get_player_stats

Instructions

Implementation Reference

• src/chess_mcp/server.py:98-110 (handler)

  The actual tool handler for 'get_player_stats'. Uses @mcp.tool decorator to register as an MCP tool, takes a username parameter, and calls the Chess.com API via make_api_request at endpoint 'player/{username}/stats'.

  @mcp.tool(description="Get a player's stats from Chess.com")
  async def get_player_stats(username: str) -> Dict[str, Any]:
      """
      Get a player's chess statistics from Chess.com.
  
      Args:
          username: The Chess.com username
  
      Returns:
          Player statistics data
      """
      logger.info("Fetching player stats", username=username)
      return await make_api_request(f"player/{username}/stats")

• src/chess_mcp/server.py:98-98 (registration)

  Registered via the @mcp.tool descriptor on line 98, which exposes it as a tool named 'get_player_stats' in the MCP server.

  @mcp.tool(description="Get a player's stats from Chess.com")

• src/chess_mcp/server.py:26-73 (helper)

  The make_api_request helper function that get_player_stats calls internally to make HTTP requests to the Chess.com API.

  Input schema: 'username' (str). The return type is Dict[str, Any]. This is implicitly defined by the function signature and the @mcp.tool decorator handles validation.
