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

Claude Code Claude Desktop Codex Cursor VS Code

run in your terminal

claude mcp add caldav-mcp -- npx -y caldav-mcp

This one needs environment variables set before it will start: CALDAV_BASE_URL (Base URL of the CalDAV server (e.g. https://caldav.example.com)), CALDAV_USERNAME (Username for CalDAV authentication), CALDAV_PASSWORD (Password for CalDAV authentication). The author declared them in the registry entry; get the values from the project itself.

Caldav MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Caldav MCP?

Caldav MCP runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package caldav-mcp was installed 224 times last week.

How do I connect Caldav MCP?

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 runs locally, so the command pulls caldav-mcp straight from npm; nothing to host, nothing to sign up for.

How many people use Caldav MCP?

The npm package caldav-mcp was installed 224 times in the last week. Week over week that is +23%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Caldav MCP open source?

Yes — it is published under the MIT licence, written in TypeScript, 100 stars on GitHub and 5 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
