  • Security Auditing - Check APIs for security issues
  • Code Generation - Generate code snippets in Python, JavaScript, Go, and more

Usage

Natural Language

/postman
Show me all my collections
/postman
Create a mock server for my Payment API
/postman
Is my API ready for AI agents?

Common Operations

Task Example
List collections "Show my collections"
Create collection "Create a collection called User API"
Run tests "Run tests for Payment API with staging environment"
Check monitors "How are my monitors doing?"
Create mock "Create a mock server for Order API"
Analyze agent-readiness "Is my API ready for AI agents?"
Security audit "Check my API for security issues"

Setup

Prerequisites

  • Python 3.7+
  • Postman API Key

Configuration

  1. Get your API key from Postman Account Settings

  2. Create a .env file:

cp .env.example .env
# Edit .env and add: POSTMAN_API_KEY=PMAK-your-key-here

Agent-Readiness Analysis

This plugin includes Clara integration for grading APIs on AI agent compatibility.

Clara checks 8 pillars:

  1. Metadata - operationIds, summaries, descriptions
  2. Errors - Structured error responses
  3. Introspection - Parameter types, examples
  4. Naming - Consistent casing, RESTful paths
  5. Predictability - Response schemas
  6. Documentation - Auth docs, rate limits
  7. Performance - Response times
  8. Discoverability - Server URLs, spec accessibility

Score 70%+ with no critical failures = Agent Ready

Works With

This plugin complements Postman's MCP Server for live API operations.
