Calendar MCP server FAQ

What is the best Calendar MCP server?

Based on GitHub stars and recent activity, google_workspace_mcp by taylorwilsdon (★ 3.3k, updated 4 days ago) is the most popular actively maintained option on HookMCP, followed by keeper.sh and google-docs-mcp. The right choice depends on whether you need write access, a hosted (remote) endpoint, or a server that runs locally without an API key.

How do I install a Calendar MCP server in Claude, Cursor or VS Code?

Open the server's page on HookMCP, choose your client tab (Claude Desktop, Cursor, VS Code or Claude Code) and copy the config — 4 of the 6 servers here have one-click install links for Cursor and VS Code. Restart your AI app and the new tools appear automatically.

Do Calendar MCP servers need an API key?

4 of 6 servers here mention API keys or tokens in their README; 2 don't mention any. Check each listing's Details panel, and pass keys as environment variables rather than pasting them into chat.
