Postman Echo Mcp

Lets an assistant send HTTP requests to the Postman Echo service and inspect the echoed responses, with no API key required.

What you can do

This server connects an assistant to Postman Echo, a public service that returns the details of the HTTP requests it receives. The assistant can issue requests and read back the echoed method, headers, query parameters, and body, which is useful for checking how a request is formed. It runs locally over stdio and declares no authentication.

When to use it

Worth adding when you want an assistant to test or demonstrate HTTP request construction and see exactly what a server receives. It is a lightweight diagnostic aid rather than a tool for real APIs or production data.

Requirements

Runs as a local process on the user's machine via the npm package postman-echo-mcp over stdio, so Node.js and npm are needed. No accounts, API keys, environment variables, or headers are declared. Network access to the Postman Echo service is required.
