GSC MCP Core — questions

Answers built from our own checks of this server.

Is GSC MCP Core working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 14 of 92 checks got a reply (15.2%), average response time 1089 ms. The bar chart above shows every period we have measured.
Is GSC MCP Core 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 GSC MCP Core 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 GSC MCP Core?
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 GSC MCP Core need an API key?
No. GSC MCP Core 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 GSC MCP Core?
It answers our handshake in 1089 ms on average, which is faster than 3% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
