The AI-Native Database: JSON + Vectors + MCP
Project description
CourierDB
CourierDB is a JSON-based database stack that is AI-Native.
It's core objective is to be fast, simple, and n8n + AI optimized.
Core Features
- JSON (No-SQL)
- API controlled for n8n-usage and database safety
- API Key protected
- Dockerized for ease of use
- MCP server for Agentic use
- Vectorization built in (BYOK)
- Client CLI and PyPi package
- Speed: Built on LMDB (Lightning Memory-Mapped Database) and USearch (HNSW Vector Search).
Guidelines
CourierDB is intentionally built to be fast, simple, and AI-Native. It is NOT ideal for compliance applications such as FinTech because it lacks SQLs ACID safety measures.
CourierDB is ideal for AI applications, automation, speed, and n8n workflows.
