Nothing serious here today

Today is the operative word: we check Suppscience every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Suppscience — questions

Answers built from our own checks of this server.

What can Suppscience do?

It exposes 4 tools, read directly from the server on our last check. Among them: get_guide, get_supplement, list_guides, search_supplements. 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 Suppscience working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 103 ms. The bar chart above shows every period we have measured.

How do I connect Suppscience?

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 Suppscience need an API key?

No. Suppscience completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Suppscience?

It answers our handshake in 103 ms on average, which is faster than 83% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
