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:testagainst 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.
Setup
Requires Claude Code v1.0.33+ and a Postman API key (OAuth is the recommended alternative to a raw key).
Notes
Official Postman tool; freemium pricing follows Postman's own plan tiers.
