KenPom Client

A Python API client and MCP server for KenPom basketball analytics. Get direct access to efficiency ratings, game predictions, and advanced stats through Claude or the command line.

Features

  • MCP Server: 11 tools for interactive analysis with Claude

  • Full API Coverage: All 9 KenPom API endpoints

  • Smart Analytics: Matchup comparisons, top team rankings

  • Resilience: Rate limiting, retries, and caching built-in

  • Multi-Format Export: CSV, JSON, and Parquet

Quick Start

cd kenpom-client
uv venv && uv sync
cp .env.example .env  # Add your KENPOM_API_KEY

MCP Server Setup (Claude Code)

The MCP server lets Claude directly query KenPom data during conversations.

Step 1: Project Configuration

The .mcp.json file is already included in this project:

{
  "mcpServers": {
    "kenpom": {
      "command": "uv",
      "args": [
        "--directory",
        "C:/Users/omall/Documents/python_projects/kenpom-client",
        "run",
        "kenpom-mcp"
      ]
    }
  }
}

Step 2: Enable Project MCP Servers

Add this to your Claude Code settings (~/.claude/settings.json):

{
  "enableAllProjectMcpServers": true
}

Or manually approve the server when prompted by Claude Code.

Step 3: Restart Claude Code

Start a new session in the kenpom-client directory. The MCP server will load automatically.

Automated Odds Fetching

The project includes automated scraping of real market odds from overtime.ag for NCAA Basketball games.

Setup

  1. Install Playwright browser:

    uv run playwright install chromium
  2. Add credentials to .env:

    OV_CUSTOMER_ID=your_customer_id
    OV_PASSWORD=your_password
    KENPOM_API_KEY=your_kenpom_api_key

Manual Usage

Fetch current odds and generate predictions:

uv run fetch-odds

This will:

  1. Scrape NCAA Basketball odds from overtime.ag

  2. Save odds to CSV in data/ directory

  3. Automatically generate game predictions using KenPom data

Automated Workflows

A GitHub Actions workflow is available at .github/workflows/odds_workflow.yaml that:

  • Runs daily at 4:00 AM PST (12:00 PM UTC)

  • Fetches odds from overtime.ag

  • Generates KenPom predictions

  • Calculates betting edge

  • Uploads results as artifacts

Setup:

  1. Add GitHub Secrets:

    • OV_CUSTOMER_ID - overtime.ag customer ID

    • OV_PASSWORD - overtime.ag password

    • KENPOM_API_KEY - KenPom API key

  2. The workflow runs automatically on schedule or can be triggered manually via workflow_dispatch

View results:

  • Go to Actions tab in GitHub repository

  • Download artifacts from completed workflow runs

Option 2: Windows Task Scheduler (Local)

For local Windows machines, set up Task Scheduler (runs daily at 4:00 AM PST):

powershell -File setup_task_xml.ps1

The scheduled task runs with automatic retry logic:

  • Retries every 10 minutes if odds not yet available

  • Stops after 2 hours or successful fetch

  • Logs all activity to logs/odds_fetch.log

View logs:

Get-Content logs\odds_fetch.log -Tail 50

Manage task:

# Check status
schtasks /query /tn "FetchOvertimeCollegeBasketballOdds" /fo LIST

# Run manually
Start-ScheduledTask -TaskName 'FetchOvertimeCollegeBasketballOdds'

# Stop task
Stop-ScheduledTask -TaskName 'FetchOvertimeCollegeBasketballOdds'

# Delete task
schtasks /delete /tn "FetchOvertimeCollegeBasketballOdds" /f

Programmatic Usage

from kenpom_client.client import KenPomClient
from kenpom_client.config import Settings

settings = Settings.from_env()
client = KenPomClient(settings)

# Get ratings
ratings = client.ratings(y=2025)
for team in ratings[:5]:
    print(f"{team.TeamName}: AdjEM {team.AdjEM}")

# Get predictions
games = client.fanmatch(d="2024-12-21")
for game in games:
    spread = game.HomePred - game.VisitorPred
    print(f"{game.Visitor} @ {game.Home}: {spread:+.1f}")

# Compare teams
four_factors = client.four_factors(y=2025)
height_data = client.height(y=2025)
misc_stats = client.misc_stats(y=2025)

Automated Validation Hooks

This project uses automated hooks for quality assurance:

  • Pre-commit hook - Validates code before commits (format, lint, type check, tests)

  • Post-edit hook - Type checks after Claude edits files

  • Session start hook - Syncs dependencies on session start

See HOOKS.md for complete documentation.

Manual Commands

uv run ruff format .      # Format
uv run ruff check .       # Lint
pyrefly check             # Type check
uv run pytest             # Test

# Full validation (what pre-commit runs)
