Postman MCP Server

Postman's official MCP server: workspaces, collections, specs and environments straight from your agent

Install

npx @postman/postman-mcp-server

Local run with POSTMAN_API_KEY. --code and --full change the tool set.

This is third-party code. Review the repository files before installing.

What it does

The server connects an agent to Postman workspaces. The agent creates and tags collections, updates their docs, manages environments and variables, builds specs from code and generates collections from them. Code mode generates client code from public and internal API definitions, and Learn mode searches Postman docs. It runs hosted with OAuth or locally via npx, which you need for testing APIs on your own machine.

Who it is for. For developers and QA engineers who manage APIs in Postman.

Good fit when

  • You need to sync a Postman collection with code changes
  • You want to run API tests from a collection through the agent
  • You need client code generated from an API definition

Not a fit when

  • Your team does not use Postman
  • You want to test a local API through the hosted server: it cannot reach your machine

Example request

Update the Orders API collection in Postman with the new endpoints from this controller

Limitations

Requires a Postman account. The hosted server supports OAuth, while the EU server and the local server work only with a Postman API key. Full mode exposes over a hundred tools, which weighs on context. Server code syncs from Postman's internal repo, so pull requests to src are not merged. Postman availability from Russia is unverified.

How to disable. Remove the postman server from your MCP client config, for example claude mcp remove postman, and revoke the API key or OAuth access in Postman settings.

README in short

The README describes four tool configurations, OAuth or API key auth, and a quick start for remote and local setups. Each supported agent links to setup steps in Postman docs. It also covers the EU server, typical use cases and a public collection for testing the server.

FAQ

Which mode should I pick?

Minimal, the default, suits editing single collections, environments and workspaces. Code is for client code generation, Full for all Postman API features, Learn for docs search.

Is there an EU server?

Yes, at mcp.eu.postman.com with /mcp, /code and /minimal paths, but only with API key auth. The local server needs --region eu.
