1. Create a virtual environment:
cd src
uv venv
source .venv/bin/activate # On macOS/Linux
uvicorn main:app --reload
MCP_AUTH_TOKEN="test_token_local_dev" uvicorn main:app --reload
The server will start on http://localhost:8000 by default.
- Azure CLI installed (az)
- Azure Developer CLI installed (azd)
- Azure subscription
1. Login to Azure:
