World Business Calendar — questions

Answers built from our own checks of this server.

Why is there no uptime for World Business Calendar?
World Business Calendar 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 @appmonster/mcp-world-calendar.
How do I connect World Business Calendar?
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 runs locally, so the command pulls @appmonster/mcp-world-calendar straight from npm; nothing to host, nothing to sign up for.
Is World Business Calendar open source?
Yes — it is published under the MIT licence, written in TypeScript 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.
