postman is a Claude Code plugin that adds full API lifecycle management by connecting to the Postman MCP Server, according to the GitHub README. It installs as a single local plugin and provides commands to sync collections from OpenAPI specs, generate typed client code, search APIs, run collection tests, create mock servers, publish documentation, and run security audits. The README also describes a bundled agent that evaluates API "agent-readiness" across 8 pillars with 48 checks, scoring APIs from 0-100. Authentication supports either OAuth or a Postman API key, and the README lists Claude Code v1.0.33+ as a requirement with no other runtime dependencies.

Overview

According to the Postman documentation page, Postman provides a Model Context Protocol (MCP) server that lets AI agents such as Claude, Cursor, and VS Code manage Postman resources — workspaces, collections, specifications, mocks, and monitors — by translating natural-language commands into API workflows. The MCP server is offered as a remote server (streamable HTTPS) or a local server (STDIO, via source or Docker), and both support tool configurations called Minimal, Code, Full, and Learn to control which tools are loaded.

What you can do with postman

  • Run /postman:setup to configure API key or OAuth authentication, verify the connection, and select a workspace
  • Run /postman:sync to create or update Postman collections from OpenAPI specs
  • Run /postman:search to find APIs across your org's resources, your workspaces, and the public Postman network
  • Run /postman:context to fetch real API definitions and generate/maintain typed client code
  • Run /postman:test to execute collection tests, diagnose failures, and get suggested fixes
  • Run /postman:mock to create mock servers for frontend development
  • Run /postman:docs to generate, improve, and publish API documentation
  • Run /postman:security to audit APIs against the OWASP API Top 10
  • Use the built-in readiness analyzer to score API agent-readiness (48 checks across 8 pillars, 0-100)
