Which one, for what

Playwright MCP B

Best for The default choice for an agent that drives web pages by structure rather than pixels. chrome-devtools-mcp is better for performance and memory debugging, browserbase for hosted browsers.

Ahead on

  • Agent ergonomics, 84 against 67
  • Security & auth, 57 against 52

Also in its favour

  • Runs on your own machine

Watch for

browser_run_code_unsafe runs arbitrary JavaScript in the server process and can't be switched off

Puppeteer BB

Best for Agents that write and run Node.js scripts against Chrome or Firefox.

Ahead on

  • Reliability, 80 against 57
  • Schema & documentation, 81 against 70
  • Maintenance & community, 89 against 84

Also in its favour

  • Agent-ready, a grade of BB or better

Watch for

No MCP server, CLI or llms.txt of its own. The docs point agents to the separate chrome-devtools-mcp project

Verdicts

Playwright MCP

Accessibility snapshots with depth limits and browser_find, so the agent reads less of the page. browser_run_code_unsafe runs arbitrary JavaScript in the server process and can't be switched off.

Puppeteer

Puppeteer is a stable, Apache-2.0 library on 25.13.0, with ten releases since 27 July 2026, typed APIs, locators that wait and retry, and accessibility snapshots an agent can read. It has no MCP server or llms.txt of its own, and 10 of the 20 most recent CI runs on main failed between 7 and 13 October 2026.

Before you call either

Playwright MCP

  1. Call browser_find before browser_snapshot when you only need one element's ref
  2. Pass depth or a target to browser_snapshot on large pages
  3. Run with --isolated for untrusted sites. The default profile persists cookies between runs
  4. Add --caps only for the groups the task needs. Each group adds tools to the schema
  5. Pin a version in npx @playwright/mcp@<version>. 0.0.x releases can rename tools

Puppeteer

  1. Install with npm i puppeteer, which downloads a matching Chrome for Testing. Use puppeteer-core to bring your own browser
  2. Prefer page.locator() over page.$(). Locators wait for the element to be visible and stable before acting
  3. Read pages with page.accessibility.snapshot({interestingOnly: true}) rather than full HTML to keep output short
  4. Catch TimeoutError separately from TargetCloseError. The first can be retried, the second needs a new page or browser
  5. Packages are ESM only since 25.0.0. Use import puppeteer from 'puppeteer' rather than require
