@pipeworx/mlb-stats

MLB Stats API MCP — official MLB statistics: teams, standings, daily schedule and scores, rosters, player bios, season stats, per-game logs, batter-vs-pitcher splits, probable pitchers with posted lineups, and full box scores. No auth.

Part of Pipeworx — an MCP gateway connecting AI agents to 1882+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Tools

  • mlb_teams() — every MLB team with id, abbreviation, league, division, venue
  • mlb_standings(season?, league_id?) — division standings; defaults to the current season
  • mlb_schedule(date?) — games, scores, status and venue for a date (default today), with gamePk
  • mlb_roster(team_id) — active roster
  • mlb_player(person_id) — biographical profile
  • mlb_player_stats(player, season?, group?) — season hitting and/or pitching totals; player is a name or id
  • mlb_player_game_log(player, season?, group?, last?) — per-game lines, newest first (default last 15); pitchers default to the pitching log
  • mlb_matchup(batter, pitcher, season?) — batter-vs-pitcher history split by season
  • mlb_probable_pitchers(date?, team?) — probable starters and, once posted, the batting order for each game
  • mlb_boxscore(game_pk) — every batter's and pitcher's line plus team totals for one game

Player and team arguments accept names ("Yordan Alvarez", "Astros", "HOU") or numeric ids.

Data source

https://statsapi.mlb.com/api/v1/ — public, used by MLB.com itself. Lineups appear 2-4 hours before first pitch; probable pitchers as soon as MLB names them.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

config.json
{
  "mcpServers": {
    "mlb-stats": {
      "url": "https://gateway.pipeworx.io/mlb-stats/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/mlb-stats/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

config.json
{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Both URLs reach the same gateway and the same 1882+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

No MCP client? Call it over HTTP

Terminal
curl -X POST https://gateway.pipeworx.io/v1/tools/mlb_teams \
  -H 'Content-Type: application/json' \
  -d '{}'

No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/mlb_teams. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.

Standalone (no gateway account)

This package also runs as a local stdio MCP server — no Pipeworx account, no gateway round-trip:

config.json
{
  "mcpServers": {
    "mlb-stats": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-mlb-stats"]
    }
  }
}

Or run it directly to confirm it starts:

Terminal
npx -y @pipeworx/mcp-mlb-stats

It speaks MCP over stdin/stdout and answers initialize/tools/list/tools/call for only this pack's tools — none of the shared meta-tools the gateway connection above adds. Same source, same tools, no ask_pipeworx routing.

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:

Code
ask_pipeworx({ question: "your question about Mlb Stats data" })

The gateway picks the right tool and fills the arguments automatically.
