Which one, for what

Anchor Browser B

Good for Agents that must work inside signed-in accounts, with managed identities, MFA handling and a human sign-in link, and agents that need to start with no human signup.

Ahead on

  • Reliability, 80 against 57
  • Schema & documentation, 80 against 70

Also in its favour

  • A hosted endpoint, with nothing to install
  • Free to start without a card

Watch for

No service agreement or API terms found. anchorbrowser.io/terms is a website terms of use dated 16 March 2025

Playwright MCP B

Good 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 73
  • Maintenance & community, 84 against 57
  • Transparency & trust, 72 against 51

Also in its favour

  • No key needed to call it
  • Runs on your own machine

Verdicts

Anchor Browser

The API has a public OpenAPI 3.1 document, per-unit prices and Agent Access, an unauthenticated flow that issues a trial API key without a dashboard account. No service agreement is published, only a website terms of use, and the documented CDP connection puts the API key in the URL.

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.

Before you call either

Anchor Browser

  1. Send the key in the anchor-api-key header. For CDP, build wss://connect.anchorbrowser.io?apiKey=<key>&sessionId=<id> and keep that URL out of logs
  2. Set session.timeout.idle_timeout and max_duration and end sessions with DELETE. The default maximum is 180 minutes, and browser time bills by the minute
  3. Session creation is capped at 5 a minute on Free, 25 on Starter and 100 on Growth. On 429, wait for the Retry-After seconds
  4. Connect the Anchor MCP server or Anchor (all), not both, because the docs say the pair duplicates tool names
  5. Authenticated browsers, CAPTCHA solving and proxies by country need the Starter plan or higher. The Free plan and Agent Access keys run plain sessions and web tasks

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
