• server.py:416-444 (handler)

  The main handler function for the 'netbox_bulk_update_objects' tool. It is registered via the @mcp.tool() decorator. Validates the object_type using the NETBOX_OBJECT_TYPES mapping, resolves the API endpoint, and calls the NetBoxRestClient's bulk_update method to perform the bulk PATCH request.
  @mcp.tool() def netbox_bulk_update_objects(object_type: str, data: list): """ Update multiple objects in NetBox in a single request. Args: object_type: String representing the NetBox object type (e.g. "devices", "ip-addresses") data: List of dicts containing the object data to update (must include "id" field) Returns: List of updated objects Example: To update multiple devices: netbox_bulk_update_objects("devices", [ {"id": 1, "status": "offline"}, {"id": 2, "status": "maintenance"} ]) """ # Validate object_type exists in mapping if object_type not in NETBOX_OBJECT_TYPES: valid_types = "\n".join(f"- {t}" for t in sorted(NETBOX_OBJECT_TYPES.keys())) raise ValueError(f"Invalid object_type.

• server.py:5-98 (helper)

  Shared helper constant mapping object_type names to NetBox API endpoints. Used by the tool's handler for validation and endpoint resolution.

• netbox_client.py:279-296 (helper)

  Core helper method in NetBoxRestClient that implements the bulk update by sending a PATCH request to the NetBox REST API bulk endpoint with the provided data list.
  def bulk_update(self, endpoint: str, data: List[Dict[str, Any]]) -> List[Dict[str, Any]]: """ Update multiple objects in NetBox via the REST API.

• server.py:418-434 (schema)

  The docstring of the handler function defines the tool's input schema (parameters: object_type str, data list[dict]), expected data format (data items must include 'id'), return type, and usage examples.
