          "-4: an open exfiltration path that will never be fixed. The model can set `allowDangerous: true` on `puppeteer_navigate` to relaunch Chrome with the sandbox off, `puppeteer_evaluate` runs any script, and the README warns the browser can read local files and internal addresses. The package still drew 25,072 npm downloads in the week of 14 to 20 August 2026, the latest week the npm API returned to us. Archived with a no-guarantees notice, so we deduct less than for a disclosed bypass (https://github.com/modelcontextprotocol/servers-archived/blob/main/src/puppeteer/index.ts; https://api.npmjs.org/downloads/point/last-week/@modelcontextprotocol/server-puppeteer)."

No service agreement is published, only a website terms of use, and the documented CDP connection puts the API key in the URL.\n\n**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.\n\n## Before you call either\n\n### Anchor Browser\n\n1. Send the key in the `anchor-api-key` header. For CDP, build `wss://connect.anchorbrowser.io?apiKey=\u003ckey\u003e\u0026sessionId=\u003cid\u003e` and keep that URL out of logs\n2. 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\n3. 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\n4. Connect the `Anchor` MCP server or `Anchor (all)`, not both, because the docs say the pair duplicates tool names\n5. 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\n\n### Puppeteer (archived MCP reference server)\n\n1. Don't install it for new work. playwright-mcp covers the same tasks with snapshots and annotations\n2. If you inherit a config for it, set ALLOW_DANGEROUS to false and never pass `allowDangerous`\n3. Never run it with a logged-in profile or on a host with internal services the browser can reach\n\n## Questions\n\n### Which is better for AI agents, Anchor Browser or Puppeteer (archived MCP reference server)?\n\nAnchor Browser scores 67.3 (B) on agent readiness against Puppeteer (archived MCP reference server)'s 30.6 (F), and leads in 5 of 7 scored categories.
