The Open Source Drop Lens
Gives your AI assistant persistent memory via a local knowledge graph. It stores entities, relationships, and observations in a JSON file that survives between sessions. The model can remember context about you, your projects, and your preferences.
You get entity creation, relationship mapping, and observation tracking. Data lives in a local file you control. No cloud, no API keys, no external dependencies. Completely free.
Maintained by the official Model Context Protocol team. If you want your AI to build up context over time instead of starting fresh every session, this is the simplest path. Lightweight and effective.
