The tool is priced at $0.01 per call with 25 free calls per day on a free API key, which agents can obtain in-session via a get_api_key MCP tool. The developer says the aim is to address cases where trading agents treat options like stocks and miss broker-specific rules.", "body_md": "Most trading agents treat an option like a stock with a funny price. Brokers don't. Three things catch agents out:\n\nThen 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.\n\n`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).\n\nMCP: [agent-financial-advisor.agent-financial-advisor.workers.dev/mcp?src=devto2](https://agent-financial-advisor.agent-financial-advisor.workers.dev/mcp?src=devto2)\n\nExamples: [github.com/mytomclinic/agent-financial-advisor/tree/main/examples](https://github.com/mytomclinic/agent-financial-advisor/tree/main/examples)", "url": "https://wpnews.pro/news/your-options-agent-will-get-assigned-on-a-friday-it-didn-t-plan-for", "canonical_source": "https://dev.to/agentriskdesk/your-options-agent-will-get-assigned-on-a-friday-it-didnt-plan-for-1agl", "published_at": "2026-10-31 19:42:24+00:00", "updated_at": "2026-10-31 19:52:01.680220+00:00", "lang": "en", "topics": ["ai-agents", "ai-tools", "developer-tools", "agent-protocols"], "entities": ["FINRA", "options_risk_check", "agent-financial-advisor", "get_api_key", "MCP"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/your-options-agent-will-get-assigned-on-a-friday-it-didn-t-plan-for", "markdown": "https://wpnews.pro/news/your-options-agent-will-get-assigned-on-a-friday-it-didn-t-plan-for.md", "text": "https://wpnews.pro/news/your-options-agent-will-get-assigned-on-a-friday-it-didn-t-plan-for.txt", "jsonld": "https://wpnews.pro/news/your-options-agent-will-get-assigned-on-a-friday-it-didn-t-plan-for.jsonld"}}
