Overview
CalendarMCP
The hosted Google Calendar MCP server. Connect any AI agent to your Google Calendar in about two minutes. No self-hosting, no Docker, no credentials.json.
Why CalendarMCP
- Zero setup. One Google OAuth click. Instant API key.
- HTTP transport. Works with Claude.ai, Claude Code, Cursor, OpenClaw, Continue, Cline, Windsurf, Goose, n8n, and any HTTP-capable MCP client.
- Batch operations. batch_update_events updates up to 50 events in one concurrent call.
- Multi-account, one key. Connect any number of Google accounts (mix OAuth + service-account-shared calendars) under a single API key. Reading fans out across all of them.
- Google Advanced Protection support. The only hosted MCP that works for GAP users (via service-account sharing).
- Per-calendar Read/Write matrix. Tighten what each agent can touch from the dashboard without minting new keys.
