Nothing serious here today

Today is the operative word: we check TestMu AI (formerly LambdaTest) every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

TestMu AI (formerly LambdaTest) — questions

Answers built from our own checks of this server.

Why is there no tool list for TestMu AI (formerly LambdaTest)?

The server answered our handshake with an authorization challenge, so it is running — but it will not describe its tools to an anonymous client. To see them you need to connect with your own credentials. We record it as alive, not as broken: 100.0% of checks in the last 24 hours got a reply.

Is TestMu AI (formerly LambdaTest) working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 375 ms. The bar chart above shows every period we have measured.

How do I connect TestMu AI (formerly LambdaTest)?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You sign in through your browser once and the client keeps the session: no key to copy, and it refuses anonymous clients.

How do you sign in to TestMu AI (formerly LambdaTest)?

No API key is involved. TestMu AI (formerly LambdaTest) answers our knock with an OAuth challenge, so you authorise it once in your browser and the client keeps the session. That is also why we see no tool list: it will not describe itself to an anonymous client, and that is the server working as intended, not a fault.

How fast is TestMu AI (formerly LambdaTest)?

It answers our handshake in 375 ms on average, which is faster than 41% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is TestMu AI (formerly LambdaTest) open source?

We cannot say either way: 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
