What is the Calendar MCP server?

Calendar MCP server exists for a simple reason — assistants are far more useful when they can act on Calendar directly instead of describing what you should do. Calendar Ai MCP server. Tools: create event, find free slot, calculate duration. Built by ME...

What you get

Calendar utilities MCP — scheduling, availability checking, timezone handling, ICS export. MIT.

Setting it up

The server ships on npm as @smithery/cli, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.

What the assistant can call

Once Calendar is connected, these are the calls the assistant has available:

  • Well — documented API
  • Production-ready — Active maintenance
  • Pro — ** $99/mo — Full MCP suite + EU AI Act tracking
  • Enterprise — ** $499/mo — Custom dev + SLA + Dedicated support
  • Domain — Purpose
  • Tier — Price

Before you rely on it

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the calendar mcp server does with a few real requests.

Choosing this one

This sits in the planning and project tracking group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Calendar's toolset — Well, Production-ready, Pro and 3 more — is a fair guide to whether it matches your workflow. It is maintained by CSOAI-ORG; worth a glance at recent repository activity before you build anything load-bearing on it.

This entry was verified against Calendar's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
