This endpoint answered with an authorization challenge. The server is running, and it signs you in through your browser: there is no API key to paste.

Cmssy — questions

Answers built from our own checks of this server.

Why is there no tool list for Cmssy?
The server answered our handshake with an authorization challenge, so it is running — but it will not describe its tools to an anonymous client. To see them you need to connect with your own credentials. We record it as alive, not as broken: 31.9% of checks in the last 24 hours got a reply.
Is Cmssy working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 29 of 91 checks got a reply (31.9%), average response time 327 ms. The bar chart above shows every period we have measured.
How do I connect Cmssy?
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. You sign in through your browser once and the client keeps the session: no key to copy, and it refuses anonymous clients.
How do you sign in to Cmssy?
No API key is involved. Cmssy answers our knock with an OAuth challenge, so you authorise it once in your browser and the client keeps the session. That is also why we see no tool list: it will not describe itself to an anonymous client, and that is the server working as intended, not a fault.
How fast is Cmssy?
It answers our handshake in 327 ms on average, which is faster than 43% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use Cmssy?
The npm package @cmssy/mcp-server was installed 1 866 times in the last week. Week over week that is -51%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Cmssy open source?
The code is open source: it is published under the MIT licence, written in TypeScript and 1 stars on GitHub. The licence covers the code in the repository, not the hosted service at api.cmssy.io, which runs on its operator's own terms.
