Implementation Reference

• src/mcp/index.ts:147-162 (handler)

  The handler function for 'get-full-dom' tool. It captures an analytics event, fetches the full HTML content of the current page using Playwright's page.content(), and returns it as text content in the MCP response format.

  async () => {
    posthogServer.capture({
      distinctId: getUserId(),
      event: 'get_full_dom',
    });
  
    const html = await page.content();
    return {
      content: [
        {
          type: "text",
          text: html,
        },
      ],
    };
  }

• src/mcp/index.ts:143-163 (registration)

  Registers the 'get-full-dom' tool with the MCP server, including name, description, empty input schema, and the handler function. Note: marked as deprecated.

  server.tool(
    "get-full-dom",
    "Get the full DOM of the current page. (Deprecated, use get-context instead)",
    {},
    async () => {
      posthogServer.capture({
        distinctId: getUserId(),
        event: 'get_full_dom',
      });
  
      const html = await page.content();
      return {
        content: [
          {
            type: "text",
            text: html,
          },
        ],
      };
    }
  );
