## Which one, for what

### Chrome DevTools MCP (BB)

Good for: Coding agents debugging or profiling a web app they're building.

Ahead on:
- Reliability, 83 against 58
- Schema & documentation, 87 against 74
- Agent ergonomics, 83 against 75
- Security & auth, 63 against 56
- Payments & pricing, 60 against 40
- Maintenance & community, 93 against 83
- Transparency & trust, 81 against 61

Also in its favour:
- Agent-ready, a grade of BB or better
- No key needed to call it
- Runs on your own machine
- Open source

Watch for: Usage statistics go to Google by default until you pass `--no-usage-statistics`

### Notte (B)

Good for: Teams that want hosted browsers together with agents, vaults for logins, personas with mailboxes and scheduled browser functions behind one key.

Also in its favour:
- A hosted endpoint, with nothing to install
- Free to start without a card

Watch for: status.notte.cc shows the Scrape API down on 15 of 90 days (about 6 hours in total) and CAPTCHA solving at 88.9 per cent availability

## 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
