The API token travels in the URL query string by default, cloud tokens carry no scopes, and no machine payment route exists.\n\n**Functionize MCP server.** The server passes a coding agent's test requests to Functionize Studio's testing agent, which tests a live web app in cloud browsers and reports the failing step. It uses OAuth with read and write scopes and has a no-card free plan. Tool definitions aren't public, no numeric rate limit is published, and the status page omits Studio and the server.\n\n## Before you call either\n\n### Browserless\n\n1. Send the token as `Authorization: Bearer` to the MCP server. On REST and WebSocket routes it goes in `?token=`, so keep those URLs out of logs\n2. Close sessions as soon as the work is done. Browser time bills one unit per 30 seconds, rounded up, idle or not\n3. For multi-step work with `browserless_agent`, set `keepSessionAlive: true` on the first call and pass the returned `sessionId` after that. Sessions are one-shot by default since server 1.33.0\n4. On 429, back off and retry. It means the plan's concurrency limit or queue is full, usually from sessions left open\n5. Match the path to the protocol. Use `/chromium` for CDP clients and `/chromium/playwright` only for `playwright.connect()`\n\n### Functionize MCP server\n\n1. Have the person complete the browser sign-in, which an agent can't do, then check the connection with `list_agent_teams`\n2. Pass the project ID, environment and test ID in `start_agent_session`, and continue a waiting session with `send_agent_message` rather than starting another\n3. Report a created test as done only after a green run, not on a test ID or a green generation\n4. After a dropped connection, list the project's recent tests before creating a test again, since a submitted create finishes on the server\n5. Send the `X-Functionize-Team-Id` header to pin a team, and keep credentials in masked Studio variables, never in prompts\n\n## Questions\n\n### Which is better for AI agents, Browserless or Functionize MCP server?\n\nBrowserless scores 70.4 (BB) on agent readiness against Functionize MCP server's 44.7 (E), and leads in 6 of 7 scored categories.\n\n### Do Browserless and Functionize MCP server need an API key?\n\nBrowserless takes an API key or an OAuth sign-in. Functionize MCP server uses an OAuth sign-in.\n\n### Can an agent call Browserless and Functionize MCP server without installing anything?\n\nYes. Browserless has a hosted endpoint at https://production-sfo.browserless.io and Functionize MCP server at https://mcp.functionize.com/mcp.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/browserless-vs-functionize-mcp.json, and with the fewest tokens: https://www.anchorterminal.com/compare/browserless-vs-functionize-mcp.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"browserless\", \"b\": \"functionize-mcp\"}`.
