Weather MCP server

The MCP Weather Server is a specialized server that implements the Model Context Protocol to provide weather information for different cities. It leverages the Open-Meteo API to fetch and deliver current weather data when requested through compatible MCP clients.

Installation

You can install the MCP Weather Server using pip:

pip install mcp_weather_server

After installation, you need to configure the server in your MCP settings file:

1. Open or create your cline_mcp_settings.json file
2. Add the following configuration to the mcpServers object:

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

3. Save the settings file

Usage

The MCP Weather Server provides a single tool called get_weather that retrieves current weather information for a specified city.

Getting Weather Information

To retrieve weather data, use the get_weather tool with a city name parameter.

Parameters:

• city (string, required): The name of the city you want weather information for

Example usage:

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

The server will return current weather conditions for the specified city using data from the Open-Meteo API. No API key is required to use this service, as the Open-Meteo API is free and open-source.

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.
