It provides full API lifecycle management, and best practices when working with Postman APIs. ## What's included: - Commands for setting up the Postman MCP Server (no more manual installs!), working with Collections, Tests, Mock Servers, and generating code and documentation from Collections - Skills for API discovery and client code generation, OpenAPI spec generation, Postman CLI workflows, and API best practices - Agent for reviewing API production readiness and providing recommendations based on the <a href="https://www.postman.com/ai/90-day-ai-readiness-playbook/">Postman API Readiness Guide</a>. ## Installation Install from Anthropic's official plugin marketplace. In Claude Code: ``` /plugin install postman@claude-plugins-official ``` Or from the terminal: ```bash claude plugin install postman@claude-plugins-official ``` <details> <summary>Alternative: install from GitHub</summary> ```bash claude plugin install github:Postman-Devrel/postman-claude-code-plugin ``` </details> <details> <summary>Alternative: load from a local clone</summary> ```bash git clone https://github.com/Postman-Devrel/postman-claude-code-plugin.git cd your-api-project/ claude --plugin-dir /path/to/postman-claude-code-plugin ``` </details> ## Quick Start 1. Start Claude Code: ```bash claude ``` 2. Run setup: ``` /postman:setup ``` 3. Authenticate when prompted — **OAuth (recommended)**, which opens a browser sign-in with no key copying, or an API key: ```bash export POSTMAN_API_KEY=PMAK-your-key-here ``` If you use an API key, add it to your shell profile (`~/.zshrc` or `~/.bashrc`) to persist across sessions. Get one at [go.postman.co/settings/me/api-keys](https://go.postman.co/settings/me/api-keys). That's it. The plugin auto-configures the Postman MCP Server, verifies your connection, and lists your workspaces. You're ready to go. ## Commands | Command | What It Does | |---------|-------------| | `/postman:setup` | Configure API key, verify connection, select workspace | | `/postman:sync` | Create or update Postman collections from OpenAPI specs | | `/postman:search` | Find APIs across your org's resources, your workspaces, and the public Postman network | | `/postman:context` | Fetch real API definitions, generate and maintain typed client code | | `/postman:test` | Run collection tests, diagnose failures, suggest fixes | | `/postman:mock` | Create mock servers for frontend development | | `/postman:docs` | Generate, improve, and publish API documentation | | `/postman:security` | Security audit against OWASP API Top 10 | | `/postman:learn` | Search the Postman Learning Center for how-to guidance and suggested workflows (Full mode) | ## What You Can Do ### Sync your API to Postman ``` "Sync my OpenAPI spec with Postman" → Detects local spec, creates/updates collection, sets up environment ``` ### Generate client code from private APIs ``` "Generate a TypeScript client for the payments API" → Reads your Postman collection, detects project language, writes typed code ``` ### Search across your workspace ``` "Is there an endpoint that returns user emails?" → Searches across your org's collections, drills into endpoint details, shows response shapes ``` ### Run API tests ``` "Run the tests for my User API collection" → Executes collection, parses results, diagnoses failures, suggests code fixes ``` ### Create mock servers ``` "Create a mock for frontend development" → Generates missing examples, creates mock, provides integration config ``` ### Audit API security ``` "Run a security audit on my API" → 20+ checks including OWASP Top 10, severity scoring, remediation guidance ``` ### Check if your API is agent-ready ``` "Is my API ready for AI agents?" → 48 checks across 8 pillars, scored 0-100, prioritized fix recommendations ``` ## Natural Language Routing You don't need to remember command names. Claude matches your intent to the right command or skill natively: - "Sync my collection" runs `/postman:sync` - "Check for vulnerabilities" runs `/postman:security` - "Is my API agent-ready?" triggers the readiness analyzer ## API Readiness Analyzer The built-in readiness analyzer evaluates APIs for AI agent compatibility across 8 pillars: | Pillar | What It Checks | |--------|---------------| | Metadata | operationIds, summaries, descriptions, tags | | Errors | Error schemas, codes, retry guidance | | Introspection | Parameter types, required fields, examples | | Naming | Consistent casing, RESTful paths | | Predictability | Response schemas, pagination, date formats | | Documentation | Auth docs, rate limits | | Performance | Rate limit headers, caching, bulk endpoints | | Discoverability | OpenAPI version, server URLs | **70%+ with no critical failures = Agent-Ready.** ## Requirements - Claude Code v1.0.33+ - A Postman account — authenticate via OAuth during `/postman:setup`, or set a `POSTMAN_API_KEY` environment variable - No Python, Node, or other runtime dependencies ## How It Works The plugin bundles a `.mcp.json` file that auto-configures the [Postman MCP Server](https://github.com/postmanlabs/postman-mcp-server) when installed. All commands communicate with Postman through MCP tools. No scripts, no dependencies, pure MCP. By default the plugin connects to the full Postman MCP Server (100+ tools). Recent Claude Code versions load MCP tool schemas on demand, so the full server adds little context overhead. If you're on an older client or want a lighter session, set `POSTMAN_MCP_MODE` before starting Claude Code to pick a smaller server mode: ```bash export POSTMAN_MCP_MODE=minimal # ~42 CRUD tools; code-generation (context) tools unavailable export POSTMAN_MCP_MODE=code # ~24 read-only tools for API discovery and client code generation ``` ## License Apache-2.0 ## See Also - [Postman Plugin for Cursor](https://github.com/Postman-Devrel/cursor-postman-plugin) - Same capabilities, adapted for Cursor IDE - [Postman Agent Skills](https://github.com/Postman-Devrel/agent-skills) - Portable skills for any skills.sh-compatible agent - [Postman Cursor Rules](https://github.com/Postman-Devrel/postman-cursor-rules) - Lightweight MCP config + rules for Cursor ## Links - [Postman MCP Server Docs](https://learning.postman.com/docs/developer/postman-mcp-server/) - [Get a Postman API Key](https://go.postman.co/settings/me/api-keys) - [Postman Status](https://status.postman.com)
