## Which one, for what

### Anchor Browser (B)

Good for: Agents that must work inside signed-in accounts, with managed identities, MFA handling and a human sign-in link, and agents that need to start with no human signup.

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

Watch for: No service agreement or API terms found. anchorbrowser.io/terms is a website terms of use dated 16 March 2025

### Chrome DevTools MCP (BB)

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

Ahead on:
- Schema & documentation, 87 against 80
- Agent ergonomics, 83 against 73
- Security & auth, 63 against 54
- Maintenance & community, 93 against 57
- Transparency & trust, 81 against 51

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`

## Verdicts

**Anchor Browser.** The API has a public OpenAPI 3.1 document, per-unit prices and Agent Access, an unauthenticated flow that issues a trial API key without a dashboard account. No service agreement is published, only a website terms of use, and the documented CDP connection puts the API key in the URL.

**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`.

## Before you call either

### Anchor Browser

1. Send the key in the `anchor-api-key` header. For CDP, build `wss://connect.anchorbrowser.io?apiKey=<key>&sessionId=<id>` and keep that URL out of logs
2. Set `session.timeout.idle_timeout` and `max_duration` and end sessions with DELETE. The default maximum is 180 minutes, and browser time bills by the minute
3. Session creation is capped at 5 a minute on Free, 25 on Starter and 100 on Growth. On 429, wait for the `Retry-After` seconds
4. Connect the `Anchor` MCP server or `Anchor (all)`, not both, because the docs say the pair duplicates tool names
5. Authenticated browsers, CAPTCHA solving and proxies by country need the Starter plan or higher. The Free plan and Agent Access keys run plain sessions and web tasks

### 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
