get_option_snapshot
AI agents call get_option_snapshot to retrieve information from Alpaca MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The name suggests fetching a snapshot of option market data (prices, Greeks, volumes, etc.), which is a read-only operation with no side effects. However, severity is elevated to medium because option market data can inform financial decision-making and AI agents could act on stale/misinterpreted snapshot data.
From the tool's definition Tool name 'get_option_snapshot' indicates retrieval of market data snapshot; no description provided but name pattern follows read-only market data access tools like 'get_account_info' and 'get_asset_info' on the same server.
