Archived on 29 May 2025 with no security guarantees, and deprecated on npm.\n\n**Steel.** The hosted API has a public OpenAPI document, per-unit prices, $30 of starting credit and x402 payment for scrape, screenshot and PDF calls. The status page records three API or session-creation incidents of more than an hour in 90 days, and the documented CDP connection puts the API key in the URL.\n\n## Before you call either\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### Steel\n\n1. Use `POST /v1/scrape` for pages you only need to read. It starts no session and costs $5 per 1,000 calls, or $0.01 a call by x402\n2. Release every session with `POST /v1/sessions/{id}/release` and set `inactivityTimeout`. Browser time bills by the minute, rounded up\n3. Build the CDP URL as `wss://connect.steel.dev?apiKey=\u003ckey\u003e\u0026sessionId=\u003cid\u003e` and keep it out of logs, because it carries the key\n4. Launch sessions end after 15 minutes at most, and `timeout` cannot be changed on a live session\n5. CAPTCHA solving and Steel's managed proxies on Launch need $10 of paid balance. Free credit does not count\n\n## Questions\n\n### Which is better for AI agents, Puppeteer (archived MCP reference server) or Steel?\n\nSteel scores 70.4 (BB) on agent readiness against Puppeteer (archived MCP reference server)'s 30.6 (F), and leads in 6 of 7 scored categories. Puppeteer (archived MCP reference server) leads on transparency \u0026 trust.\n\n### Do Puppeteer (archived MCP reference server) and Steel need an API key?\n\nPuppeteer (archived MCP reference server) needs no key. Steel needs an API key. An agent can also pay Steel per call over x402, with no account.\n\n### Can an agent call Puppeteer (archived MCP reference server) and Steel without installing anything?\n\nPuppeteer (archived MCP reference server) runs on your own machine, with no hosted endpoint listed. Steel has a hosted endpoint at https://api.steel.dev.\n\n### Are Puppeteer (archived MCP reference server) and Steel open source?\n\nYes. Puppeteer (archived MCP reference server) is open source (MIT). Steel is open source (Proprietary cloud service under Steel's terms. steel-browser and the Node and Python SDKs are Apache-2.0. The MCP server and the CLI are MIT).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/puppeteer-reference-server-archived-vs-steel.json, and with the fewest tokens: https://www.anchorterminal.com/compare/puppeteer-reference-server-archived-vs-steel.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"puppeteer-reference-server-archived\", \"b\": \"steel\"}`.
