Koskamo

Google Calendar MCP

A community-built Model Context Protocol server for Google Calendar that enables agents to read and write events, manage recurrence, check availability, and handle calendars. It uses per-user OAuth against the user's own Google account and enforces correct handling of all-day events, IANA time zones, and availability logic to avoid common pitfalls in calendar data interpretation.
