Get facts
AI agents call graphiti_get_facts to retrieve information from Garza Home MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves facts from the knowledge graph (Graphiti) without creating, modifying, deleting, or executing any operations. It is a straightforward data retrieval operation with no side effects. The low severity reflects minimal risk if misused by an AI agent, as it only exposes existing information.
