CalMesh is an AI-first calendar API that aggregates Google, Microsoft, Apple, and CalDAV calendars into a single unified REST API. It includes an official MCP (Model Context Protocol) server so AI agents can manage calendars natively.

What is the CalMesh MCP server?

The CalMesh MCP server is an official Model Context Protocol server with 19 tools that lets AI assistants like Claude, ChatGPT, and others directly manage calendars, check availability, create bookings, and run scheduling polls. Install with: npx @calmesh/mcp-server

How much does CalMesh cost?

CalMesh starts at EUR 8/year for the Agent plan (REST API, MCP server, webhooks, scoped API keys, iCal feed). The Pro plan is EUR 12/year (adds booking pages, embeddable widget, email notifications). The Business plan is EUR 15/user/year during beta (normally EUR 99/user/year) and adds AI-first support with 48h SLA, team admin, and aggregated billing. All plans include a 14-day free trial.

Which calendar providers does CalMesh support?

CalMesh supports Google Calendar, Microsoft Outlook/Exchange, Apple Calendar (via CalDAV), generic CalDAV servers, and iCal feed URLs. All sources are merged into unified calendars with consistent event schemas.

How do I connect CalMesh to my AI agent?

Sign up at calmesh.xyz, connect your calendars, generate a scoped API key, then either use the REST API directly or install the MCP server with: CALMESH_API_KEY=cm_live_... npx @calmesh/mcp-server. Setup takes about 60 seconds.
