| Name | Description | Schema |
|---|---|---|
get_current_insights | 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. | typed |
query_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. Takes a verified panel metric key. | typed |
get_entity_metrics | The verified figures 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. By default the headline figures | typed |
compare_entities | Two players or two teams shown side by side — by default on the metrics that matter for their position, on named metrics when `metrics` is set, and on the full set with all:true. Each side carries its | typed |
get_metric_definition | Muffed's published definition of a verified metric — what it measures, in plain language, from the glossary page for that term — plus which seasons it actually covers, how it is ranked, its licence an | typed |
list_metrics | What Muffed can answer on. By default a summary of metric families with their counts and season coverage; with search or detail:true, individual metric keys. Returns keys and coverage only, never figu | typed |
search_metrics | The verified metrics that match a topic — e.g. 'screens', 'blitz', 'time to throw' — ranked by a text match over each metric's key, label, common names and board description. Up to 20 entries, each wi | typed |
verify_claim | 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 fie | typed |
get_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. | typed |
run_stat_query | Computes an NFL figure from a structured query rather than looking one up: a population (position, qualifying threshold), a window (seasons, weeks, a team span, a coach's tenure), one named measure, a | incomplete |
sleeper_find_leagues | Lists the NFL leagues a Sleeper username belongs to, with each league's id. Muffed stores nothing about the requester. | typed |
sleeper_get_league | One league's name, season, size, current week, detected scoring format, and the manager-to-roster map. | typed |
sleeper_matchup_preview | 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. | typed |
sleeper_roster_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. | typed |
sleeper_standings_story | 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. | typed |
