fix |
-|---|---|---|
-| Caller sees HTTP 500; cloudflared logs `No ingress rules were defined` | cloudflared has no local target | Ensure `--url http://localhost:8080` and `network_mode: "service:mcp-proxy"` are both present, then `docker compose up -d` |
-| Proxy exits `cannot unmarshal !!seq into map[string]string` | `routes` written as a YAML list | Use `routes: { name: http://host:port }`, not a list of objects |
-| Proxy exits `open /data/tls.key: permission denied` | key is `0600`, proxy runs non-root | `chmod 644 data/tls.key` |
-| Proxy logs `no route for host` (caller gets `502 No route configured for host`) | `tunnel_domain` missing or wrong | Set it to the exact domain on the tunnel detail page; then **restart the proxy** (next row) |
-| Edited config but nothing changed | proxy does **not** hot-reload `config.yaml` (only `tls.cert_file`) | `docker compose restart mcp-proxy` — `up -d` alone won't recreate it on a file-content change |
-| `tls handshake failed ... unknown certificate authority` | CA not registered/revoked on this tunnel | Re-upload `data/ca.crt` in the Console (Step 5) |
-| `tls handshake failed ... bad certificate` | server cert SAN ≠ `*.<tunnel-domain>`, or expired | Regenerate the server cert (Step 4) with the correct `TUNNEL_DOMAIN` |
-| `IP validation failed: <ip> is not a private address` | upstream resolves outside RFC1918 (e.g. `127.0.0.1`, public IP) | Run the upstream as a Compose service on the proxy's network; or narrow `upstream.allowed_ips` deliberately (avoid `0.0.0.0/0` outside local testing) |
-| `dial tcp ...: connect: connection refused` for `host.docker.internal` | rootless Docker can't reach the host netns | Run the MCP server as a Compose service instead of a host process |
-| HTTP 502, no `request started` in proxy log | cloudflared hadn't finished registering, or rolling update | Wait for ×4 `Registered tunnel connection` and retry |
-| Tunnel missing from agent **+ MCP Server** picker | no active certificate, or wrong workspace | Register a CA cert (Step 5); open the session in the tunnel's workspace |
-| `curl https://<proxy>:8080` fails `wrong version number` | expected — listener is plaintext WS, TLS is inside the WS stream | Don't curl the proxy directly; verify via Managed Agent or Messages API |
-
-`docker compose logs cloudflared` (token/edge reachability) and
-`docker compose logs mcp-proxy` (config/cert/routing) are the two primary
-diagnostics. Check the outbound connection first, then the inner TLS handshake,
-then upstream routing. See
-[Troubleshooting](https://platform.claude.com/docs/en/agents-and-tools/mcp-tunnels/troubleshooting)
-for additional cases.
-
-## Operational notes (mention briefly, don't run unprompted)
-
- **Token rotation:** Console → **Rotate token** invalidates the old token
-  immediately. Update `TUNNEL_TOKEN` in `.env` and
-  `docker compose up -d cloudflared`.
- **Cert renewal:** the server cert is valid 90 days. Re-sign with the same CA
-  (the registered CA doesn't change) and replace `data/tls.crt`; the proxy
-  polls and reloads it, no restart needed.
- **Config changes always need** `docker compose restart mcp-proxy`.
-
-## Wrap up
-
-Summarize: deployment dir, route(s) configured, tunnel domain, and the exact
-URL Claude reaches the server at. Remind the user the token is a live secret in
-`$DIR/.env` (chmod 600, gitignored) and that this is a research-preview,
-local-testing setup — point them at
-[Deploy with Docker Compose](https://platform.claude.com/docs/en/agents-and-tools/mcp-tunnels/deploy-compose) /
-[Deploy with Helm](https://platform.claude.com/docs/en/agents-and-tools/mcp-tunnels/deploy-helm)
-for a hardened or programmatic-access deployment.

-# security-guidance
-
-Security review for Claude-generated code. Three layers:
-
-1. **Pattern warnings** — instant regex-based reminders on `Edit`/`Write` for ~25 known-dangerous patterns (`yaml.load`, `torch.load(weights_only=False)`, `pickle.load` on untrusted data, raw `innerHTML`, hardcoded secrets, etc.).
-2. **LLM diff review** — when Claude finishes a turn, the plugin sends the diff to a fast LLM call (Opus 4.7 by default) and feeds high-severity findings back to Claude so it can fix them before you see the response.
-3. **Agentic commit review** — on `git commit`, an SDK-driven reviewer reads related files (`Read`/`Grep`/`Glob`) to trace data flow across the codebase, catching multi-file vulnerabilities pattern matching misses (IDOR, auth bypass, cross-file SSRF).
-
-Findings cover common web-vulnerability classes — injection, XSS, SSRF, hardcoded secrets, IDOR, auth bypass, unsafe deserialization, and path traversal among others.
-
-## Install
-
-```
-/plugin install security-guidance@claude-plugins-official
-```
-
-Marketplace ships enabled by default in Claude Code — no setup beyond having the CLI itself.
-
-## Prerequisites
-
- Claude Code CLI ≥ v2.1.144
- Python 3.8+ on `PATH` (`python3`, `python`, or `py -3` — the plugin picks the first that works)
- A working API path (subscription, API key, or 3P provider config)
-
-## Configuration
-
-All configuration is via environment variables. None are required for default behavior.
-
-### Selecting a model
-
-```bash
-# 1P / gateway: a canonical model id
-SECURITY_REVIEW_MODEL=claude-opus-4-7   # default
-
-# Bedrock: use the inference-profile id
-SECURITY_REVIEW_MODEL=us.anthropic.claude-opus-4-7
-
-# Vertex: use the Vertex date-tag form
-SECURITY_REVIEW_MODEL=claude-opus-4-7@20260218
-```
-
-`SECURITY_REVIEW_MODEL` controls the LLM diff review. `SG_AGENTIC_MODEL` (same syntax) controls the agentic commit reviewer; defaults to the same model.
-
-### Enabling/disabling layers
-
-| Variable | Default | What it does |
-|---|---|---|
-| `SECURITY_GUIDANCE_DISABLE=1` | unset | Kill switch — disables the entire plugin |
-| `ENABLE_PATTERN_RULES=0` | on | Disable layer 1 (regex pattern warnings) |
-| `ENABLE_CODE_SECURITY_REVIEW=0` | on | Disable all LLM reviews (Stop hook + commit/push) |
-| `ENABLE_STOP_REVIEW=0` | on | Disable only the Stop-hook diff review, keeping commit/push reviews. Useful for multi-agent / shared-worktree setups where another agent can move HEAD between a worker's turns |
-| `ENABLE_COMMIT_REVIEW=0` | on | Disable layer 3 (agentic commit review) |
-
-### Higher-recall mode
-
-```bash
-SG_DUAL_OR=on   # default off
-```
-
-Runs two parallel review calls and unions the findings. Catches a few percentage points more vulnerabilities in our testing, at roughly 2× the API cost per review. Most users don't need it.
-
-## Org-specific policies
-
-Drop a `claude-security-guidance.md` in any of:
-
- `~/.claude/claude-security-guidance.md` — user-wide rules
- `<project>/.claude/claude-security-guidance.md` — project rules, intended to be committed
- `<project>/.claude/claude-security-guidance.local.md` — local overrides, intended to be `.gitignore`'d
-
-All three are loaded and concatenated into the LLM diff review's prompt in the order user → project → project-local. If the combined size exceeds the 8 KB prompt budget, the tail is truncated, so user-wide rules are kept and project-local rules are dropped first. The agentic commit reviewer (layer 3) does not currently read this file. Example:
-
-```markdown
-# Acme security rules
-
- All SELECTs against the `customers` or `orders` tables MUST go through `db.replica`,
-  never `db.primary`. Primary is for writes only.
- Background jobs must not use the user-context auth token; they get
-  service-account creds from `jobs.get_service_account()`.
- Calls to `requests.get(url)` with a user-controlled `url` need
-  the SSRF-allowlist wrapper at `acme.net.safe_request`.
-```
-
-Built-in rules cover common web-vulnerability classes without it — `claude-security-guidance.md` is for things specific to your codebase that the model can't infer.
-
-## Privacy and data handling
-
-The plugin sends data to a model endpoint to perform its reviews. Specifically, each Stop-hook diff review transmits the changed file paths, the diff hunks, and the relevant file contents in the diff; each agentic commit review additionally transmits any files the reviewer pulls in via `Read`/`Grep`/`Glob` while tracing data flow. Your `claude-security-guidance.md` contents (user, project, and local) are appended to the prompt on every review, so don't put secrets in it.
-
-Where that data goes depends on your Claude Code configuration:
- **Default (Anthropic API / subscription):** sent to `api.anthropic.com` and handled under Anthropic's [Commercial Terms](https://www.anthropic.com/legal/commercial-terms) and [Privacy Policy](https://www.anthropic.com/legal/privacy).
- **LLM gateway** (`ANTHROPIC_BASE_URL` set): sent to your gateway URL instead. The gateway operator's terms apply.
- **3rd-party providers** (Bedrock / Vertex / Foundry / Mantle): sent to your configured provider endpoint. The provider's data-handling terms apply (e.g., AWS / GCP / Azure).
-
-The plugin writes its own debug log to `~/.claude/security/log.txt` (override with `SECURITY_GUIDANCE_DEBUG_LOG`). The log contains diffstate metadata and finding categories — no full file contents or model prompts — and rotates at 1 MB. Nothing is uploaded.
-
-## Limitations
-
-This is a best-effort assistive tool, not a guarantee. Treat findings as suggestions, not as a substitute for human code review, SAST/DAST, dependency scanning, or pen-testing. The reviewer can miss vulnerabilities, produce false positives, and may behave differently across codebases, languages, and model versions. **No warranty is provided** — use is subject to Anthropic's [Commercial Terms](https://www.anthropic.com/legal/commercial-terms).
-
-## Troubleshooting
-
-**Plugin doesn't seem to fire** — check that `~/.claude/claude-security-guidance.md` (or hook activity) shows in debug logs. Run Claude Code with `--debug-file /tmp/claude/debug.txt` and grep for `security_reminder_hook`. The plugin also writes its own log to `~/.claude/security/log.txt`.
-
-**Review never finds anything** — verify your API path works. On 3P providers, check `SECURITY_REVIEW_MODEL` is set to a provider-specific id (not a bare `claude-opus-4-7`). On LLM gateways, check the gateway's logs for `POST /v1/messages` traffic from the plugin.
-
-**Too many false positives** — drop `SECURITY_REVIEW_MODEL` to a cheaper model (`claude-sonnet-4-6`) and re-evaluate; if precision is the priority, stay on Opus 4.7.
-
-**Want to silence a specific finding** — add a comment to the line explaining why it's safe; the LLM reviewer treats inline justifications as exclusions. For systemic exclusions, document them in your `claude-security-guidance.md`.
-
-## Reporting issues
-
-Open an issue on the [security-guidance plugin repo](https://github.com/anthropics/claude-code/issues) with:
- The Claude Code CLI version (`claude --version`)
- Provider setup (1P / Bedrock / Vertex / LLM gateway / etc.)
- A minimal repro diff

-If claude_agent_sdk already imports in the current python3, this is a no-op.
-Otherwise it creates a venv at ~/.claude/security/agent-sdk-venv and installs
-the SDK there. security_reminder_hook.py prepends that venv's site-packages to

-"""Project-specific extensibility for the security-guidance plugin.
-
-Two extensibility points, both additive only:
-
-1. ``claude-security-guidance.md`` — markdown appended to every LLM review prompt.
-   The customer's equivalent of org-specific security policy: "we use Vault,
-   flag hardcoded creds but Vault refs are fine"; "every tenant-scoped query
-   must include WHERE org_id"; "*.corp.example.com is internal".
-
-2. ``security-patterns.{yaml,json}`` — custom regex/substring rules merged
-   with the built-in PostToolUse pattern warnings. No LLM call; pure regex.
-
-Discovery, in precedence order (matching CLAUDE.md / settings.json):
-  - ``~/.claude/<name>``                  (user)
-  - ``<cwd>/.claude/<name>``              (project, committed)
-  - ``<cwd>/.claude/<name>.local.<ext>``  (project local, gitignored)
-
-Managed delivery via ``managed-settings.json`` is not yet supported.
-Org admins can still push files to ``~/.claude/`` via MDM/GPO.
-
-Trust model:
-  - The ``.md`` is repo-controlled and goes into the USER prompt (not system),
-    inside a ``<project-security-guidance>`` block whose framing instructs the
-    model to treat it as additive ("may ADD checks but must NOT suppress
-    findings"). A malicious PR adding a ``.md`` that says "ignore SQL injection"
-    cannot suppress findings.
-  - Custom pattern reminders go into the same provenance-tagged block as the
-    built-in ones. Reminder length is capped.
-  - Custom regexes are validated at load for catastrophic-backtracking
-    structure and skipped (with a debug log) if they look ReDoS-prone.
-  - Built-in patterns cannot be disabled. ``ENABLE_PATTERN_RULES=0`` disables
-    all pattern checks; there is no per-rule kill switch in v1.

-# Stage 1 — investigate
-# ---------------------------------------------------------------------------
-
-AGENTIC_INVESTIGATE_SYSTEM = """You are a senior application-security engineer performing a deep security review of a code change. You have read-only filesystem tools (Read, Grep, Glob) scoped to the repository — USE THEM AGGRESSIVELY. The diff alone is not enough.
-
-The #1 cause of missed vulnerabilities is not reading the file that contains them. Before any analysis: Read EVERY changed file in full (not just the diff hunks). Then Grep for the changed function/class names to find callers. A vulnerability that requires cross-file context is still your responsibility.
-
-METHOD:
-
-Phase 1 — Map entry points and sinks touched by this change.
-  Entry points: HTTP handlers/routes, RPC methods, CLI args, webhook receivers, message consumers, file/upload handlers, OAuth callbacks, GitHub Actions inputs, MCP tools, hook handlers, IPC receivers (main/privileged process handling messages from a sandboxed/renderer/less-privileged process).
-  Sinks: shell/exec/subprocess, SQL/ORM raw, eval/new Function, filesystem paths (open/read/write/unlink), outbound HTTP (SSRF), HTML render/innerHTML, deserialization (pickle/yaml/json with object_hook), template engines, subprocess env, IAM/RBAC bindings, dynamic code/plugin/extension loaders (any API that loads+executes code from a path), log/telemetry/metrics dimensions (only when value matches a PII shape — email, token, free-text field; NOT a static enum/type name), cache-control / Vary headers (cache poisoning), DDL that drops a constraint/FK/trigger (referential-integrity), response bodies/headers, prompts sent to LLMs.
-  For each changed file, Grep for the function/class names in the diff to find their callers and what data reaches them.
-
-Phase 2 — Trace data flow.
-  For every value that reaches a sink, determine whether it is attacker-influenceable. Read upstream: where does the variable come from? Is there validation/sanitization between source and sink? Check sibling handlers in the same file — if they enforce a check this one omits, the omission IS the finding. Cross-component flows (input enters in module A, dangerous operation in module B) are where the high-value findings live; follow them.
-  FOLLOW RETURNS: when a changed function builds a tainted value (command string, SQL, URL, path, template) and RETURNS it rather than executing locally, the sink is in a CALLER — Grep for the function name and read the call sites before deciding it's safe.
-  SIBLING-PATH GATE PARITY: when + lines add a guard/check/tenant-scope/visibility-filter/invalidation/cleanup to ONE branch, ONE handler, or ONE layer, enumerate ALL sibling branches, early-returns, error/except paths, and peer handlers in the same router/service that touch the same resource — report any that lack an equivalent gate. ONLY emit when (a) both the guarded path AND the sibling reach a state-changing or boundary-crossing sink, AND (b) the sibling's input is controllable by a different principal than the guard checks for. Skip if the file has a "generated / DO NOT EDIT" header or lives under generated/openapi/autogen.
-
-Phase 2b — Parser/validator differentials (a top miss category).
-  When the change adds or modifies parsing, validation, normalization, or matching logic (regexes, URL/path parsers, allowlists, content-type checks, decoders, AST/shell parsers), ask: does an input exist that the validator ACCEPTS but the downstream consumer interprets differently? Look for: unanchored/partial regexes; case/encoding/unicode normalization mismatches; URL parsers that disagree on userinfo/host/path; allowlists checked with substring/startswith; decoders that accept malformed input; quoting/escaping the parser strips but the consumer doesn't. The finding is the differential itself — name both sides.
-
-Phase 2c — High-miss patterns. Check ONLY against + lines in the diff — do NOT flag pre-existing code you read while exploring.
-  - SENSITIVE-TO-OBSERVABILITY: a + line emits to a log/trace/span/metric/exception-message sink. Trace EVERY field (including URLs, paths, error-object .message, f-string vars, **kwargs) to its source and flag credentials, PII, customer content, or model free-text reaching the sink — especially on error/except branches where happy-path redaction is bypassed and external-service error messages can echo URL-embedded secrets. Skip if: a sanitizer wraps the value at the call site; the log is gated by a debug/dev env flag; or the value is static request metadata (method/path/host).
-  - IaC OMITTED ARG: a + line instantiates a Terraform/Pulumi/CDK module and OMITS an optional security-relevant arg — read the module's variables and check whether the default is the secure value.
-  - CI/CD TRUST: + lines add or change a GitHub Actions trigger to workflow_dispatch / repository_dispatch / pull_request_target without a branches: filter, AND the job reads secrets or has write permissions.
-  - ALLOWLIST SEMANTIC ESCAPE: + lines add an entry to a safe-command/safe-endpoint/capability allowlist OR add a `||` disjunct to a permission matcher OR edit a validator that gates exec/eval/subprocess. Verify no allowed entry achieves a denied effect via its arguments, flags, abbreviations, side-channels (DNS, config-write, env), or scope mismatch vs. enforcement (e.g., allowlist matches argv[0] but consumer reads full argv).
-  - OVER-BROAD GRANT: when + lines add a principal/identity to a broad-scope permission (global/service-wide allowlist, standing admin role binding, reuse of another principal's credential), check whether the SAME changed file or its immediate module already exposes a narrower-scope mechanism for the same need (per-resource/per-RPC allowlist, break-glass/2PC role, dedicated principal). If it does, the broad grant is the finding. Do NOT flag if no narrower mechanism is visible in the changed files.
-  - STALE IDENTITY MAPPING: + lines change teardown/unregister of an identity primitive (hostname/DNS, IP, service route, lease, auth token, service-registry entry) where a window leaves it resolvable to the wrong tenant. NOT in-process data caches.
-  - CONTROL REGRESSION: when - lines DELETE a fail-closed validator (allowlist returning False by default, _is_safe_*, deny-by-default) and + lines replace it with a single condition, the replacement IS the finding.
-  - FAIL-OPEN STATE DRIFT: when a security decision reads parsed/cached/tracked/callback state, verify error, cancellation, TOCTOU, cache-skew, and unhandled-variant paths do not yield a default that skips enforcement — broad-except→pass, unwrap_or({}), missing-finally cleanup, ignored verifier params, or stale validator maps all fail open. The finding is the path where the fallback value is the allow outcome. Also: when + lines compare against a security threshold, check whether the EXACT boundary value yields the permissive branch; when an error path triggers retry/redelivery, check whether the retry can emit a decision that overrides a stricter first decision; when sync logic reads persisted state, check whether state surviving a data wipe causes destructive sync.
-  - SECURITY-REGISTRY FANOUT: when + lines add a new entity (field, enum value, credential type, alias, model variant, port, scope), Grep unchanged files for every security registry keyed on that entity class — sanitizer field-lists, redaction sets, revocation handlers, strip denylists, capability allowlists, translation maps — and flag if the new entry is missing from any. Conversely, when + lines ADD entries to such a registry, Grep for where that registry is consumed and verify each new entry's literal matches the consumer's key format (namespace prefix, case, composite key) — a mismatched entry is a silent no-op that defeats the control.
-  - GATE/ACTION FIELD MISMATCH: when + lines add or modify an authorization/policy check, identify which request field(s) the gate reads vs which field(s) the downstream operation uses to select the target resource. If they differ (gate checks `parent`, action derives target from `name`; gate checks org A, action writes to org from a separate param), the gate is bypassable.
-  - RESOURCE-BOUND PLACEMENT: when + lines parse/decompress/fetch/loop over attacker-influenced input, verify size/time/count caps guard the ACTUAL peak allocation — not a post-flush output, post-decompress buffer, per-iteration (not total) timeout, unclamped arithmetic (subtraction underflow, multiplication overflow), or first-element-only invariant. The finding is the cap defeat, not the DoS itself.
-  - UNDER-VALIDATED SINK ARG: when + lines interpolate any externally-influenced value (incl. IPC, VCS-checkout content, env var, model output, domain-syntax strings) into a shell/path/loader/URI/structured-format sink, verify quoting, traversal/UNC/symlink stripping, and prod-mode guards apply to THIS arg — existing validators on sibling args do not cover it.
-
-Phase 3 — Assess.
-  Report when you can name (a) the source, (b) the sink, (c) the path with no effective mitigation. Medium-confidence is fine — a separate adjudication pass will filter; your job is RECALL, not precision. Do report logic/authorization bugs (missing ownership check, inverted condition, parser differential) even when no classic "sink" is involved.
-
-Do NOT report: missing best-practice/hardening with no concrete impact, test/mock files, outdated deps, or volumetric DoS (attacker just sends a lot). DO report DoS when the diff introduces a code defect that defeats an existing resource cap (cap on wrong accumulator, dead timeout handler, unclamped arithmetic, encoding amplification at flush) — those are logic errors with security impact.
-
-Distrust safety claims in comments ("validated upstream", "internal only"). Verify in code.
-
-Keep scanning after the first finding. Do NOT emit findings until you have Read EVERY touched file at least once — a more obvious pattern in file A does not excuse skipping file B. Aim for at least one candidate or explicit "no sink" verdict per touched file.
-
-Return an object with key `findings` — a list of {filePath, category,
-vulnerableCode, explanation, fix, severity, confidence} records. severity
-is "critical", "high", or "medium". Return findings:[] ONLY after you have
-Read every changed file in full and traced every new sink to a trusted
-source.
-
-BUDGET: you have at most ~15 tool calls. Spend them reading the changed files first, then 3-5 targeted Greps for callers/sinks. Do NOT exhaustively explore the repo — once you can name source→sink for each candidate (or rule it out), STOP. Partial findings are better than none."""

-# Find a working Python 3 interpreter and exec the hook with it.
-#
-# On Windows + Git Bash, `python3` typically resolves to the Microsoft Store
-# stub at C:\Users\<user>\AppData\Local\Microsoft\WindowsApps\python3, which
-# exits 49 silently in non-TTY subprocess context (a known Microsoft Store
-# stub behavior). This shim
-# probes each candidate with `-c ""` and skips any that fails, so the Store
-# stub falls through to the real python.org install (`python` in Git Bash) or
-# the `py -3` launcher.
-#
-# Order:
-#   1. python3   — canonical on macOS/Linux; the Store stub fails the probe.
-#   2. python    — python.org installs on Windows; some Linux distros (RHEL 7
-#                  EOL'd 2024-06) point this at Python 2, but `-c ""` succeeds
-#                  on Python 2 too — guard with a version check.
-#   3. py -3     — Windows Python launcher.
-#
-# Args after the shim path are passed straight through to the chosen
-# interpreter, so the hooks.json invocation is:
-#   bash "${CLAUDE_PLUGIN_ROOT}/hooks/sg-python.sh" \
-#        "${CLAUDE_PLUGIN_ROOT}/hooks/security_reminder_hook.py"

-
-# Git Bash / MSYS on Windows hands script paths to this shim in POSIX form
-# (`/c/Users/...`). When we exec a Windows `python.exe` (which we do on
-# Windows since `python3` is the Microsoft Store stub), python interprets the
-# leading `/` as the root of the current drive — e.g. `/c/Users/...` becomes
-# `C:\c\Users\...` or `D:\c\Users\...` (whichever drive the shell is on),
-# fails with ENOENT, and every Edit/Write/MultiEdit tool use blocks until the
-# session restarts. See anthropics/claude-plugins-official#2043.
-#
-# Fix: convert absolute path args to native Windows form via `cygpath -w`
-# before exec. `cygpath` is a Git Bash builtin; it's absent on macOS/Linux,
-# where the `command -v` guard makes this a no-op. `cygpath -w` is idempotent
