Postman

Postman brings the full Postman platform into Claude Code. It connects your Postman account via the MCP Server, syncs collections and environments, and pulls up API schemas and examples. You can browse and import collections, watch for collection updates, and map requests to local files so your code references stay in sync without flipping back to the Postman app.

You can generate client code and code snippets in multiple languages from collection requests, export SDKs, and create ready-to-run examples for teammates. The plugin runs collection and integration tests, reports failures with request/response logs, and starts mock servers from examples. It also publishes API documentation and runs security checks against your workspace to flag common misconfigurations or missing auth flows.

Use it when you’re coding in Claude Code and need to run a Postman test, generate a TypeScript client, or spin up a mock server without opening a browser. For example, when a backend change breaks an endpoint, you can pull the latest collection, run failing tests, inspect responses, generate a patched client, and push documentation updates — all from the editor, saving context switches and time.
