Implementation Reference

• src/n8n-client.ts:120-128 (handler)

  The deleteWorkflow function makes a DELETE request to the n8n API to delete a workflow by ID. It constructs the API URL, sends the request with proper headers, and returns a confirmation object with deleted: true and the workflowId.

  export async function deleteWorkflow(workflowId: string) {
    const { baseUrl } = getEnv();
    const response = await fetch(`${baseUrl}/api/v1/workflows/${workflowId}`, {
      method: 'DELETE',
      headers: buildHeaders(),
    });
    if (!response.ok) throw new Error(`n8n API returned ${response.status}`);
    return { deleted: true, workflowId };
  }

• src/index.ts:68-75 (registration)

  Tool registration for 'delete_workflow' with description 'Delete an n8n workflow by ID.' and input schema defining a required workflowId string property.

    name: 'delete_workflow',
    description: 'Delete an n8n workflow by ID.',
    inputSchema: {
      type: 'object',
      properties: { workflowId: { type: 'string' } },
      required: ['workflowId'],
    },
  },

• src/index.ts:234-238 (handler)

  Handler for 'delete_workflow' tool calls - validates the workflowId argument using Zod schema, calls the deleteWorkflow function, and returns the result as JSON text content.

  if (name === 'delete_workflow') {
    const { workflowId } = z.object({ workflowId: z.string() }).parse(args);
    const deleted = await deleteWorkflow(workflowId);
    return { content: [{ type: 'text', text: JSON.stringify(deleted, null, 2) }] };
  }
