Memorys MCP

A persistent memory MCP server written in Rust that provides AI agents with a knowledge graph for searching, reasoning, and correction. It supports episodic memory, contradiction detection, and prospective triggers, backed by PostgreSQL and pgvector, aiming to prevent agents from forgetting codebases between sessions.
