Prembly MCP Server — questions

Answers built from our own checks of this server.

Why is there no tool list for Prembly MCP Server?

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: 100.0% of checks in the last 24 hours got a reply.

Is Prembly MCP Server working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 18 of 18 checks got a reply (100.0%), average response time 558 ms. The bar chart above shows every period we have measured.

How do I connect Prembly MCP Server?

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 Prembly MCP Server?

No API key is involved. Prembly MCP Server 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 Prembly MCP Server?

It answers our handshake in 558 ms on average, which is faster than 21% 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.
