Check that the ESPN fantasy football HTTP API this server talks to is reachable. Use this first when other tools fail, to tell "API is down" apart from "bad league config".

Get the league id, season year, league name, team count and — most importantly — current_week. Call this before any week-scoped question so you know what "this week" means.

Get league settings: scoring format (PPR / half-PPR / standard and per-stat values), roster and lineup slot counts, playoff team count, playoff week matchup length, waiver/FAAB rules, keeper settings, and divisions. Player value depends entirely on these rules, so read them before ranking, trading or start/sit advice.

List every fantasy team with team_id, name, abbreviation, record (wins/losses/ties), points for, points against and division. Use this to translate a team name the user typed into the numeric teamId other tools require.

Get standings ordered by league rank with wins, losses, ties and points_for. Compare points_for against record to spot lucky and unlucky teams.

Get computed power rankings through a given week. Power score blends scoring and strength of opponents, so it is a better quality estimate than raw record. Use alongside get_standings to explain who is overperforming their record.

Get every draft pick with round, pick number, player, drafting team, auction bid amount and keeper status. Use for draft grades, steal/bust analysis, and to see how much a manager originally invested in a player being discussed in a trade.

Get one team's roster for a specific week: player names, positions, lineup slot (starter vs bench), eligible slots, pro team, injury status and ownership percentages. This is the starting point for start/sit, trade and roster-construction questions. Both teamId and week are required.

Get head-to-head scores for a week: home/away team names, scores and whether the matchup is a playoff game. Safe to call for future weeks, where scores will be zero. For per-player detail use get_box_scores instead.

Get the matchup schedule for a week, including matchup_type (regular season, winners bracket, losers/consolation bracket). Use this to preview who plays whom, including future weeks, and to work out playoff scenarios.

Get detailed box scores for a week: actual and projected team scores plus, with includeLineup, every starter and bench player with their points, projected points, slot, pro opponent, bye-week flag and injury status. This is the richest tool here — use it for start/sit review, bench blunders, over/under-performance versus projection and weekly recaps. Requesting a week later than the league current_week fails with an error, so check get_league first.

List unrostered players available on the waiver wire or as free agents, with projected points and recent points. This is the tool for "who should I pick up", streaming a defense or kicker, and finding a replacement for an injured starter. Filter by position and raise size to see deeper options.

Look up a single player by name or ESPN playerId and get their position, pro team, ownership and start percentages, injury status, and scoring. Use the exact full name ("Patrick Mahomes"); if the lookup fails, find the player via get_free_agents or get_roster and use the returned player_id instead.

Get roster transactions (waiver claims, free-agent adds, drops, trades) for a scoring period, including FAAB bid amounts and whether a claim succeeded or failed. Use this to see what the waiver market paid for a player and which managers are chasing the same needs.

Get the league activity feed — the chronological "who added/dropped/traded what" log. Best tool for "what did I miss this week" and for newsletter or recap writing. Page through with size and offset.

THE tool to call before giving any fantasy advice. Translates the league's raw ESPN settings into plain English: scoring format (PPR value, passing TD value, active yardage bonuses, every scoring rule grouped by category), the exact starting lineup including how many FLEX slots and whether it is superflex, bench and IR slot counts, roster size, waiver and FAAB mechanics, trade deadline, playoff structure, and a list of strategic implications those rules create. Player value depends entirely on these rules, so call this first rather than assuming a standard league.

Audit a team's lineup for a week against the league's real slot requirements and player availability. Detects: unfilled starting slots that would score zero, starters on a bye, starters who are OUT or DOUBTFUL, questionable starters needing a kickoff check, players illegally occupying an IR slot (which blocks lineup submission in ESPN), injured bench players who could be stashed on an open IR slot to free a bench spot, and bench players outscoring a starter they are eligible to replace. Use this for "is my lineup set", "am I missing anything", and IR or bench optimization questions.

Get background on how fantasy football works: the season structure, scoring formats (PPR vs standard), lineup slots, waivers and FAAB, injury designations, strategy vocabulary and league types. Call this when a question uses fantasy jargon you are not confident about, or before giving advice in an unfamiliar league format.

Get the recommended tool sequence for common fantasy questions (start/sit, waiver pickups, trade evaluation, playoff odds, weekly recap, draft review). Call this when you are unsure which tools to combine for a question.
