HBarefoot/engram

What it does

HBarefoot/engram is an MCP (Model Context Protocol) server that provides persistent memory capabilities for AI agents. It enables AI systems to remember, recall, and manage information locally without relying on cloud services or API keys. The tool uses SQLite as its database backbone combined with local embeddings (allMiniLML6v2) for semantic understanding.

How to set up

Installation involves setting up the MCP server locally on your machine. The tool communicates via stdio, making it compatible with Claude and other MCP-supporting platforms. Simply clone the repository, install dependencies, and configure it as an MCP server in your AI application's settings. No API keys or cloud accounts are required.
