rwnalds/engram

What it does

Engram is an MCP server that provides AI agents with a persistent, version-controlled knowledge base built on markdown files. It enables agents to read and write to a centralized vault while maintaining full git history. The tool features authority-aware search that ranks active notes above archived or superseded ones by analyzing frontmatter metadata, ensuring agents always reference current information rather than outdated content.

How to set up

Clone the rwnalds/engram repository from GitHub. Install dependencies and configure your git repository for the markdown vault. Set up per-agent access tokens to control read-only or write permissions for different agents. Connect the MCP server to your AI agent platform and point it to your vault location.
