Implementation Reference

• main.py:547-552 (handler)

  MCP tool handler function that registers and executes the tool by delegating to the Vultr provider.

  @mcp.tool()

      """
      获取Vultr实例带宽使用情况
      """
      return vultr_provider.get_instance_bandwidth(instance_id)

• providers/vultr_provider.py:335-372 (helper)

  Core helper method in VultrProvider class that performs the actual API request to Vultr for instance bandwidth data.
