Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
player
get_player
Returns one player's profile by id: name, team, position, injury status, jersey and cross-system ids, plus per-season data on Basic and above. Use it to check a player's current team or injury status. Free plan (profile fields only; season data needs Basic).
get_player_by_espn_id
Returns the player whose ESPN athlete id this is (the numeric id ESPN and many sportsbook feeds use), as the same record get_player returns. Use it to join ESPN or sportsbook data to GridIron player ids. Free plan.
get_player_by_gsis_id
Returns the player with this NFL GSIS id (e.g. "00-0034857", the key nflverse and NFL data use), as the same record get_player returns, with an ids map (gsis, pfr, pff, nfl, espn, sleeper) from the daily nflverse crosswalk. Use it to join nflverse or NFL data to GridIron. Free plan.
get_player_news
Returns recent news headlines for one player, newest first, each tagged by impact (injury, role, transaction or general). Use it for "any news on X?" and injury or role questions about a specific player; for the whole league use get_latest_news. Basic plan and above.
get_player_stats
Returns a player's actual stats for one season (2020 to now): fantasy points week by week and in total in the chosen scoring, plus the raw stat line and snap share each week. Use it for "how did X do" questions, game logs and comparisons with projections. Basic plan and above.
players
list_players
Returns a page of NFL players (player_id, name, position, team), optionally for one position, paged with next_cursor. Use it to browse a position group; to find a specific player, search_players is faster. Free plan.
search_players
Finds players by full or partial name (case-insensitive) and returns each match's exact player_id ("First Last#POS"), team and position. Use it first whenever you have a name but not the id the other tools need. Defenses match by team code or nickname too ("TB", "Bucs", "Tampa Bay DST"). Free plan.
byes
get_byes
Returns every team's bye week for a season, and the teams on bye each week. Use it to plan lineups and spot bye-week holes on a roster. Basic plan and above.
defense
get_defense_vs_position
Returns what each NFL defense allows per game to QBs, RBs, WRs or TEs: fantasy points plus yards, TDs, receptions and targets, from ESPN box scores, ranked so rank 1 allows the most (the best matchup). Use it for matchup-based start/sit and streaming, optionally over the last N weeks. Pro plan (Free and Basic keys get 403 pro_required).
depth
get_depth_chart
Returns NFL depth charts as of the daily nflverse refresh (as_of), for one team or all 32, optionally one position or group (CB, LB, EDGE, ...) or starters only. Each entry has the player, ids, position, formation, slot, depth within the slot (1 = starter), a starter flag, and the player's current injury_status and available, so an OUT or IR starter is flagged rather than moved. Use it for "who are the Bears' starting WRs?" or the next man up behind an injured player. Built from ESPN's public depth charts via nflverse, not official team depth charts. Pro plan (Free and Basic keys get 403 pro_required).
deviations
get_deviations
Returns how a player's actual fantasy points compared with his projections: the average deviation and each week's projected vs actual. Use it to judge boom/bust tendencies or whether a player keeps beating (or missing) his projection. Basic plan and above.
inactives
get_inactives
Returns the NFL's official game-day inactives for a week (default the newest week published), by team, with gsis, espn, sleeper and pfr ids. Published after the games, usually days later. Use it for audits and backtesting, not as a pre-kickoff list (teams_published vs teams_played shows how complete the week is). Pro plan (Free and Basic keys get 403 pro_required).
injury
get_injury_changes
Returns players whose injury status changed since a time (default the last 24 hours, up to 14 days back), with previous_status, status and detected_at. Statuses are checked against ESPN every 2 minutes from 8am to 1am ET. Use it for "who got hurt or cleared today?" and game-day checks; pass next_since back as since to get only newer changes. Pro plan (Free and Basic keys get 403 pro_required).
latest
get_latest_news
Returns the league-wide NFL news feed across every tracked player, newest first: signings, trades, cuts, injuries and depth-chart moves, filterable by time, impact, position and team, paged with next_cursor. Use it for "what happened today/this week" or a team's or position's latest news. Basic plan and above.
matchups
get_matchups
Returns a player's past games and fantasy points against one opponent. Use it for matchup questions like "how does he do against KC?". Basic plan and above.
projections
get_projections
Returns projected fantasy points for every player in an NFL week (1-18), in PPR, half-PPR or standard scoring, optionally for one position or team. Use it for start/sit, rankings and "top N at a position this week". Each row also has gridiron_projection, GridIron Data's own model (with model_version and as_of; null when none), which unlike projected_points may be displayed under Pro + Commercial. Players who can't play project 0 with available=false. Free plan: the current week of the current season; other weeks and seasons need Basic; Pro adds projected_stats per row (pass_yds, rec, rush_yds, ...).
prop
get_prop_probability
Returns the probability a player goes over or under a stat line (passing, rushing or receiving yards, TDs, attempts, completions, interceptions, receptions), with fair no-vig American odds for each side, the projected mean and spread, the week's game and betting line, and the model's backtest. Use it to price a player prop or compare a sportsbook line with a fair price. Players on bye or OUT/IR get p_over 0. Model estimate, not betting advice. Pro plan (Free and Basic keys get 403 pro_required).
request
request_news_scrape
Queues an on-demand news pull for a player who has no news coverage yet and returns at once (202); the headlines appear in get_player_news shortly after. Use it only when get_player_news comes back empty. Asking twice is harmless. Basic plan and above.
ros
get_ros_projections
Returns each player's projected fantasy points for the rest of the current season (weeks already played and his bye are skipped), with games_remaining and points_per_game. Use it for trades, waiver pickups and dynasty or keeper decisions. Filter by position, team or one player. Basic plan and above.
schedule
get_schedule
Returns the NFL regular-season schedule: week, home and away teams, kickoff time (UTC), status and final score, for a season, one week or one team (with that team's bye week). Use it for "who plays whom", kickoff times and results. Basic plan and above; Pro keys also get each game's betting line (spread_home, over_under, moneylines, implied team points).
snap
get_snap_share
Returns a player's offensive snap share each week (the % of his team's offensive plays he was on the field for), the season average, and a trailing average with its change vs the season. Use it to spot role changes before they show in the box score (a committee back taking over, a rookie WR passing a veteran). Seasons 2020-2026, current season updated weekly. Basic plan and above.

GridIron Data — questions
Answers built from our own checks of this server.
What can GridIron Data do?
It exposes 21 tools, read directly from the server on our last check. Among them: get_byes, get_defense_vs_position, get_depth_chart, get_deviations, get_inactives, get_injury_changes and 15 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
What is GridIron Data mostly used for?
Its tools cluster around player and players. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is GridIron Data working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 1408 ms. The bar chart above shows every period we have measured.
How do I connect GridIron Data?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does GridIron Data need an API key?
No. GridIron Data completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 21 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is GridIron Data?
It answers our handshake in 1408 ms on average, which is faster than 1% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
