Implementation Reference

• index.ts:262-281 (handler)

  Implementation of the browsercat_select tool handler. Waits for the selector, selects the option by value using Puppeteer, and returns success or error message.

  case "browsercat_select":
    try {
      await page.waitForSelector(args.selector);
      await page.select(args.selector, args.value);
      return {
        content: [{
          type: "text",
          text: `Selected ${args.selector} with: ${args.value}`,
        }],
        isError: false,
      };
    } catch (error) {
      return {
        content: [{
          type: "text",
          text: `Failed to select ${args.selector}: ${(error as Error).message}`,
        }],
        isError: true,
      };
    }

• index.ts:77-88 (registration)
