Implementation Reference

• mcp_server_azure/azure_server.py:192-195 (handler)

  Executes the blob_container_list tool by listing all containers in the blob storage account using BlobServiceClient and extracting their names into a response dictionary.
  elif name == "blob_container_list": containers = blob_service_client.list_containers() container_names = [container.name for container in containers] response = {"container_names": container_names}
• mcp_server_azure/azure_tools.py:21-25 (schema)

  Defines the input schema for the blob_container_list tool, specifying no required input properties.
  Tool( name="blob_container_list", description="List all Blob Storage containers", inputSchema={"type": "object", "properties": {}}, ),
• mcp_server_azure/azure_server.py:171-176 (registration)

  Registers the blob_container_list tool (among others) by returning the list from get_azure_tools() in response to list_tools requests.
  @server.list_tools() async def list_tools() -> list[Tool]: """List available Azure tools""" logger.debug("Handling list_tools request") return get_azure_tools() # Use get_azure_tools
• mcp_server_azure/azure_server.py:177-238 (handler)

  The dispatch handler function for all blob storage tools, including the specific logic for blob_container_list.

• mcp_server_azure/azure_server.py:432-436 (handler)

  Dispatches blob_container_list (and other blob_ tools) to the specific blob storage handler from the main call_tool function.
