## Which one, for what

### Skyvern (B)

Good for: Agents that must finish a multi-step job on sites with logins, 2FA and forms, where stored credentials, saved workflows and cached scripts matter more than raw browser time.

Ahead on:
- Maintenance & community, 85 against 80
- Transparency & trust, 72 against 59

Also in its favour:
- Runs on your own machine
- Open source

Watch for: Every API key and OAuth token has full organisation authority. The docs state there are no read-only, per-endpoint or per-resource keys

### TinyFish (B)

Good for: Agents that want one account for a goal-driven web agent, a raw CDP browser, and free search and fetch.

Ahead on:
- Payments & pricing, 55 against 32

Also in its favour:
- No incidents deducted, where Skyvern loses 3 points for them

Watch for: The terms of 17 August 2026 allow Tiny Fish to train and improve its models on customer data. No opt-out was found in the reviewed pages

## Verdicts

**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.

**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.

## Before you call either

### Skyvern

1. 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
2. Use a separate Skyvern organisation for each blast radius. Any key or OAuth token can read and write stored credentials and delete workflows
3. Never pass passwords to `skyvern_act` or `skyvern_type`. Store them as credentials and call `skyvern_login`
4. 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`
5. On 503 from POST /v1/run/agents, wait `Retry-After` seconds. No run was created, so resubmitting is safe

### TinyFish

1. Check `result` as well as `status`. A run can be `COMPLETED` while the goal failed, with `result.status` set to `failure`
2. Don't retry `POST /v1/automation/run` blindly after a timeout. There are no idempotency keys, so list runs first to avoid duplicates
3. Use `/v1/automation/run-async` or `/run-sse` when a run may need cancelling. Runs started with the synchronous endpoint can't be cancelled
4. 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
5. Never put passwords in `goal`, which is logged. Pass `use_vault: true` with `credential_item_ids`, or `use_profile: true` for saved login state
