nfl-mcp

MCP server for NFL play-by-play data (2013–2025), powered by nflreadpy and DuckDB. Query 13 seasons of NFL play-by-play data using natural language in Claude Code, VS Code, or Claude Desktop.

Ask Claude questions like:

• "Who had the best EPA per play in 2024?"
• "Show me Patrick Mahomes' completion % over expected by season"
• "Compare 4th quarter red zone efficiency for KC vs PHI in 2023"
• "Which defenses had the highest sack rate in 3rd & long situations?"

Quickstart

pip install nfl-mcp        # or: uvx nfl-mcp
nfl-mcp init               # defaults to all 13 seasons (2013–2025) + IDE setup

No database server to install. No credentials to manage. Data is stored locally in DuckDB.

Prerequisites

• Python 3.10+
• uv (recommended) or pip

Setup

1. Initialize

nfl-mcp init

The wizard will:

1. Configure the local DuckDB database path
2. Download NFL play-by-play data for all 13 seasons by default (2013–2025)
3. Auto-configure your IDE (Claude Desktop and/or VS Code)

Options:

--start 2020        First season (default: 2013)
--end   2024        Last season  (default: 2025)
--skip-ingest       Configure without loading data

--start must be less than or equal to --end. With no flags, nfl-mcp init loads all seasons from 2013 through 2025.

2. Verify

nfl-mcp doctor

Checks database connectivity, loaded data, and IDE configuration.

3. Manual client configuration (optional)

If you skipped IDE setup during init, or need to reconfigure:

nfl-mcp setup-client                    # auto-detect clients
nfl-mcp setup-client --client vscode    # VS Code only
nfl-mcp setup-client --client claude-desktop

Or configure manually — add to .vscode/mcp.json:

{
  "servers": {
    "nfl": {
      "command": "uvx",
      "args": ["nfl-mcp", "serve"]
    }
  }
}

Tools

Database Schema

Hundreds of thousands of plays across 2013–2025, with 370+ nflreadpy columns preserved as-is.

Key tables:

• plays — every play, all columns
• team_offense_stats — pre-aggregated by team/season
• team_defense_stats — pre-aggregated by team/season
• situational_stats — by team/season/situation (Red Zone, 3rd & Long, etc.)
• formation_effectiveness — by team/season/formation

Key columns:

• epa — expected points added (the best single-play quality metric)
• wpa — win probability added
• posteam / defteam — offensive/defensive team abbreviations
• passer_player_name / rusher_player_name / receiver_player_name
• play_type — 'pass' | 'run' | 'field_goal' | 'punt' | 'kickoff' | ...
• desc — raw play description (use ILIKE for text search)

Local Development

git clone https://github.com/ebhattad/nfl-mcp
cd nfl-mcp
pip install -e ".[dev]"

nfl-mcp init --start 2024 --end 2024
pytest

Troubleshooting

• nfl-mcp doctor is the fastest way to verify config, database, and client setup.
• If tools return database errors, run nfl-mcp ingest (or rerun nfl-mcp init) to ensure plays is loaded.
• You can override the DB location with NFL_MCP_DB_PATH=/path/to/nflread.duckdb.
