CMS Medicare Data — questions
Answers built from our own checks of this server.
What can CMS Medicare Data do?
It exposes 5 tools, read directly from the server on our last check. Among them: get_chronic_conditions, get_hospital_quality, get_hospital_readmissions, get_medicare_enrollment, get_medicare_spending. 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 →
What is CMS Medicare Data mostly used for?
Its tools cluster around hospital and medicare. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is CMS Medicare Data 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 549 ms. The bar chart above shows every period we have measured.
How do I connect CMS Medicare Data?
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 CMS Medicare Data need an API key?
No. CMS Medicare Data completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is CMS Medicare Data?
It answers our handshake in 549 ms on average, which is faster than 25% 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.
