Implementation Reference

• src/index.ts:544-560 (handler)

  Handler for the 'get_element_text' tool. Validates input with GetElementTextSchema, retrieves text content from the specified selector using Playwright's page.textContent method, and returns the text or '(empty)' if none.

  case 'get_element_text': {
    if (!currentPage) {
      throw new Error('No browser page available. Launch a browser first.');
    }
  
    const params = GetElementTextSchema.parse(args);
    const text = await currentPage.textContent(params.selector, { timeout: params.timeout });
  
    return {
      content: [
        {
          type: 'text',
          text: `Element text: ${text || '(empty)'}`
        }
      ]
    };
  }

• src/index.ts:44-47 (schema)

  Zod schema for validating input parameters of the get_element_text tool: selector (required string) and optional timeout (default 5000ms).

  const GetElementTextSchema = z.object({
    selector: z.string(),
    timeout: z.number().default(5000)
  });

• src/index.ts:237-255 (registration)

  Tool registration in the listTools response, defining name, description, and inputSchema matching the Zod schema.

  {
    name: 'get_element_text',
    description: 'Get text content of an element',
    inputSchema: {
      type: 'object',
      properties: {
        selector: {
          type: 'string',
          description: 'CSS selector for the element'
        },
        timeout: {
          type: 'number',
          default: 5000,
          description: 'Timeout in milliseconds'
        }
      },
      required: ['selector']
    }
  },
