Implementation Reference

• src/index.ts:161-179 (handler)

  Handler for the 'stop_instance' tool. Parses input arguments using StopInstanceSchema, retrieves the Scrapybara instance by ID, stops it, and returns the response as JSON.

  case "stop_instance": {
    const args = StopInstanceSchema.parse(request.params.arguments);
    const instance = await client.get(args.instance_id, {
      abortSignal: currentController.signal,
    });
  
    const response = await instance.stop({
      abortSignal: currentController.signal,
    });
  
    return {
      content: [
        {
          type: "text",
          text: JSON.stringify(response, null, 2),
        } as TextContent,
      ],
    };
  }

• src/schemas.ts:14-16 (schema)

  Zod schema defining the input for stop_instance tool: requires 'instance_id' as a string.

  export const StopInstanceSchema = z.object({
    instance_id: z.string().describe("The ID of the instance to stop."),
  });

• src/index.ts:83-87 (registration)

  Registration of the 'stop_instance' tool in the ListTools response, including name, description, and input schema.

    name: "stop_instance",
    description: "Stop a running Scrapybara instance.",
