What it does

The Postman Plugin for Claude Code is Postman's official plugin connecting a Postman workspace directly to Claude Code. Its /postman:test command runs a collection, parses the results, identifies which requests failed, and suggests fixes. It also supports mock servers, syncing collections, client-code generation, and security audits. It requires Claude Code v1.0.33 or later and a Postman API key, with OAuth recommended as the alternative to a raw API key.

How QA teams use it

Run /postman:test against a collection to get an immediate pass/fail breakdown plus suggested fixes for failing requests, without leaving the Claude Code session.
Spin up mock servers or sync collections between Postman and the codebase as part of an API testing workflow.
Generate client code from a collection or run a security audit alongside the functional test pass.
