Implementation Reference

• src/tools.ts:80-118 (registration)

  Registration/definition of the 'update_workflow' tool in the tools array, including its name, description, and input schema (workflowId required, with optional name, nodes, connections, active, settings, tags).

  {
    name: "update_workflow",
    description: "Update an existing workflow",
    inputSchema: {
      type: "object",
      properties: {
        workflowId: {
          type: "string",
          description: "The ID of the workflow to update",
        },
        name: {
          type: "string",
          description: "New name for the workflow",
        },
        nodes: {
          type: "array",
          description: "Updated nodes array",
        },
        connections: {
          type: "object",
          description: "Updated connections object",
        },
        active: {
          type: "boolean",
          description: "Activation status",
        },
        settings: {
          type: "object",
          description: "Updated workflow settings",
        },
        tags: {
          type: "array",
          items: { type: "string" },
          description: "Updated tags",
        },
      },
      required: ["workflowId"],
    },
  },

• src/handlers.ts:25-33 (schema)

  Zod validation schema 'UpdateWorkflowSchema' for update_workflow: validates workflowId (string), name, nodes, connections, active, settings, and tags.

  const UpdateWorkflowSchema = z.object({
    workflowId: z.string(),
    name: z.string().optional(),
    nodes: z.array(z.any()).optional(),
    connections: z.record(z.any()).optional(),
    active: z.boolean().optional(),
    settings: z.record(z.any()).optional(),
    tags: z.array(z.string()).optional(),
  });

• src/handlers.ts:90-93 (handler)

  Handler case for 'update_workflow' in handleToolCall: parses args with UpdateWorkflowSchema, destructures workflowId from updateData, then calls client.updateWorkflow(workflowId, updateData).

  case "update_workflow": {
    const { workflowId, ...updateData } = UpdateWorkflowSchema.parse(args);
    return await client.updateWorkflow(workflowId, updateData);
  }

• src/n8n-client.ts:81-84 (helper)

  N8nClient.updateWorkflow method: sends a PATCH request to /api/v1/workflows/{id} with the workflow data, and validates the response with WorkflowSchema.

  async updateWorkflow(id: string, workflow: any) {
    const response = await this.client.patch(`/api/v1/workflows/${id}`, workflow);
    return WorkflowSchema.parse(response.data);
  }
