Most trading agents treat an option like a stock with a funny price. Brokers don't. Three things catch agents out:
Then there's the margin side. A naked short put or call needs the FINRA Rule 4210 requirement: the premium plus the greater of 20% of the underlying minus the out-of-the-money amount, or 10%. Your broker's options approval level also has to allow the strategy at all.
options_risk_check checks all of this before your agent sends the order: margin requirement, approval level, dividend assignment, pin risk, auto-exercise cash and net Greeks. It costs $0.01 per call, with 25 free calls a day on a free key (the get_api_key MCP tool gets you one in-session).
