Ollama

A proof-of-concept that layers authentication, encryption, and multi-agent coordination onto MCP — with four security tiers from API keys to enterprise OAuth2 with audit trails.

An open-source demo that coordinates multiple AI agents using only PostgreSQL — pgmq for task queuing, LISTEN/NOTIFY for event-driven coordination, ltree for lineage tracking. No Redis, no Kafka, no vector database.

An open-source semantic layer that lets you query PostgreSQL in plain English using local LLM inference via Ollama. No API keys, no cloud — just your database and a local model.
