AEMET (Spain's Meteorological Agency) MCP server for AI agents

Aemet-mcp is a server that integrates with the AEMET (Spain's State Meteorological Agency) API using the Model Context Protocol (MCP). It allows AI assistants like Claude to access historical climate data, weather information, and meteorological measurements from weather stations across Spain.

Installation Options

Installing via Smithery

For a quick automated installation:

npx -y @smithery/cli install @AnCode666/aemet-mcp --client claude

Installing with uv

Prerequisites

Python 3.10 or higher

Configuring with Claude Desktop

Go to Claude > Settings > Developer > Edit Config > claude_desktop_config.json
Add the following block inside the "mcpServers" section:

"aemet_mcp_": {
    "command": "uvx",
    "args": [
        "aemet_mcp"
    ],
    "env": {
        "AEMET_API_KEY": "YOUR_AEMET_API_KEY"
    }
}

Get a free API key from AEMET at: https://opendata.aemet.es/centrodedescargas/altaUsuario
Replace YOUR_AEMET_API_KEY with your actual API key (keep the quotes)
If you have other MCP servers configured, separate each block with a comma ,

Integrating with Other MCP Clients

For other MCP-compatible clients like Cursor, CODEGPT, or Roo Code, locate the MCP server configuration section in your client settings and add the same code block as shown above.

Usage Examples

Once configured, you can ask questions such as:

"What's the weather like in Seville?"
"Give me a list of the beaches in the province of Málaga"
"Tell me the radiation levels at Maspalomas beach for tomorrow"
"Give me the historical rainfall data for Albacete between January 1st, 2020 and February 1st, 2020"
"Give me a list of the weather stations within a 50 km radius from the coordinates lat:40.4165, lon:-3.70256"

Features

The MCP server provides access to:

Historical daily weather values (temperature, wind, precipitation, etc.)
Monthly climate summaries by station
Data filtering by year, month, and AEMET station code
Beach conditions and ultraviolet radiation indices
Responses in ready-to-use JSON format

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "aemet_mcp_" '{"command":"uvx","args":["aemet_mcp"],"env":{"AEMET_API_KEY":"YOUR_AEMET_API_KEY"}}'

See the official Claude Code MCP documentation for more details.

For 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 > Tools & Integrations and click "New MCP Server".

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

{
    "mcpServers": {
        "aemet_mcp_": {
            "command": "uvx",
            "args": [
                "aemet_mcp"
            ],
            "env": {
                "AEMET_API_KEY": "YOUR_AEMET_API_KEY"
            }
        }
    }
}

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 explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json
Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "aemet_mcp_": {
            "command": "uvx",
            "args": [
                "aemet_mcp"
            ],
            "env": {
                "AEMET_API_KEY": "YOUR_AEMET_API_KEY"
            }
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
