No service agreement is published, only a website terms of use, and the documented CDP connection puts the API key in the URL. **Puppeteer (archived MCP reference server).** Seven tools in about 700 tokens, every input with a `required` list. Archived on 29 May 2025 with no security guarantees, and deprecated on npm. ## Before you call either ### Anchor Browser 1. Send the key in the `anchor-api-key` header. For CDP, build `wss://connect.anchorbrowser.io?apiKey=&sessionId=` 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 ### Puppeteer (archived MCP reference server) 1. Don't install it for new work. playwright-mcp covers the same tasks with snapshots and annotations 2. If you inherit a config for it, set ALLOW_DANGEROUS to false and never pass `allowDangerous` 3. Never run it with a logged-in profile or on a host with internal services the browser can reach ## Questions ### Which is better for AI agents, Anchor Browser or Puppeteer (archived MCP reference server)?
