Implementation Reference

• src/jvlink_mcp_server/server.py:584-597 (handler)

  The MCP tool registration and handler function 'analyze_nar_jockey_stats' for the 'nar_jockey_stats' tool. It executes the tool logic by calling the underlying 'get_nar_jockey_stats' helper.

  @mcp.tool(name="nar_jockey_stats")
  def analyze_nar_jockey_stats(
      jockey_name: str,
      venue: Optional[str] = None,
      year_from: Optional[str] = None
  ) -> dict:
      """NAR地方競馬の騎手成績を分析
  
      地方競馬の騎手名を指定して、勝率・複勝率・騎乗数などを調べられます。
      """
      with DatabaseConnection() as db:
          return _get_nar_jockey_stats(
              db, jockey_name=jockey_name, venue=venue, year_from=year_from
          )

• src/jvlink_mcp_server/database/high_level_api.py:702-712 (helper)

  The database high-level helper function 'get_nar_jockey_stats' which implements the core logic for fetching NAR jockey statistics.

  def get_nar_jockey_stats(
      db_connection,
      jockey_name: str,
      venue: Optional[str] = None,
      year_from: Optional[str] = None
  ) -> Dict[str, Any]:
      """NAR地方競馬の騎手成績を取得（JRA版に委譲）"""
      return _jockey_stats_impl(
          db_connection, jockey_name=jockey_name, venue=venue,
          year_from=year_from, source='nar'
      )
