About caldav-mcp
dominik1001/caldav-mcp
A CalDAV client using Model Context Protocol (MCP) to expose calendar operations as tools for AI assistants.
Implements calendar CRUD operations (create, list, delete events) with time-range filtering and multi-calendar support, communicating via MCP's stdio transport. Built in TypeScript with environment-based CalDAV server configuration, it integrates directly into AI assistant platforms like Claude Desktop through standard MCP server setup. The tool exposes granular operations—event creation with start/end times, querying by timeframe, and deletion by UID—enabling sophisticated calendar automation workflows.
About mcp-google-calendar
guinacio/mcp-google-calendar
A MCP server that allows Claude and other MCP clients to interact with Google Calendar. This server enables AI assistants to manage your calendar events, check availability, and handle scheduling tasks.
Implements dual transport modes (STDIO for Claude Desktop and SSE for web clients) with automatic OAuth 2.0 authentication flow and token persistence. The server provides comprehensive calendar operations including conflict detection, timezone-aware event scheduling with recurring RRULE support, and multi-user availability checking across calendars. Built on Python 3.12+ with Pydantic schemas and integrates directly with Google Calendar API through the Model Context Protocol framework.
