Intervals MCP服务器

Requirements

• Python 3.12 or higher
• Model Context Protocol (MCP) Python SDK
• httpx
• python-dotenv

4. Sync project dependencies

uv sync

2. Update Python dependencies

Activate your virtual environment and sync dependencies:

macOS/Linux:

source .venv/bin/activate
uv sync

Windows (PowerShell):

.venv\Scripts\activate
uv sync

Setup

1. Install uv (recommended)

macOS/Linux:

curl -LsSf https://astral.sh/uv/install.sh | sh

Windows (PowerShell):

powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

After installation, find the full path to uv — you'll need it later when configuring Claude Desktop:

```powershell where.exe uv

Example output: C:\Users\<USERNAME>\.local\bin\uv.exe

```

Usage with Claude

Usage with ChatGPT

ChatGPT’s beta MCP connectors can also talk to this server over the SSE transport.

1. Start the server in SSE mode so it exposes the /sse and /messages/ endpoints:

   export FASTMCP_HOST=127.0.0.1 FASTMCP_PORT=8765 MCP_TRANSPORT=sse FASTMCP_LOG_LEVEL=INFO
   python src/intervals_mcp_server/server.py
   

The startup log prints the full URLs (for example http://127.0.0.1:8765/sse). ChatGPT needs that public URL, so forward the port with a tool such as ngrok http 8765 if you are not exposing the server directly.

1. In ChatGPT, open Settings → Features → Custom MCP Connectors and click Add. Fill in:

• Name: Intervals.icu
• MCP Server URL: https://<your-public-host>/sse
• Authentication: leave as No authentication unless you have protected your tunnel.

You can reuse the same ngrok http 8765 tunnel URL here; just ensure it forwards to the host/port you exported above.

1. Save the connector and open a new chat. ChatGPT will keep the SSE connection open and POST follow-up requests to the /messages/ endpoint announced by the server. If you restart the MCP server or tunnel, rerun the SSE command and update the connector URL if it changes.

3. Create and activate a virtual environment

```bash

Create virtual environment with Python 3.12

uv venv --python 3.12

Activate virtual environment

5. Set up environment variables

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

macOS/Linux:

cp .env.example .env

Windows (PowerShell):

Copy-Item .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

1. Configure Claude Desktop

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

macOS/Linux

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" --with-editable . --env-file .env

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

{
  "mcpServers": {
    "Intervals.icu": {
      "command": "/Users/<USERNAME>/.local/bin/uv",
      "args": [
        "run",
        "--with",
        "mcp[cli]",
        "--with-editable",
        "/path/to/intervals-mcp-server",
        "mcp",
        "run",
        "/path/to/intervals-mcp-server/src/intervals_mcp_server/server.py"
      ],
      "env": {
        "INTERVALS_API_BASE_URL": "https://intervals.icu/api/v1",
        "ATHLETE_ID": "<YOUR_ATHLETE_ID>",
        "API_KEY": "<YOUR_API_KEY>",
        "LOG_LEVEL": "INFO"
      }
    }
  }
}

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

Windows

The mcp install command may fail on Windows due to environment or permission issues. Instead, configure Claude Desktop manually:

1. Find the Claude Desktop config file. If Claude Desktop was installed from the Microsoft Store, the config is located at:

   C:\Users\<USERNAME>\AppData\Local\Packages\Claude_pzs8sxrjxfjjc\LocalCache\Roaming\Claude\claude_desktop_config.json
   

If installed via the standard installer, it may be at:

   C:\Users\<USERNAME>\AppData\Roaming\Claude\claude_desktop_config.json
   

If the file or folder does not exist, create it.

1. Add the following entry to claude_desktop_config.json, replacing the placeholders with your actual values:

{
  "mcpServers": {
    "Intervals.icu": {
      "command": "C:\\Users\\<USERNAME>\\.local\\bin\\uv.exe",
      "args": [
        "run",
        "--with",
        "mcp[cli]",
        "--with-editable",
        "C:\\path\\to\\intervals-mcp-server",
        "mcp",
        "run",
        "C:\\path\\to\\intervals-mcp-server\\src\\intervals_mcp_server\\server.py"
      ],
      "env": {
        "INTERVALS_API_BASE_URL": "https://intervals.icu/api/v1",
        "ATHLETE_ID": "<YOUR_ATHLETE_ID>",
        "API_KEY": "<YOUR_API_KEY>",
        "LOG_LEVEL": "INFO"
      }
    }
  }
}

• Use double backslashes (\\) for all Windows paths in JSON.
• To find the full path to uv.exe, run where.exe uv in PowerShell.
• To find the full path to the cloned repository, run pwd from inside the intervals-mcp-server folder.

Note for Windows Store installs: Claude Desktop installed from the Microsoft Store sandboxes its config under AppData\Local\Packages\.... Editing AppData\Roaming\Claude\claude_desktop_config.json will have no effect — make sure you edit the correct file.

1. Restart Claude Desktop.

Troubleshooting

If Claude Desktop fails due to configuration changes, follow these steps:

1. Delete the existing Intervals.icu entry in claude_desktop_config.json.
2. Reconfigure Claude Desktop from the intervals-mcp-server directory.

macOS/Linux:

mcp install src/intervals_mcp_server/server.py --name "Intervals.icu" --with-editable . --env-file .env

Windows: Re-add the entry manually as described in the Windows configuration section.

Common errors

spawn uv ENOENT — Claude Desktop cannot find the uv executable. Use the full path to uv in the command field. Run which uv (macOS/Linux) or where.exe uv (Windows) to get it.

spawn /Users/... ENOENT on Windows — The config file contains a macOS/Linux-style path. Replace it with the correct Windows path using backslashes as described in the Windows configuration section below.

Windows Store install: config changes not taking effect — You may be editing the wrong config file. Claude Desktop installed from the Microsoft Store reads from AppData\Local\Packages\Claude_pzs8sxrjxfjjc\LocalCache\Roaming\Claude\claude_desktop_config.json, not AppData\Roaming\Claude\.
