Implementation Reference

src/index.ts:1099-1128 (handler)

MCP tool handler for 'deactivate-workflow': validates arguments, retrieves N8nClient instance, calls deactivateWorkflow method, and returns success/error response.

case "deactivate-workflow": {
  const { clientId, id } = args as { clientId: string; id: string };
  const client = clients.get(clientId);
  if (!client) {
    return {
      content: [{
        type: "text",
        text: "Client not initialized. Please run init-n8n first.",
      }],
      isError: true
    };
  }

  try {
    const workflow = await client.deactivateWorkflow(id);
    return {
      content: [{
        type: "text",
        text: `Successfully deactivated workflow:\n${JSON.stringify(workflow, null, 2)}`,
      }]
    };
  } catch (error) {
    return {
      content: [{
        type: "text",
        text: error instanceof Error ? error.message : "Unknown error occurred",
      }],
      isError: true
    };
  }

src/index.ts:495-506 (registration)

Tool registration in listTools handler: defines name, description, and input schema for 'deactivate-workflow'.

{
  name: "deactivate-workflow",
  description: "Deactivate a workflow by ID. This will prevent the workflow from running. IMPORTANT: Arguments must be provided as compact, single-line JSON without whitespace or newlines.",
  inputSchema: {
    type: "object",
    properties: {
      clientId: { type: "string" },
      id: { type: "string" }
    },
    required: ["clientId", "id"]
  }
},

src/index.ts:498-505 (schema)

Input schema definition for 'deactivate-workflow' tool: requires clientId and id as strings.

inputSchema: {
  type: "object",
  properties: {
    clientId: { type: "string" },
    id: { type: "string" }
  },
  required: ["clientId", "id"]
}

src/index.ts:198-202 (helper)

N8nClient helper method: makes POST request to n8n API endpoint /workflows/{id}/deactivate to deactivate the workflow.

async deactivateWorkflow(id: string): Promise<N8nWorkflow> {
  return this.makeRequest<N8nWorkflow>(`/workflows/${id}/deactivate`, {
    method: 'POST',
  });
}
