Nothing serious here today

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

Agent-Native Calendar — questions

Answers built from our own checks of this server.

Why is there no tool list for Agent-Native Calendar?

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 Agent-Native Calendar working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 58 of 58 checks got a reply (100.0%), average response time 1835 ms. The bar chart above shows every period we have measured.

How do I connect Agent-Native Calendar?

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 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 Agent-Native Calendar?

No API key is involved. Agent-Native Calendar 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.

Is Agent-Native Calendar open source?

We cannot say that it is: written in TypeScript, 4 700 stars on GitHub and 12 open issues, but no licence is declared, and without one the code is not open source by default.
