Postman MCP: Documentation

Connection

• Remote: https://mcp.postman.com/mcp (Streamable HTTP). Auth: a Postman API key is required (passed as a header, created under Settings → API Keys); OAuth is currently available only to accounts in the US region.
• Local: the postman-mcp-server package (stdio) from the postmanlabs/postman-mcp-server repo — the same toolset without a remote connection.

Tools

A wrapper over the Postman API: collections (fetch, create, run requests), workspaces, environments and variables, mock servers (create and manage), running Postman monitors. A standout feature is generating a brand-new MCP server straight from a Postman API Network collection (100,000+ public APIs): the agent gets ready-made tools for a third-party service with no manual endpoint mapping.

Agent flow

"Find the Stripe API collection and list its endpoints", "generate an MCP server from the public SendGrid collection", "spin up a mock server for this collection and run a test request".

Limits

OAuth is restricted to US-region accounts — everyone else needs an API key. The repository is relatively young (250 stars), so the tool interface may still evolve.

Pricing

The MCP server itself is free to use with any Postman account; some features (workspace, mock server and monitor limits) depend on your Postman plan (Free/Basic/Professional/Enterprise).
