Get all available options (values) for a Flag. Shows Value IDs needed for updates.
AI agents call ffs_get_flag_options to retrieve information from FFS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves flag configuration options without altering any data. It is purely informational, supporting users in understanding available flag values before making updates through other tools. The low severity reflects minimal blast radius if misused - an AI agent can only read flag metadata, not modify system state or access sensitive user data.
From the tool's definition Tool description states 'Get all available options (values) for a Flag' - a retrieval operation with no modification.
