Cvserver missed 2 checks this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

This endpoint answered with an authorization challenge. The server is running, but it did not say what kind of credentials it expects.

Cvserver — questions

Answers built from our own checks of this server.

Why is there no tool list for Cvserver?

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 Cvserver 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 556 ms. The bar chart above shows every period we have measured.

How do I connect Cvserver?

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 will need your own credentials: it refuses anonymous clients.

Does Cvserver need an API key?

Yes. Every time we knock, Cvserver answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.

How fast is Cvserver?

It answers our handshake in 556 ms on average, which is faster than 20% 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.

Is Cvserver open source?

We cannot say either way: written in MDX and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
