Verdicts
Browserbase
x402 sessions at x402.browserbase.com with no account, $0.12 an hour, unused minutes refunded. The hosted MCP setup page passes the API key as ?browserbaseApiKey= 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
Browserbase
- Use x402.browserbase.com when you have a wallet and no key. Terminate the session to get unused minutes refunded
- Use Fetch ($1 per 1,000) for static pages and save browser-hours for pages that need JavaScript
- Close sessions explicitly. Each session bills at least one minute, and idle ones keep billing
- Set
recordSessionandlogSessionto false when pages hold personal data - On 429, wait
retry-afterseconds before creating another session
Playwright MCP
- Call
browser_findbeforebrowser_snapshotwhen you only need one element's ref - Pass
depthor atargettobrowser_snapshoton large pages - Run with
--isolatedfor untrusted sites. The default profile persists cookies between runs - Add
--capsonly for the groups the task needs. Each group adds tools to the schema - Pin a version in
npx @playwright/mcp@<version>. 0.0.x releases can rename tools
