Implementation Reference

• src/tools/workflow-tools.ts:312-334 (handler)

  The handler function that implements the n8n_delete_workflow tool. It extracts the workflow ID from arguments, validates it, calls the N8nApiClient's deleteWorkflow method, and returns a success response.

  n8n_delete_workflow: async (
    client: N8nApiClient,
    args: Record<string, unknown>
  ): Promise<ToolResult> => {
    const id = args.id as string;
    if (!id) {
      throw new Error('Workflow ID is required');
    }
  
    await client.deleteWorkflow(id);
  
    return {
      content: [
        {
          type: 'text' as const,
          text: JSON.stringify({
            success: true,
            message: `Workflow ${id} deleted successfully`,
          }, null, 2),
        },
      ],
    };
  },

• src/tools/workflow-tools.ts:117-130 (schema)

  The tool definition including name, description, and input schema for validating the 'id' parameter.

  {
    name: 'n8n_delete_workflow',
    description: 'Permanently delete a workflow. This action cannot be undone.',
    inputSchema: {
      type: 'object',
      properties: {
        id: {
          type: 'string',
          description: 'The workflow ID to delete',
        },
      },
      required: ['id'],
    },
  },

• src/server.ts:122-125 (registration)

  The registration/dispatch logic in the MCP server that routes tool calls matching workflowToolHandlers (including n8n_delete_workflow) to the appropriate handler function.

  if (name in workflowToolHandlers) {
    const handler = workflowToolHandlers[name as keyof typeof workflowToolHandlers];
    return handler(client, args);
  }
