Uses FastAPI as the web framework for building the API, providing automatic API documentation generation, schema validation, and type safety for the MLB data endpoints.
Repository is hosted on GitHub, allowing for version control, collaboration, and distribution of the MCP server code.
Provides comprehensive access to MLB statistics and baseball data, including team standings, game schedules, player statistics, team information, live game data, game highlights, player and team search, draft information, and advanced sabermetrics.
Built with Python 3.10+, utilizing Python's capabilities for data processing and API integration with the MLB Stats API.
MLB API MCP Server
A Model Context Protocol (MCP) server that provides comprehensive access to MLB statistics and baseball data through a FastMCP-based interface.
Overview
This MCP server acts as a bridge between AI applications and MLB data sources, enabling seamless integration of baseball statistics, game information, player data, and more into AI workflows and applications.
Features
MLB Data Access
- Current standings for all MLB teams with flexible filtering by league, season, and date
- Game schedules and results with date range support
- Player statistics including traditional and sabermetric stats (WAR, wOBA, wRC+)
- Team information and rosters with various roster types
- Live game data including boxscores, linescores, and play-by-play
- Game highlights and scoring plays
- Player and team search functionality
- Draft information and award recipients
- Game pace statistics and lineup information
MCP Tools
All MLB/statistics/game/player/team/etc. functionality is exposed as MCP tools, not as RESTful HTTP endpoints. These tools are accessible via the /mcp/
endpoint using the MCP protocol. For a list of available tools and their descriptions, visit /tools/
when the server is running.

/docs
- Interactive API documentation and tool listing/health/
- Health check endpoint/mcp/info
- MCP server information/tools/
- List of all available MCP tools/mcp/
(POST) - MCP protocol endpoint for MCP-compatible clients
Note: There are no RESTful HTTP endpoints for MLB/statistics/game/player/team/etc. All such functionality is accessed via MCP tools through the
/mcp/
endpoint.
