Instructions

Search the graph memory for relevant facts.

Args:
    query: The search query
    group_ids: Optional list of group IDs to filter results
    max_facts: Maximum number of facts to return (default: 10)
    center_node_uuid: Optional UUID of a node to center the search around

Returns:
    List of fact dictionaries containing search results

Example:
    search_memory_facts(
        query="implementation dependencies",
        group_ids=["knowledge-smith"],
        max_facts=10
    )

  MCP tool handler for 'search_memory_facts'. Registers the tool via @mcp.tool() and delegates to graphiti_tools.search_facts_impl.

  Core implementation of search_memory_facts logic. Creates GraphitiClient and calls client.search_facts to perform the graph search.
