# MCP Calendar Server
A local [Model Context Protocol (MCP)](https://modelcontextprotocol.io) server that connects **Claude Desktop** to your **Google Calendar**.
This lets Claude manage calendar events, check schedules, and even calculate travel time between meetings — all locally and securely.
---
## Features
- **Manage Events** — Add, update, delete, or view Google Calendar events
- **Get Event Details** — Fetch details for specific events
- **Get Coordinates** — Retrieve coordinates for a given place using [OpenRouteService](https://openrouteservice.org/)
- **Travel Estimates** — Calculate distance and time between two points
- **Runs Locally** — No data leaves your computer
---
## How It Works
Claude Desktop supports MCP (Model Context Protocol) to interact with local or remote tools.
This project implements an MCP server in **Node.js** that communicates with Claude over `stdio`.

## Setup
### 1. Clone the repository
```bash
git clone https://github.com/username/mcp-calendar.git
cd mcp-calendar
```
### 2. Install dependencies
`npm install`
### 3. Create a .env file
```
GOOGLE_CLIENT_ID=your_google_client_id
GOOGLE_CLIENT_SECRET=your_google_client_secret
GOOGLE_REDIRECT_URI=your_google_redirect_uri
GOOGLE_REFRESH_TOKEN=your_google_refresh_token
OPENROUTESERVICE_API_KEY=your_openrouteservice_api_key
```
### 4. Run the MCP server
```bash
npm run build
npm start
```
### 5. Connecting to Claude Desktop
Open Claude Desktop
Go to Settings → Developer → Local MCP servers
Add a new local server configuration like:
```
{
"command": "node",
"args": ["C:\\path\\to\\build\\index.js"],
"env": {}
}
```
Restart Claude, it should automatically detect and connect to your MCP server.
