…file) Add memory_delete_fact, memory_delete_preference, and memory_delete_entity tools to the extended MCP profile. Uses DETACH DELETE to clean up all relationships. Idempotent — deleting a non-existent ID returns without error. Addresses the append-only limitation where wrong facts, stale preferences, and outdated entities could not be corrected through the MCP interface.

The memory system is append-only — wrong facts, stale preferences, and outdated entities cannot be corrected through the MCP interface. The only workaround is raw Cypher via
graph_query, which is read-only for safety. These tools provide a safe, structured way to clean up graph data.Files changed
