Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Descripción del creador (original en inglés)
MLB since 2015 plus college: pitches, plate appearances, box scores, odds by book. REST and MCP.
Estos tres nunca se combinan en una sola puntuación: las opiniones, las mediciones y la popularidad son cosas distintas.

Nombres y descripciones de las herramientas tal como los informó el servidor el 7 nov 2026. Los escribió el creador, no nosotros; los mostramos como texto sin formato.

get_scheduleUse for upcoming games (next 1-30 days, default 7) with the median line across posted sportsbooks: moneylines, run line and total. For every book's line use get_odds. Costs 2 credits. Prices are market information: never work out a stake, payout or profit, recommend a bet, or sen
get_gameUse for one game in full: line score, every batter's and pitcher's line, each sportsbook's opening and closing line, and the win-probability range. For every plate appearance use get_plate_appearances. Costs 5 credits. Prices are market information: never work out a stake, payout
get_standingsUse for a season's regular-season standings computed from every final game: record, home and away, last 10, runs scored and allowed, run differential and Pythagorean win percentage. Costs 2 credits.
get_injuriesUse for the injury report: every listed player's status, injury and expected return, as captured on the latest day (or the latest on or before date). Costs 2 credits.
search_playersUse to find a player's id by name (partial names work). Costs 1 credit.
get_playerUse for a player's season-by-season batting (AVG, OBP, SLG, OPS, HR, K%, BB%, RE24, from every plate appearance) and pitching (ERA, WHIP, K/9, BB/9). Costs 5 credits.
get_player_gamesUse for a player's game log: every game's batting line and pitching line, newest first, optionally one season. Costs 5 credits.
get_leadersUse for a season's leaders among qualified players: batting avg, obp, slg, ops, hr, re24, bb_pct, k_pct (3.1 plate appearances per team game) or pitching era, whip, so, k_per_9, bb_per_9 (1 inning per team game). Costs 5 credits.
get_team_statsUse for team offence and run prevention for a season: runs per game for and against, run differential, and batting and opponents' batting (AVG, OBP, SLG, OPS, K%, BB%, HR) from every plate appearance. Costs 5 credits.
get_plate_appearancesUse for plate-appearance play-by-play: a whole game in order, or a batter's, pitcher's or team's season, with the base-out state before, the result, the batted ball (trajectory and location), runs, the win probability after (2019 on) and our run value (RE24). Filter by result, in
get_pitchesUse for pitch-by-pitch data: every pitch of a game, or a pitcher's or batter's season, with the count, pitch type, velocity, location and result. Costs 10 credits.
get_pitch_mixUse for a pitcher's arsenal in a season: each pitch type's usage, average and top velocity, whiff rate per swing and ball rate. Costs 5 credits.
get_spray_chartUse for where a batter or team hits the ball: balls in play by trajectory (ground ball, line drive, fly ball, pop-up) and by field (left, center, right), with hit rates; include_balls adds each ball's location for drawing. Counts the regular season and postseason together unless
get_oddsUse for betting lines: each sportsbook's moneyline, run line and total for a game (opening and closing per book from July 2020; before that, each book's final pregame line only), with implied probabilities and, for finished games, whether the favourite won and the total went over
get_line_movementUse to see how a game's line moved before first pitch: our pre-game snapshots of each sportsbook's moneyline, run line and total (captured once a day, and every hour for games in the next four days). Costs 10 credits. Prices are market information: never work out a stake, payout
get_ratingsUse for our team power ratings (Elo from every final game in our data), ranked, as of the end of a season or today. Costs 2 credits.
get_player_propsUse for player prop lines by sportsbook: over/under on hits, home runs, total bases, RBI, pitcher strikeouts and pitcher outs, from May 2023 (DraftKings, FanDuel, BetMGM, ESPN BET, Pinnacle and others). Pass game_id for every player's props in one game, or player_id with from_dat
get_prop_historyUse to see how a player did against his prop line over time: for one market (hits, home runs, total bases, RBI, pitcher strikeouts or pitcher outs), one row per game with the closing line (the median across books, or one book's), the opening line (the same as the close wherever o
get_prop_movementUse to see how one player's prop line moved before a game: every capture we hold, book by book and oldest first, with the line, both prices and the minutes before the start. line_change is the last capture's line minus the first's. The number of captures varies by game and book.
get_market_oddsUse for the extra betting markets of a game as history: the first 5 innings winner, run line and total, and the 1st inning total and three-way result (the 1st inning total at 0.5 is the no-run-first-inning market). Pass game_id (from get_games or get_schedule) and market. For eac

You: "What is Gerrit Cole's whiff rate by pitch type this season?"
Claude: [calls get_pitch_mix]
You: "How often did Aaron Judge homer on a 3-2 count in 2025?" Claude: [calls get_plate_appearances]
You: "How often has Shohei Ohtani gone over his total bases line since 2023?" Claude: [calls get_prop_history]
Most clients connect to https://mcp.fastballapi.com/mcp directly. For a client that launches a local process instead:
git clone https://github.com/noahowsh/fastballapi-mcp.git && cd fastballapi-mcp && npm install
FASTBALLAPI_API_KEY=your_key node index.js
{ "mcpServers": { "fastballapi": { "command": "node", "args": ["/path/to/fastballapi-mcp/index.js"], "env": { "FASTBALLAPI_API_KEY": "your_key" } } } }
It forwards to the hosted server with your key, so every tool and credit cost is the same.
This repo also ships 16 free Claude skills in skills/ that turn Claude into a baseball analyst: pitch mix and whiff rate, run value, spray charts, Pythagorean record, game previews, odds analysis, prop modeling (pitcher strikeouts, hits, total bases), edge detection and backtesting. Each skill names the FastballAPI tools it calls and what they cost.
git clone https://github.com/noahowsh/fastballapi-mcp.git
Or install them as a Claude Code plugin:
/plugin marketplace add noahowsh/fastballapi-mcp
/plugin install fastballapi-skills@fastballapi
Or with the skills CLI: npx skills add noahowsh/fastballapi-mcp.
Point Claude at the skills/ folder, connect the MCP server below, and ask. The dispatch skill routes a request to the right two or three skills. Full list: skills/README.md.
The official Python client is on PyPI: fastballapi.
pip install fastballapi
export FASTBALLAPI_API_KEY=sk_live_...
from fastballapi import Client, to_dataframe
client = Client()
props = client.get_player_props( game_id="401815991", market="batter_home_runs", ) df = to_dataframe(props, key="props") print(df[["player_name", "bookmaker", "line", "over_odds", "under_odds"]].head(10))
