Postman Agent Skills

Give your AI coding agent full access to Postman. Sync collections, generate client code, run tests, create mocks, publish docs, audit security, and analyze API readiness for AI agents.

Works with Claude Code, Cursor, Windsurf, Codex, and 40+ other agents.

Install

npx skills add Postman-Devrel/agent-skills

This installs two skills:

Skill	What It Does
postman	Full API lifecycle: sync specs, generate code, run tests, create mocks, publish docs, audit security
postman-api-readiness	Analyze any API for AI agent compatibility (48 checks, 8 pillars, 0-100 scoring)

Prerequisites

1. Postman API Key: Get one at postman.postman.co/settings/me/api-keys

2. Set the environment variable:

   export POSTMAN_API_KEY=PMAK-your-key-here

   Add to ~/.zshrc or ~/.bashrc to persist.

3. Postman MCP Server: The skills use Postman's MCP Server for all operations. If you're using the Postman Claude Code Plugin, MCP is already configured. Otherwise, add to your MCP config:

   {
     "mcpServers": {
       "postman": {
         "type": "http",
         "url": "https://mcp.postman.com/mcp",
         "headers": {
           "Authorization": "Bearer ${POSTMAN_API_KEY}"
         }
       }
     }
   }

What You Can Do

Sync Collections

Push OpenAPI specs to Postman, create collections, keep everything in sync.

"Sync my OpenAPI spec to Postman"
"Create a collection from my local API spec"
"Push my endpoint changes to Postman"

Generate Client Code

Generate typed clients from your Postman collections in TypeScript, Python, Go, Rust, Java, or Ruby.

"Generate a TypeScript client from my Users API collection"
"Create a Python SDK for the Pet Store API"

Run Tests

Execute Postman collection tests, diagnose failures, and fix code.

"Run the tests for my API collection"
"Why are my API tests failing?"

Create Mock Servers

Spin up mock servers for frontend development and testing.

"Create a mock server for my collection"
"I need a fake API for frontend development"

Publish Documentation

Analyze, improve, and publish API docs.

"How complete is my API documentation?"
"Generate docs for my OpenAPI spec"
"Publish my collection docs"

Security Audit

Audit APIs against OWASP API Security Top 10.

"Run a security audit on my API"
"Check my spec for vulnerabilities"

API Readiness Analysis

Score your API for AI agent compatibility.

"Is my API agent-ready?"
"Scan my OpenAPI spec for agent compatibility"
"How do I get my API to a 90% readiness score?"

About

Built by the Postman Developer Relations team. These skills give AI coding agents native access to Postman's API platform, turning your agent into a full API development partner.

The postman skill covers the complete API lifecycle: design, build, test, secure, deploy, observe, and distribute. The postman-api-readiness skill is a standalone analyzer that evaluates any OpenAPI spec for AI agent compatibility using a framework of 48 checks across 8 pillars.
