WHAT IT DOES

What find_options does on Open Stocks MCP

AI agents call find_options to retrieve information from Open Stocks MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why find_options is rated Low

This tool searches and filters options data to present available tradable contracts. It has no side effects—it does not execute trades, modify positions, delete data, or commit financial obligations. While the server context involves trading capabilities, this specific tool is purely a search/query function that returns filtered market data for user review before any trading decision occurs.

From the tool's definition Tool name 'find_options' and description 'Finds tradable options with optional filtering' indicate a query/search operation that retrieves data about available options contracts.

find_options Allowed

find_options is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
