memory_forget
AI agents call memory_forget to permanently remove resources in Hippocampus Memory MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The name 'memory_forget' on a persistent memory storage server strongly implies the removal/deletion of stored memories. Given the server's description of 'intelligent forgetting' as a feature, this tool likely permanently removes memory entries from the FAISS index and storage, which would be irreversible. Sibling tools (memory_read, memory_write, memory_consolidate) confirm this is the deletion counterpart.
