Implementation Reference
- src/tools/browser.js:217-233 (handler)The `screenshot` method that executes the `browser_screenshot` tool logic using Puppeteer's `page.screenshot()` to capture the page screenshot and save it to a file.
async screenshot(savePath, fullPage = false, sessionId = 'default') { try { const page = this.pages.get(sessionId); if (!page) { return { success: false, error: '浏览器未启动' }; } const timestamp = new Date().toISOString().replace(/[:.]/g, '-'); const defaultPath = `screenshot-browser-${timestamp}.png`; const path = savePath || defaultPath; await page.screenshot({ path, fullPage }); return { success: true, path, fullPage, message: '截图已保存' }; } catch (error) { return { success: false, error: error.message }; } - src/tools/browser.js:75-86 (schema)The tool definition including the input schema for `browser_screenshot` in `getToolDefinitions()`.
{ name: 'browser_screenshot', description: '截取网页截图', inputSchema: { type: 'object', properties: { path: { type: 'string', description: '保存路径（可选）' }, fullPage: { type: 'boolean', description: '是否整页截图（可选）' }, sessionId: { type: 'string', description: '会话 ID（可选）' }, }, }, }, - src/tools/browser.js:135-136 (registration)The switch case in `executeTool` method that registers and dispatches the `browser_screenshot` tool call to its handler.
