Browser Run - Browser Rendering adds Chrome DevTools Protocol (CDP) and MCP client support

Browser Rendering now exposes the Chrome DevTools Protocol (CDP), the low-level protocol that powers browser automation. The growing ecosystem of CDP-based agent tools, along with existing CDP automation scripts, can now use Browser Rendering directly.

Any CDP-compatible client, including Puppeteer and Playwright, can connect from any environment, whether that is Cloudflare Workers, your local machine, or a cloud environment. All you need is your Cloudflare API key.

For any existing CDP script, switching to Browser Rendering is a one-line change:

const puppeteer = require("puppeteer-core");

const browser = await puppeteer.connect({
	browserWSEndpoint: `wss://api.cloudflare.com/client/v4/accounts/${ACCOUNT_ID}/browser-rendering/devtools/browser?keep_alive=600000`,
	headers: { Authorization: `Bearer ${API_TOKEN}` },
});

const page = await browser.newPage();
await page.goto("https://example.com");
console.log(await page.title());
await browser.close();

Additionally, MCP clients like Claude Desktop, Claude Code, Cursor, and OpenCode can now use Browser Rendering as their remote browser via the chrome-devtools-mcp ↗︎ package.

Here is an example of how to configure Browser Rendering for Claude Desktop:

{
	"mcpServers": {
		"browser-rendering": {
			"command": "npx",
			"args": [
				"-y",
				"chrome-devtools-mcp@latest",
				"--wsEndpoint=wss://api.cloudflare.com/client/v4/accounts/<ACCOUNT_ID>/browser-rendering/devtools/browser?keep_alive=600000",
				"--wsHeaders={\"Authorization\":\"Bearer <API_TOKEN>\"}"
			]
		}
	}
}
