• amap_mcp_server/server.py:634-665 (handler)

  The maps_distance tool handler function, registered via @mcp.tool() decorator. It measures distance between origins and destination coordinates using Amap's distance API, supporting types like driving (1), walking (2), or straight-line (0). Returns results with distance and duration.

  @mcp.tool()
