private-gpt

@zylon-aiPython

Add RAG, files, tools, databases, and MCP APIs to locally hosted language models.

Project overview

PrivateGPT sits between an OpenAI-compatible local inference server and the applications built on top of it. Its API covers messages, file ingestion, citation-backed retrieval, custom tools, database and CSV access, and MCP connectors, following the Claude API as a reference. The included web interface is mainly a demonstrator and debugger; developers are expected to build their own user experience around the API.

It covers identity and data management, file storage, server-side functions, realtime communication, and web hosting. Teams can use the managed cloud or self-host in Docker, Kubernetes, and other container environments, then connect through SDKs or REST, WebSocket, and GraphQL APIs.
