TOS MCP Server

Instructions

Implementation Reference

• src/tos_mcp_server/handlers.py:39-52 (handler)

  The handler function that implements the tos_list_buckets tool. It calls tos_client.list_buckets() to retrieve all buckets and formats them as a JSON list with name, creation_date, and location.

  async def list_buckets(_args: Dict[str, Any]) -> List[TextContent]:
      """列举存储桶"""
      try:
          resp = tos_client.list_buckets()
          buckets = []
          for bucket in resp.buckets:
              buckets.append({
                  "name": bucket.name,
                  "creation_date": str(bucket.creation_date) if bucket.creation_date else None,
                  "location": bucket.location
              })
          return [TextContent(type="text", text=json.dumps(buckets, indent=2, ensure_ascii=False))]
      except Exception as e:
          return [TextContent(type="text", text=f"列举存储桶失败: {str(e)}")]

• src/tos_mcp_server/server.py:53-60 (registration)

  Tool registration in list_tools() function, defining the name, description, and input schema (empty properties) for tos_list_buckets.

  Tool(
      name="tos_list_buckets",
      description="列举 TOS 存储桶",
      inputSchema={
          "type": "object",
          "properties": {}
      }
  ),

• src/tos_mcp_server/server.py:339-340 (registration)

  Dispatch logic in call_tool() that routes the tos_list_buckets tool call to the list_buckets handler function.

  elif name == "tos_list_buckets":
      return await list_buckets(arguments)

• src/tos_mcp_server/server.py:56-59 (schema)

  Input schema for the tos_list_buckets tool, which requires no parameters (empty properties).

  inputSchema={
      "type": "object",
      "properties": {}
  }
