Connects to your local Mac Calendar SQLite database and lets Claude search through archived events. Builds a local index on first run, then keeps it current by watching for database changes. Read-only access means you can query past and future events without worrying about accidental modifications. Install via pipx, run the indexer once, then hook it into Claude Code or Codex with watch mode enabled. Built by the same team behind mac-mail-mcp, currently in alpha. Useful when you need an assistant to reference your actual calendar history or find events by content without switching contexts.
