It has no MCP server of its own, Selenium Manager sends usage statistics by default, and Grid accepts unauthenticated sessions unless a username and password are set.\n\n**Skyvern.** The hosted MCP server annotates every tool as read-only or destructive and can advertise a 29 or 32-tool subset in place of 114, and the API has a written six-month deprecation policy. Every key and OAuth token carries full organisation authority, with no read-only or scoped credential, and no request rate limits are documented.\n\n## Before you call either\n\n### Selenium\n\n1. Install with `pip install selenium` (Python 3.10 or later) and let Selenium Manager fetch drivers. Do not set driver paths\n2. Use `WebDriverWait` with expected conditions, never fixed sleeps, and do not mix implicit and explicit waits\n3. Set `SE_AVOID_STATS=true` to stop Selenium Manager sending usage statistics\n4. Point coding agents at https://www.selenium.dev/llms.txt. Most Selenium 2 and 3 era examples use removed APIs\n5. Set `--username` and `--password` before exposing a Grid beyond localhost. Check `http://localhost:4444/status` before creating sessions\n\n### Skyvern\n\n1. Connect to https://api.skyvern.com/mcp/x/lean or /x/operate, or send `X-Skyvern-Scope`, so the client loads 32 or 29 tools. The scope filters the list and does not limit permissions\n2. Use a separate Skyvern organisation for each blast radius. Any key or OAuth token can read and write stored credentials and delete workflows\n3. Never pass passwords to `skyvern_act` or `skyvern_type`. Store them as credentials and call `skyvern_login`\n4. Set `max_steps` on tasks, or `x-max-steps-override` on agent runs, to cap credits. A run that reaches the cap ends as `timed_out`\n5. On 503 from POST /v1/run/agents, wait `Retry-After` seconds. No run was created, so resubmitting is safe\n\n## Questions\n\n### Which is better for AI agents, Selenium or Skyvern?\n\nSelenium scores 73.6 (BB) on agent readiness against Skyvern's 63.1 (B), and leads in 5 of 7 scored categories. Skyvern leads on agent ergonomics and security \u0026 auth.\n\n### Can an agent call Selenium and Skyvern without installing anything?\n\nNo hosted endpoint is listed for Selenium. Skyvern has a hosted endpoint at https://api.skyvern.com/v1.\n\n### Are Selenium and Skyvern open source?\n\nYes. Selenium is open source (Apache-2.0). Skyvern is open source (AGPL-3.0 for the open-source server, SDKs and MCP server. Skyvern Cloud is a proprietary service under Skyvern's terms, and its anti-bot measures aren't in the repository).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/selenium-vs-skyvern.json, and with the fewest tokens: https://www.anchorterminal.com/compare/selenium-vs-skyvern.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"selenium\", \"b\": \"skyvern\"}`.
