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.

Chrome DevTools MCP

Performance traces, network inspection, heap snapshots and Lighthouse audits in one server. Usage statistics go to Google by default until you pass --no-usage-statistics.

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

Chrome DevTools MCP

  1. Pass pageId on every page tool. Call list_pages first to get it
  2. Start with --slim for plain browsing, or turn off categories you don't need
  3. Run with --isolated for untrusted sites. The default profile persists between runs
  4. Use filePath on large outputs such as traces and snapshots to keep them out of context
  5. Add --no-usage-statistics if the operator hasn't agreed to Google telemetry
