EuroLeague Analytics MCP
Model Context Protocol for Basketball Intelligence

Validated EuroLeague & EuroCup Analytics for AI Models

Not an API wrapper. A precision derived layer reconstructing exact possessions, four factors, five-man lineup on/off splits, and court shot charts from public play-by-play event streams.

The Derived Analytics Layer

Moving beyond box-score approximations to exact play-by-play event reconstruction.

⊕

Exact Possession Accounting

Traditional box score formulas (like FGA - ORB + TO + 0.44*FTA) are crude estimates. Possessions are counted directly from the event stream across five verified possession-ending criteria, preserving offensive rebound continuations and dead-ball technical free throws.

⧉

5-Man Lineup Reconstruction

Tracks substitution batches dynamically to maintain exactly five players on court at all times. Reconstructs matchup stints, lineup offensive/defensive ratings, net ratings, and on/off player impact splits.

⌖

Court Shot Coordinates

Merges coordinate sources with play-by-play event attempts, allowing models to filter shot locations by lineup unit, clutch time remaining, and game margin.

&clock;

Dynamic Clutch Filters

Clutch is stored as margin_at_start and seconds_remaining_at_start on each possession rather than a hard-coded table. Query any clutch definition (e.g. final 2 minutes ±3 points or final 5 minutes ±5 points) on the fly.

&shield;

Honest Data Integrity

When source data contains unresolvable clock anomalies or recording errors, games are explicitly quarantined (e.g. possession_gate) and disclosed in every response, never smoothed over with synthetic data.
