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.

FreeRDC — questions

Answers built from our own checks of this server.

Why is there no tool list for FreeRDC?

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 FreeRDC working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 63 of 63 checks got a reply (100.0%), average response time 344 ms. The bar chart above shows every period we have measured.

How do I connect FreeRDC?

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 FreeRDC?

No API key is involved. FreeRDC 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 FreeRDC?

It answers our handshake in 344 ms on average, which is faster than 47% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is FreeRDC open source?

Yes — it is published under the AGPL-3.0 licence, written in JavaScript and 1 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
