Rail Score — questions

Answers built from our own checks of this server.

Is Rail Score working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 54 ms. The bar chart above shows every period we have measured.

The registry lists Rail Score 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 Rail Score?

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 Rail Score need an API key?

No. Rail Score 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.

Is Rail Score open source?

The code is open source: it is published under the MIT licence, written in Python, 0 stars on GitHub and 2 open issues. The licence covers the code in the repository, not the hosted service at mcp.responsibleailabs.ai, which runs on its operator's own terms.
