Foo Guard Library — questions

Answers built from our own checks of this server.

What can Foo Guard Library do?
It exposes 2 tools, read directly from the server on our last check. Among them: get_library_item, search_library. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Foo Guard Library working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 27 of 92 checks got a reply (29.3%), average response time 331 ms. The bar chart above shows every period we have measured.
The registry lists Foo Guard Library 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 Foo Guard Library?
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 Foo Guard Library need an API key?
No. Foo Guard Library completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Foo Guard Library?
It answers our handshake in 331 ms on average, which is faster than 42% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
