Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Endpoint below is the one we actually reach during checks — not the one copied from a README. Last verified 12 min ago.

run in your terminal

This one needs environment variables set before it will start: OA_API_KEY (OpenAgenda API key (the stdio credential — a least-privilege/read key is advised). The hosted remote uses OAuth instead.), OA_BASE_URL (v3 API base URL (defaults to https://api.openagenda.com/v3).), OA_EXECUTOR (Code engine: node (default — Node's permission sandbox: no filesystem/subprocess; network NOT bounded) or deno (adds a scoped network egress boundary; recommended hardening, needs deno installed).), OA_LOCAL_NO_SANDBOX (Disable the Node permission sandbox entirely (bare node, NO boundary at all) — trusted/dev use only.). The author declared them in the registry entry; get the values from the project itself.

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.

OpenAgenda — questions

Answers built from our own checks of this server.

Why is there no tool list for OpenAgenda?
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 OpenAgenda 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 136 ms. The bar chart above shows every period we have measured.
How do I connect OpenAgenda?
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 OpenAgenda?
No API key is involved. OpenAgenda 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 OpenAgenda?
It answers our handshake in 136 ms on average, which is faster than 79% 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.
How many people use OpenAgenda?
The npm package @openagenda/mcp was installed 121 times in the last week. Week over week that is +45%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is OpenAgenda open source?
We cannot say either way: written in JavaScript, 2 stars on GitHub and 3 open issues, but we could not determine the licence, and without one the code is not open source by default.
