List all possible advisory states in the Errata Tool.
AI agents call list_errata_states to retrieve information from Errata Tool MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and enumerates reference data (advisory states) from the Errata Tool without creating, modifying, deleting, or executing any operations. It is a read-only query with minimal blast radius—listing valid states is informational only and cannot be misused to cause harm.
From the tool's definition Tool name 'list_errata_states' and description 'List all possible advisory states' indicate a query operation that retrieves static metadata about advisory states with no side effects.
