Each session bills at least one minute, and idle ones keep billing\n4. Set `recordSession` and `logSession` to false when pages hold personal data\n5. On 429, wait `retry-after` seconds before creating another session\n\n### Chrome DevTools MCP\n\n1. Pass `pageId` on every page tool. Call `list_pages` first to get it\n2. Start with `--slim` for plain browsing, or turn off categories you don't need\n3. Run with `--isolated` for untrusted sites. The default profile persists between runs\n4.
