git clone https://github.com/mvilanova/intervals-mcp-server.git
cd intervals-mcp-server

5. Set up environment variables

Make a copy of .env.example and name it .env by running the following command:

cp .env.example .env

Then edit the .env file and set your Intervals.icu athlete id and API key:

API_KEY=your_intervals_api_key_here
ATHLETE_ID=your_athlete_id_here

Getting your Intervals.icu API Key

1. Log in to your Intervals.icu account
2. Go to Settings > API
3. Generate a new API key

Finding your Athlete ID

Your athlete ID is typically visible in the URL when you’re logged into Intervals.icu. It looks like:

• https://intervals.icu/athlete/i12345/... where i12345 is your athlete ID

Usage

1. Configure Claude Desktop

To use this server with Claude Desktop, you need to add it to your Claude Desktop configuration.

1. Run the following from the intervals_mcp_server directory to configure Claude Desktop:

mcp install src/intervals_mcp_server/server.py --name "Intervals.icu MCP Server"

2. If you open your Claude Desktop App configuration file claude_desktop_config.json, it should look like this:

{
  "mcpServers": {
    "Intervals.icu": {
      "command": "uv",
      "args": [
        "run",
        "--with",
        "mcp[cli]",
        "mcp",
        "run",
        "/path/to/intervals-mcp-server/src/intervals_mcp_server/server.py"
      ]
    }
  }
}

Where /path/to/ is the path to the intervals-mcp-server code folder in your system.

3. Restart Claude Desktop.
