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.

Lumail — questions

Answers built from our own checks of this server.

Is Lumail working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 307 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 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.

Does Lumail need an API key?

No. Lumail completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. This is what we observed, not what the docs claim.

How fast is Lumail?

It answers our handshake in 307 ms on average, which is faster than 52% 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 that it is: 1 stars on GitHub, but no licence is declared, and without one the code is not open source by default.
