Usage

Creating Calendar Events

You can create Google Calendar events with customizable parameters:

from GoogleCalendarMCP.main import create_event

# Create a calendar event
result = await create_event(
    summary="Meeting with Team",
    start_time="2025-04-01T10:00:00",
    end_time="2025-04-01T11:00:00",
    description="Discuss project progress",
    location="Conference Room 3",
    attendees=["[email protected]"],
    timezone="America/New_York"
)

Parameters

The create_event function accepts the following parameters:

• summary: The title of the event
• start_time: Event start time in ISO format (YYYY-MM-DDTHH:MM:SS)
• end_time: Event end time in ISO format (YYYY-MM-DDTHH:MM:SS)
• description: Optional detailed description of the event
• location: Optional location where the event will take place
• attendees: Optional list of email addresses for attendees
• timezone: Optional timezone identifier (default: "America/New_York")

Authentication

The first time you run the program, it will open a browser window prompting you to authenticate with your Google account. After successful authentication, a token.json file will be created in your project directory to store your credentials. This allows the application to make API calls on your behalf without requiring re-authentication for subsequent runs.

How to add this MCP server to Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > MCP and click "Add new global MCP server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
