Browser Proof — questions

Answers built from our own checks of this server.

Is Browser Proof working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 182 checks got a reply (0.0%), average response time 48 ms. The bar chart above shows every period we have measured.

Is Browser Proof 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 Browser Proof 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 Browser Proof?

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 Browser Proof need an API key?

No. Browser Proof 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.
