Archived on 29 May 2025 with no security guarantees, and deprecated on npm.\n\n## Before you call either\n\n### agent-browser\n\n1. Run `agent-browser install` once after `npm install -g agent-browser`. It downloads Chrome for Testing\n2. Take a fresh `snapshot -i` after any navigation. Refs survive same-document changes only\n3. Pass `--json` for machine-readable results and `--max-output` to cap page text\n4. Set `--allowed-domains`, `--action-policy` and `--content-boundaries` for untrusted sites. None is on by default, and the allowlist rejects `--profile`, `--cdp` and `--restore`\n5. Start MCP with `agent-browser mcp`, and add profiles such as `--tools core,network` only when needed\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, agent-browser or Puppeteer (archived MCP reference server)?\n\nagent-browser scores 66.6 (B) on agent readiness against Puppeteer (archived MCP reference server)'s 30.6 (F), and leads in 5 of 7 scored categories.
