Workout MCP Server

A Model Context Protocol (MCP) server that provides cycling workout analytics tools, enabling LLMs to analyze fitness data, calculate training metrics, and provide insights into athletic performance.

Features

The Workout MCP Server provides tools for:

• Retrieving workout history (last 50 or last 7 workouts)
• Looking up specific workouts by ID
• Computing fitness metrics:
  • Fitness (CTL): Chronic Training Load - 42-day exponentially weighted moving average
  • Fatigue (ATL): Acute Training Load - 7-day exponentially weighted moving average
  • Form (TSB): Training Stress Balance - the difference between fitness and fatigue

Installation

Using uv (recommended)

When using uv no specific installation is needed. We will use uvx to directly run workout_mcp_server.

Using PIP

Alternatively you can install workout_mcp_server via pip:

pip install workout_mcp_server

After installation, you can run it as a module using:

python -m workout_mcp_server

Configuration

Configure with Claude Desktop

Add this to your claude_desktop_config.json:

"mcpServers": {
  "workout_mcp_server": {
    "command": "uvx",
    "args": ["workout_mcp_server"]
  }
}

"mcpServers": {
  "workout_mcp_server": {
    "command": "python",
    "args": ["-m", "workout_mcp_server"]
  }
}

Configure with VSCode MCP Client

Add this to your settings.json:

"mcp.servers": {
  "workout_mcp_server": {
    "command": "uvx",
    "args": ["workout_mcp_server"]
  }
}

"mcp.servers": {
  "workout_mcp_server": {
    "command": "python",
    "args": ["-m", "workout_mcp_server"]
  }
}

Available Tools

get_last_50_workouts

Retrieves all 50 workouts from the dataset, sorted by date (most recent first).

get_last_7_workouts

Retrieves the 7 most recent workouts, useful for analyzing current training week.

get_workout_by_id

Retrieves a specific workout by its unique ID.

Input:

• workout_id (string): The unique identifier of the workout

compute_fitness

Calculates current fitness score (Chronic Training Load) based on a 42-day exponentially weighted moving average of Training Stress Score (TSS).

compute_fatigue

Calculates current fatigue score (Acute Training Load) based on a 7-day exponentially weighted moving average of TSS.

compute_form

Calculates current form score (Training Stress Balance) as the difference between fitness and fatigue. Positive values indicate good form, negative values suggest accumulated fatigue.

Data Structure

Each workout contains:

• id: Unique workout identifier
• date: Workout date (ISO format)
• duration_minutes: Workout duration in minutes
• distance_km: Distance covered in kilometers
• avg_power_watts: Average power output in watts
• tss: Training Stress Score
• workout_type: Type of workout (e.g., "endurance", "interval", "recovery")
