# 1. Clone and configure
git clone https://github.com/rohith1125/sentinel-execution-mcp.git
cd sentinel-execution-mcp
cp .env.example .env          # defaults work out of the box — no edits needed

# 2. Start Postgres + Redis + engine (runs migrations automatically)
docker compose -f docker/docker-compose.yml up -d db redis engine

# Wait ~10 seconds, then verify the engine is healthy:
curl http://localhost:8100/health
# {"status": "ok", "provider": "mock", ...}

# 3. Build the MCP server (one-time)
cd packages/mcp
npm install
npm run build

git clone https://github.com/rohith1125/sentinel-execution-mcp.git
cd sentinel-execution-mcp
cp .env.example .env
# Default values work for local paper-trading development — no edits required

cd packages/engine
python3.12 -m venv .venv
source .venv/bin/activate        # Windows: .venv\Scripts\activate
pip install -e ".[dev]"

# From packages/engine with the venv active
alembic upgrade head

uvicorn sentinel.api:app --reload --port 8100

curl http://localhost:8100/health
# {"status": "ok", "env": "paper"}

cd packages/mcp
npm install
npm run build
npm run dev     # stdio transport — for direct Claude Desktop integration
