Weather MCP server

The Weather MCP Server provides weather information through the Model Context Protocol, leveraging the Open-Meteo API to deliver current and historical weather data for specified locations without requiring an API key.

Installation

You can install the Weather MCP Server using pip:

pip install mcp_weather_server

After installation, you need to configure it in your cline_mcp_settings.json file:

1. Add the following entry to the mcpServers object:

{
  "mcpServers": {
    "weather": {
      "command": "python",
      "args": [
        "-m",
        "mcp_weather_server"
      ],
      "disabled": false,
      "autoApprove": []
    }
  }
}

2. Save the cline_mcp_settings.json file.

Usage

The Weather MCP Server provides three main tools for accessing weather information.

Getting Current Weather

To retrieve current weather information for a specific city, use the get_weather tool:

<use_mcp_tool>
<server_name>weather</server_name>
<tool_name>get_weather</tool_name>
<arguments>
{
  "city": "Taipei"
}
</arguments>
</use_mcp_tool>

Getting Weather for a Date Range

To retrieve weather information for a specific date range, use the get_weather_by_datetime_range tool:

<use_mcp_tool>
<server_name>weather</server_name>
<tool_name>get_weather_by_datetime_range</tool_name>
<arguments>
{
  "city": "London",
  "start_date": "2024-01-01",
  "end_date": "2024-01-07"
}
</arguments>
</use_mcp_tool>

Getting Current Date and Time

To get the current time in a specific timezone, use the get_current_datetime tool:

<use_mcp_tool>
<server_name>weather</server_name>
<tool_name>get_current_datetime</tool_name>
<arguments>
{
  "timezone_name": "America/New_York"
}
</arguments>
</use_mcp_tool>

If no timezone is specified, UTC will be used as the default.

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.
