Mnemo

Mnemo MCP Server is an open-source Model Context Protocol (MCP) server that delivers persistent AI memory with hybrid search, embedded entity resolution, and encrypted multi-machine sync. Built for developers and researchers, Mnemo enables AI agents and applications to capture, retrieve, compress, and synchronize structured memories, facts, and decisions, leveraging a hybrid vector/full-text retrieval system, automated semantic deduplication, and a temporal knowledge graph. It can be self-hosted, requires no API keys to run locally, and offers robust archiving, encryption, and plugin architecture for integration with broader AI toolchains.
