Nothing serious here today

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

This endpoint answered with an authorization challenge. The server is running, and it signs you in through your browser: there is no API key to paste.

Lumail — questions

Answers built from our own checks of this server.

Why is there no tool list for Lumail?

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 Lumail 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 259 ms. The bar chart above shows every period we have measured.

How do I connect Lumail?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form 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 Lumail?

No API key is involved. Lumail 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 Lumail?

It answers our handshake in 259 ms on average, which is faster than 65% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Lumail open source?

We cannot say either way: written in PHP and 2 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
