The Best MCP Servers for Browser Automation (2026)
By Steven Van ·
Browser Use compares 11 browser MCP servers on browser type, install, license and cost, with a 100-task eval of four tools.
Browser Use has published a comparison of 11 MCP servers for browser automation, covering Browser Use, Playwright MCP, Chrome DevTools MCP, Browserbase and Kernel, among others. For each server, the guide lists which browser it controls, how to install it, its license and its cost.
Which server for which job
- Playwright MCP: tests in an isolated browser, on Chrome, Firefox or WebKit. It is Microsoft's official server, licensed Apache-2.0 and free.
- Chrome DevTools MCP: performance, network and console debugging, including performance traces. Apache-2.0, free.
- Browser Harness: coding agents that need your own logged-in Chrome. MIT license, free. Its CLI can also drive Browser Use cloud browsers at $0.02 per browser-hour.
- Browser Use Cloud MCP: whole web tasks run on cloud browsers, many in parallel, with one tool call running a full browser agent.
- Vendor servers: Browserbase for natural-language actions, Kernel for Playwright code against cloud browsers, Steel for handing the browser to a human for logins, and Hyperbrowser for scrape, crawl and extract in one call.
How the guide frames the choice
The main difference between servers is which browser they drive: their own, your Chrome, or a cloud browser. The guide adds three more questions. Does the server expose low-level tools or run a whole agent? How much context does each page snapshot cost? What are the license and cost? Local servers are free and open source, while cloud servers bill for browser time.
It also notes that Playwright's README says coding agents may benefit from a CLI with skills instead of MCP, because CLI calls are more token-efficient. Several of the tools ship both.
The matched eval
Browser Use ran four tools on 100 public tasks from BU Bench V2.1. All used the same agent (Codex CLI with GPT-6 Luna), the same Browser Use cloud browser and the same judge. Browser Harness ran as a CLI and skill, not as its MCP server.
- Browser Harness: score 60.4, 2.1M median input tokens, $0.042 per task, 9.0 minutes.
- Playwright MCP: score 60.0, 4.4M tokens, $0.066, 8.3 minutes.
- Chrome DevTools MCP: score 61.0, 6.7M tokens, $0.097, 8.7 minutes.
- agent-browser: score 56.3, 3.3M tokens, $0.056, 11.3 minutes.
No tool won on score, since every paired interval against Browser Harness includes zero. Browser Harness used the fewest input tokens and cost the least per task, and Playwright MCP was fastest. The post lists its limits: one run per task, 100 of the benchmark's 200 tasks, one agent and model, and a fresh cloud browser for every task rather than a logged-in Chrome.
