Engram MCP

Engram is a self-hosted Model Context Protocol server that provides shared, long-term memory for AI agents like Claude Code, Cursor, and Hermes. It uses a git-backed markdown vault as the source of truth, eliminating the need for a vector database. The server supports markdown RAG, allows agents to read and write notes, and includes a dashboard for searching the vault and viewing per-file diffs. It features a mechanism to mark facts as superseded or expired, ensuring search results reflect current truth rather than just semantic similarity.
