## 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

1. Use x402.browserbase.com when you have a wallet and no key. Terminate the session to get unused minutes refunded
2. Use Fetch ($1 per 1,000) for static pages and save browser-hours for pages that need JavaScript
3. Close sessions explicitly. Each session bills at least one minute, and idle ones keep billing
4. Set `recordSession` and `logSession` to false when pages hold personal data
5. On 429, wait `retry-after` seconds before creating another session

### 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
