# AlphaBrief API

FastAPI + LangGraph supervisor-pattern multi-agent service with an MCP tool server,
deterministic numeric verification and a human-in-the-loop approval gate.

Full documentation lives in the repository root `README.md`. This file exists so the
package metadata (`pyproject.toml` → `readme`) resolves during an editable install.
