CalDAV Nectcloud calendar integration. Manage calendars, events, attendees, etc.

A Model Context Protocol (MCP) server for Nextcloud Calendar integration.

- Fetch calendars from Nextcloud
- ADHD-friendly organization features
- MCP protocol support (Streamable HTTP and Legacy HTTP+SSE)

The easiest way to use this package is with npx:

# Install globally npm install -g mcp-nextcloud-calendar # Or install locally npm install mcp-nextcloud-calendar

To use with an MCP client (like Claude), add this configuration to your MCP client settings:

{ "mcpServers": { "nextcloud-calendar": { "command": "npx", "args": ["-y", "mcp-nextcloud-calendar"], "env": { "NEXTCLOUD_BASE_URL": "https://your-nextcloud-server.com", "NEXTCLOUD_USERNAME": "your-username", "NEXTCLOUD_APP_TOKEN": "your-app-token" } } } }

You can pin to a specific version of the package:

{ "mcpServers": { "nextcloud-calendar": { "command": "npx", "args": ["-y", "mcp-nextcloud-calendar@0.1.0"], "env": { "NEXTCLOUD_BASE_URL": "https://your-nextcloud-server.com", "NEXTCLOUD_USERNAME": "your-username", "NEXTCLOUD_APP_TOKEN": "your-app-token" } } } }

The server uses these environment variables, with defaults where possible:
- Clone the repository
- Install dependencies:
- Edit the.envfile with your Nextcloud credentials.
- Log in to your Nextcloud instance
- Go to Settings → Security → App Passwords
- Create a new app password with a name like "MCP Calendar"
- Copy the generated token to your.envfile

# Build the project npm run build # Run in development mode npm run dev # Run tests npm run test # Run linting npm run lint # Format code npm run format

- /mcp- Primary MCP endpoint (Streamable HTTP transport)
- /sseand/messages- Legacy MCP endpoints (HTTP+SSE transport)
- GET /health- Health check endpoint
- GET /api/calendars- List all calendars

The following MCP tools are registered and available to clients:

⚠️ Permission Warning: TheupdateCalendaranddeleteCalendartools may require special permissions in your Nextcloud instance. Calendar operations are subject to Nextcloud's permission system.

Note: This package is currently in early development (0.1.x). APIs and tools may change without notice in future releases.

- The update and delete calendar operations may require specific permissions in your Nextcloud instance
- Error handling for specific Nextcloud error codes is still being improved
- Large calendars with many events may experience performance issues
