Add mcp-context-warning plugin to warn about high MCP context usage This plugin warns users when their MCP servers are consuming significant context (>20k tokens). Many users don't realize MCP servers take up context space, which can lead to unexpectedly fast context exhaustion. The plugin: - Runs a SessionStart hook to check MCP configurations - Estimates token usage based on server and tool counts - Shows a warning with server breakdown if estimated usage > 20k tokens - Provides guidance on how to disable unused MCP servers Slack thread: https://anthropic.slack.com/archives/C07VBSHV7EV/p1765989316572149 2025-12-17 16:44:01 +00:00			`{`
