Memrust is an open-source memory engine for AI agents built in Rust. Instead of treating memory as just vector search, it combines semantic search, BM25, entity graphs and recency-aware ranking to retrieve information the way agents actually need it. With agent-native APIs like remember(), recall() and forget(), built-in memory lifecycle management, multi-agent support, MCP integration, and Python, TypeScript and Rust SDKs, memrust gives AI agents a true memory layer-not just a vector database.
