First100 — questions

Answers built from our own checks of this server.

Is First100 working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 368 checks got a reply (0.0%), average response time 245 ms. The bar chart above shows every period we have measured.

Is First100 still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

The registry lists First100 as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect First100?

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.

Does First100 need an API key?

No. First100 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 many people use First100?

The npm package first100-mcp was installed 42 times in the last week. Week over week that is +725%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
