Implementation Reference

• src/browser.ts:50-59 (handler)

  The core handler logic for the 'click' tool, implementing the click action using Puppeteer by waiting for the selector and calling page.click.

  async click(selector: string) {
      const page = await this.init();
      try {
          await page.waitForSelector(selector, { timeout: 5000 });
          await page.click(selector);
          return `Clicked element: ${selector}`;
      } catch (e: any) {
          throw new Error(`Failed to click ${selector}: ${e.message}`);
      }
  }

• src/index.ts:37-47 (schema)

  Input schema definition for the 'click' tool, specifying the required 'selector' parameter.

  {
      name: "click",
      description: "Click an element on the page identified by a CSS selector",
      inputSchema: {
          type: "object",
          properties: {
              selector: { type: "string", description: "CSS selector of the element to click" },
          },
          required: ["selector"],
      },
  },

• src/index.ts:123-125 (registration)

  Registration and dispatching logic in the MCP CallToolRequestSchema handler, invoking browserManager.click for the 'click' tool.

  case "click":
      result = await browserManager.click(String(args?.selector));
      break;
