Overview

What is MCP Calendar Tool Server?

A FastAPI-based MCP (Model Context Protocol) server that provides calendar management tools—check availability, add, update, and delete events—for AI agents running in n8n.

How to use MCP Calendar Tool Server?

Clone the repository, install dependencies with pip install -r requirements.txt, create a .env file with your API key, then run uvicorn main:app --host 0.0.0.0 --port 5000. Connect n8n’s MCP Client node to the SSE endpoint at http://localhost:8000/mcp-events.

Frequently asked questions

What dependencies are required?

Python packages listed in `requirements.txt`; install with `pip install -r requirements.txt`.

How is authentication handled?

The server uses an API key set in the `.env` file as `API_KEY`. All tool execution requests require the `X-API-Key` header.

Does it integrate with real calendar services?

No, the current version uses mock implementations. Future improvements include integration with Google Calendar, Cal.com, and others.

What transport does the server use?

It uses Server-Sent Events (SSE) for tool discovery (`GET /mcp-events`) and HTTP POST for tool execution (`POST /mcp/message`).

What are the current limitations?

The server provides mock data only, no real calendar backend. It requires Python 3 and a running FastAPI instance.
