Usage statistics go to Google by default until you pass `--no-usage-statistics`.\n\n**Notte.** Notte publishes an OpenAPI 3.1 contract for 100 operations, a hosted MCP server with eight tools and OAuth, and a free plan with $10 of credits and no card. Its status page records about six hours of Scrape API downtime in 90 days, and a bot check blocked our read of the terms and privacy policy.\n\n## Before you call either\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. Use `filePath` on large outputs such as traces and snapshots to keep them out of context\n5. Add `--no-usage-statistics` if the operator hasn't agreed to Google telemetry\n\n### Notte\n\n1. Send `Authorization: Bearer $NOTTE_API_KEY` to https://api.notte.cc. A person creates the key in the console at console.notte.cc first\n2. Stop every session when the task ends. Sessions close after 3 idle minutes or 15 minutes in total by default, and the Free plan caps a session at 15 minutes\n3. Use https://api.notte.cc/mcp for browser work. Function and agent administration tools are only on https://api.notte.cc/mcp/full\n4. Back off on 429 and on 529, which means the cluster has too many sessions. The SDKs do not retry rate limits for you\n5. Download session replays within 24 hours. The recordings page says they are deleted after that\n\n## Questions\n\n### Which is better for AI agents, Chrome DevTools MCP or Notte?\n\nChrome DevTools MCP scores 77 (BB) on agent readiness against Notte's 63.2 (B), and leads in every scored category.\n\n### Do Chrome DevTools MCP and Notte need an API key?\n\nChrome DevTools MCP needs no key.
