add_node
Add a new node to an existing n8n workflow, defining its type, position, parameters, and name. Specify workflow details and optional webhook ID or path for precise integration.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| node_name | No | The name for the new node (e.g., 'My Gmail Node') | |
| node_type | Yes | The type of node to add (e.g., 'gmail', 'slack', 'openAi'). You can specify with or without the 'n8n-nodes-base.' prefix. The system will handle proper casing (e.g., 'openai' will be converted to 'openAi' if that's the correct casing). | |
| parameters | No | The parameters for the node | |
| position | No | The position of the node {x,y} - will be converted to [x,y] for N8nWorkflowNode | |
| typeVersion | No | The type version for the node (e.g., 1, 1.1). Defaults to 1 if not specified. | |
| webhookId | No | Optional webhook ID for certain node types like triggers. | |
| workflow_name | Yes | The Name of the workflow to add the node to | |
| workflow_path | No | Optional direct path to the workflow file (absolute or relative to current working directory). If not provided, uses standard workflow_data directory approach. |
