## Tools
- get_current_insights (Muffed's current reads) - Muffed's published editorial reads on what is real in the NFL right now — each one a dated, sourced claim with its supporting figures, from the /trends board. Endpoint: https://muffed.ai/api/mcp
- query_stat_leaders (Verified stat leaders) - Top entities on one verified metric for one season, pre-sorted, each with the source's own rank and the population it was ranked against. Call list_metrics for the metric keys this accepts. Endpoint: https://muffed.ai/api/mcp
- get_entity_metrics (A player's or team's verified figures) - Every verified figure Muffed holds for one NFL player or one NFL team (by name or abbreviation, e.g. "Bijan Robinson" or "DEN"), with the source's rank where one exists. Names are resolved before lookup; an unrecognised name returns the closest matches rather than a guess. Endpoint: https://muffed.ai/api/mcp
- compare_entities (Compare two players or teams) - Two players or two teams shown side by side on the verified metrics both have, with each side's source rank. States both figures and stops: it names no winner, no margin and no recommendation. Endpoint: https://muffed.ai/api/mcp
- get_metric_definition (What a metric means) - What a verified metric measures, which seasons it actually covers, how it is ranked, its licence and its attribution. Season coverage is often narrower than a decade — rushing yards over expectation, for instance, exists from 2018 onward. Endpoint: https://muffed.ai/api/mcp
- list_metrics (List verified metrics) - The metric keys Muffed can answer on, with their labels and the seasons each one covers. Returns keys and coverage only, never figures. Endpoint: https://muffed.ai/api/mcp
- verify_claim (Check a stated figure against Muffed) - Checks structured claims against Muffed's verified panel. Each claim comes back confirmed, wrong (with the actual value), or unverifiable (with the metric's real season coverage). Takes structured fields only, not sentences. Endpoint: https://muffed.ai/api/mcp
- get_backfield (A team's backfield) - Muffed's published handcuff page for one team's backfield, plus the current depth chart and injury status from Sleeper. Answers who backs up a starter, and who replaces one who is out. Endpoint: https://muffed.ai/api/mcp
- sleeper_find_leagues (Find a Sleeper user's leagues) - Lists the NFL leagues a Sleeper username belongs to, so a league id can be picked for the other league tools. Muffed stores nothing about who called it. Endpoint: https://muffed.ai/api/mcp
- sleeper_get_league (A Sleeper league's setup) - One league's name, season, size, current week, detected scoring format, and the manager-to-roster map. Everything downstream reads better once this has been called. Endpoint: https://muffed.ai/api/mcp
- sleeper_matchup_preview (Verified context for a matchup) - Both sides of a league matchup, with the verified figures Muffed holds for the players involved and each team's record. Muffed does not project outcomes, name a winner, or recommend a lineup. Endpoint: https://muffed.ai/api/mcp
- sleeper_roster_stories (A roster's verified stories) - One team's roster mapped to the verified figures and published Muffed surfaces for each player. Players Muffed does not cover are listed as uncovered rather than omitted. Endpoint: https://muffed.ai/api/mcp
- sleeper_standings_story (A league's standings) - League standings derived from Sleeper's roster settings — records, points for, and points against where available. Sleeper publishes no standings endpoint, so these are computed from the roster rows. Endpoint: https://muffed.ai/api/mcp
