Nothing serious here today

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

DAG Studio WebMCP — questions

Answers built from our own checks of this server.

Why is there no tool list for DAG Studio WebMCP?

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 DAG Studio WebMCP working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 142 ms. The bar chart above shows every period we have measured.

How do I connect DAG Studio WebMCP?

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. You will need your own key: it refuses anonymous clients.

Does DAG Studio WebMCP need an API key?

Yes. Every time we knock, DAG Studio WebMCP 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 DAG Studio WebMCP?

It answers our handshake in 142 ms on average, which is faster than 77% 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.

Is DAG Studio WebMCP open source?

Yes — it is published under the MIT licence, written in HTML and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
