Implementation Reference

• src/index.ts:1361-1391 (handler)

  Handler function that executes the delete-user tool by retrieving the N8nClient instance and invoking its deleteUser method with the provided idOrEmail.

  case "delete-user": {
    const { clientId, idOrEmail } = args as { clientId: string; idOrEmail: string };
    const client = clients.get(clientId);
    if (!client) {
      return {
        content: [{
          type: "text",
          text: "Client not initialized. Please run init-n8n first.",
        }],
        isError: true
      };
    }
  
    try {
      await client.deleteUser(idOrEmail);
      return {
        content: [{
          type: "text",
          text: `Successfully deleted user: ${idOrEmail}`,
        }]
      };
    } catch (error) {
      return {
        content: [{
          type: "text",
          text: error instanceof Error ? error.message : "Unknown error occurred",
        }],
        isError: true
      };
    }
  }

• src/index.ts:603-614 (registration)

      type: "object",
      properties: {
        clientId: { type: "string" },
        idOrEmail: { type: "string" }
