Agent Brain CLI

Command-line interface for managing AI agent memory and knowledge retrieval with the Agent Brain RAG server.

Agent Brain (formerly doc-serve) is an intelligent document indexing and semantic search system designed to give AI agents long-term memory. This CLI provides a convenient way to manage your Agent Brain server and knowledge base.

PyPI version Python 3.10+ License: MIT

Why Agent Brain?

AI agents need persistent memory to be truly useful. Agent Brain provides the retrieval infrastructure that enables context-aware, knowledge-grounded AI interactions.
