Gemdex MCP

Gemdex is a persistent memory layer for AI coding agents that allows saving, recalling, and updating memories across repos and sessions. It uses Gemma embeddings and embedded LanceDB for hybrid semantic and BM25 retrieval, enabling agents to index small chunks and resolve matches to whole parent memories for precise context retrieval.
