Implementation Reference
- src/browserSession.ts:469-476 (handler)The core handler implementation for the 'click' tool. It uses doAction wrapper and handleMouseInteraction helper to perform the mouse click at the given coordinate via Puppeteer page.mouse.click.*/ async click(coordinate: string): Promise<BrowserActionResult> { return this.doAction(async (page) => { await this.handleMouseInteraction(page, coordinate, async (x, y) => { await page.mouse.click(x, y); }); }); }
- src/index.ts:83-95 (schema)The input schema for the 'click' tool, defining the required 'coordinate' parameter as a string in 'x,y' format.name: "click", description: "在指定坐标位置点击", inputSchema: { type: "object", properties: { coordinate: { type: "string", description: "点击位置的坐标，格式为 'x,y'", }, }, required: ["coordinate"], }, },
- src/index.ts:189-194 (registration)The dispatching logic in the MCP tool call handler that validates the input and calls the browserSession.click method.case "click": if (!args?.coordinate) { throw new Error("coordinate参数是必需的"); } result = await this.browserSession.click(args.coordinate as string); break;
- src/browserSession.ts:421-465 (helper)Helper method used by 'click' (and hover) to handle mouse interactions, including network activity monitoring and post-click navigation waiting.private async handleMouseInteraction( page: Page, coordinate: string, action: (x: number, y: number) => Promise<void>, ): Promise<void> { const [x, y] = coordinate.split(",").map(Number); // 设置网络请求监控 let hasNetworkActivity = false; const requestListener = () => { hasNetworkActivity = true; }; page.on("request", requestListener); // 执行鼠标操作 await action(x, y); this.currentMousePosition = coordinate; // 小延迟检查操作是否触发了任何网络活动 await delay(100); if (hasNetworkActivity) { // 如果检测到网络活动，等待导航/加载 await page .waitForNavigation({ waitUntil: ["domcontentloaded", "networkidle2"], timeout: 15000, }) .catch(async () => { // 如果networkidle2失败，尝试仅等待domcontentloaded console.log("鼠标交互后网络静默等待失败，尝试仅等待DOM"); await page.waitForNavigation({ waitUntil: ["domcontentloaded"], timeout: 15000, }).catch(() => { // 如果还是失败，就忽略，继续执行 console.log("鼠标交互后导航等待失败，继续执行"); }); }); await this.waitTillHTMLStable(page); } // 清理监听器 page.off("request", requestListener); }
- src/index.ts:309-310 (registration)Success message generation for the 'click' tool in the response builder.case "click": return `✅ 点击操作完成${result.currentMousePosition ? ` (位置: ${result.currentMousePosition})` : ""}`;
