607. OpenClaw Calendar Skill - Calendar Management

Basic Information

Product Description

The OpenClaw Calendar Skill is a category of calendar management skills that enables AI agents to create, update, query, and manage calendar events. This skill integrates calendar services like Google Calendar and Outlook through the MCP protocol, supporting natural language-driven schedule management.

In March 2026, Google released the open-source Workspace CLI, which includes an MCP server that directly exposes APIs for Drive, Gmail, Calendar, Docs, and Sheets, along with a SKILL.md file containing over 100 Agent Skills. Additionally, the community has developed several mature Google Calendar MCP server implementations, such as nspady/google-calendar-mcp, which supports multi-account calendar management.
