Verdicts

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.

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.

Before you call either

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

Notte

  1. Send Authorization: Bearer $NOTTE_API_KEY to https://api.notte.cc. A person creates the key in the console at console.notte.cc first
  2. 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
  3. Use https://api.notte.cc/mcp for browser work. Function and agent administration tools are only on https://api.notte.cc/mcp/full
  4. Back off on 429 and on 529, which means the cluster has too many sessions. The SDKs do not retry rate limits for you
  5. Download session replays within 24 hours. The recordings page says they are deleted after that

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
