API Testing MCP server

This is a helper that lets your AI actually talk to the web services your team uses, instead of just talking about them. You describe what you want to check, and the AI sends the request, looks at what comes back, and tells you if it worked. It is handy for anyone who tests or pokes at APIs but does not want to write code or learn a testing tool.

What this MCP server does

You ask your AI something like send a GET request to the users endpoint. The AI passes that to this helper program. The helper sends the real request to your service, waits for the answer, and hands the result back to the AI. The AI then shows you the status code, the timing, and the response body in plain words. If you set up an environment first, the helper fills in the base address and any tokens for you, so you can just say the short path.

What you can do with it

• Send any kind of request (GET, POST, PUT, DELETE) to your service
• Check that a response has the right status, body, and speed
• Chain steps together, like logging in and then using the token
• Import your API description and ask what each endpoint needs
• Generate fake test data that matches your API's rules
• Run all your saved tests at once and get a pass or fail summary
• Compare the same endpoint on two different environments

Try asking your AI

• “Send a GET request to /users and show me the first three results”
• “Verify that DELETE /users/5 returns 204”
• “Log in as admin, grab the token, then fetch the dashboard stats”
• “How fast is /health with 50 requests at the same time”

What it gives back to you

You get a short summary in the chat: the status code, how long it took, and the response body. For checks, you get a clear pass or fail line for each thing you asked about. For load tests, you get numbers like average time and the slowest requests. For saved test runs, you get a list showing which ones passed and which ones failed.

Before you start

Who it's for

Anyone who tests or explores web services at work, like QA testers, support engineers, or developers who want a quick way to check an API without leaving their chat.
