🏈 mcp-server-espn

Enterprise-grade Model Context Protocol (MCP) server for live and historical sports analytics, consensus betting odds, and predictions via ESPN.
Equips AI agents with real-time sports intelligence, live win probabilities, in-depth boxscore statistics, roster hierarchies, and matchup analytics.

[!IMPORTANT] Community Project Disclaimer
mcp-server-espn is an independent open-source community project. It is not affiliated with, sponsored by, endorsed by, or supported by ESPN Inc. or The Walt Disney Company. "ESPN" is a trademark of ESPN Inc. All data provided via ESPN's public REST endpoints is intended for educational, research, and personal non-commercial use.

💡 Why This Exists

Autonomous sports analysis requires high-velocity, structured, and resilient data feeds:

1. Live Game State & Win Probability: Real-time game events (turnovers, scoring plays, pitching changes) shift momentum and expected outcomes dynamically.
2. Key Player Injuries & Depth Chart Swaps: An in-game injury or substitution fundamentally alters team efficiency and tactical matchups.
3. Consensus Odds & Predictive Models: Aggregating consensus sportsbook lines (DraftKings, Caesars, ESPN BET) alongside predictive metrics (FPI, BPI) powers deep statistical game evaluations.

mcp-server-espn provides a unified, hardened Model Context Protocol interface directly to ESPN's public sports data endpoints.

📈 Sports Intelligence Workflows

Workflow 1: Live In-Game Win Probability & Injury Impact

1. Poll Active Games: Agent calls get_scoreboard(sport="football", league="nfl") to identify close games in the 2nd half.
2. Fetch Matchup Predictor & Injuries: Call get_game_summary(sport="football", league="nfl", event_id="401547432") to retrieve ESPN's live win probability curve, consensus spread, and active injury reports.
3. Inspect Player Boxscore Metrics: Use get_player_stats(sport="football", league="nfl", event_id="401547432") to analyze key individual performances (passing yards, completion rates, defensive stops).

Workflow 2: Pre-Game Roster & Depth Chart Matchup Preview

1. Analyze Lineups: Call get_team_depth_chart(sport="baseball", league="mlb", team_id="10") to verify probable starters and positional depth.
2. Review Recent Momentum: Pull get_team_schedule(sport="baseball", league="mlb", team_id="10") and get_standings(sport="baseball", league="mlb") to evaluate streaks and divisional standing.
3. Compare Consensus Betting Lines: Query get_game_summary to evaluate consensus moneyline and over/under spreads across major sportsbooks.
