None at the broker
What it means: no broker-side approval step is documented. Guardrails, if any, are in software you control.
Examples
- Alpaca: the CLI has no confirmation prompts and every command executes immediately.1 Paper trading is available for testing.2
- Webull local OpenAPI MCP: places, modifies and cancels orders directly, with configurable notional limits, quantity limits and a symbol whitelist in the server you run.3
Builder notes
- Put a human-in-the-loop step in your own client before live orders. See Human-in-the-loop patterns.
- Start on paper or sandbox endpoints where they exist.43
