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**TinyFish.** OpenAPI documents are published for five APIs, errors carry typed codes and request IDs, and Search and Fetch are free within daily allowances. The terms let Tiny Fish train its models on customer data, run creation takes no idempotency keys, and the status page shows an hour or more of downtime on several days for the Browser and Search APIs.\n\n## Before you call either\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### TinyFish\n\n1. Check `result` as well as `status`. A run can be `COMPLETED` while the goal failed, with `result.status` set to `failure`\n2. Don't retry `POST /v1/automation/run` blindly after a timeout. There are no idempotency keys, so list runs first to avoid duplicates\n3. Use `/v1/automation/run-async` or `/run-sse` when a run may need cancelling. Runs started with the synchronous endpoint can't be cancelled\n4. Allow 60 seconds for Browser session creation, connect Playwright to `cdp_url` (not `base_url`), and `DELETE` the session when done because billing is per minute\n5. Never put passwords in `goal`, which is logged. Pass `use_vault: true` with `credential_item_ids`, or `use_profile: true` for saved login state\n\n## Questions\n\n### Which is better for AI agents, Functionize MCP server or TinyFish?\n\nTinyFish scores 67.7 (B) on agent readiness against Functionize MCP server's 44.7 (E), and leads in 6 of 7 scored categories.\n\n### Do Functionize MCP server and TinyFish need an API key?\n\nFunctionize MCP server uses an OAuth sign-in. TinyFish takes an API key or an OAuth sign-in.\n\n### Can an agent call Functionize MCP server and TinyFish without installing anything?\n\nYes.
