How to install it

It runs on your machine and needs Node.js. Configuration taken from the official MCP registry.

In a terminal:

claude mcp add --env CALDAV_BASE_URL=YOUR_VALUE --env CALDAV_USERNAME=YOUR_VALUE --env CALDAV_PASSWORD=YOUR_VALUE --transport stdio caldav-mcp -- npx -y caldav-mcp

In ~/.cursor/mcp.json (or .cursor/mcp.json in your project):

{
    "mcpServers": {
        "caldav-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "caldav-mcp"
            ],
            "env": {
                "CALDAV_BASE_URL": "YOUR_VALUE",
                "CALDAV_USERNAME": "YOUR_VALUE",
                "CALDAV_PASSWORD": "YOUR_VALUE"
            }
        }
    }
}

If the file already lists other servers, add only this entry inside the list.

In your project's .vscode/mcp.json:

{
    "servers": {
        "caldav-mcp": {
            "type": "stdio",
            "command": "npx",
            "args": [
                "-y",
                "caldav-mcp"
            ],
            "env": {
                "CALDAV_BASE_URL": "YOUR_VALUE",
                "CALDAV_USERNAME": "YOUR_VALUE",
                "CALDAV_PASSWORD": "YOUR_VALUE"
            }
        }
    }
}

If the file already lists other servers, add only this entry inside the list.

In claude_desktop_config.json (macOS: ~/Library/Application Support/Claude; Windows: %APPDATA%\Claude), then restart Claude:

{
    "mcpServers": {
        "caldav-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "caldav-mcp"
            ],
            "env": {
                "CALDAV_BASE_URL": "YOUR_VALUE",
                "CALDAV_USERNAME": "YOUR_VALUE",
                "CALDAV_PASSWORD": "YOUR_VALUE"
            }
        }
    }
}

If the file already lists other servers, add only this entry inside the list.

Replace YOUR_VALUE with your keys, and do not commit the file with them to a repository.
