Design
Voice to recipes: Alexa calls backend, backend calls MCP
Two-part repo: recetario-mcp (Python/FastAPI) and backend-alexa (Node.js). Flow: Alexa Lambda → backend-alexa → recetario-mcp → Brave/scraping. Backend exposes /api/mcp/recipes, ingredients, etc.
Visual style: Distributed architecture, voice as interface
MCP + Alexa backend
recetario-mcp on port 8012, backend-alexa on 3001.
Render deployment
Two web services: one for MCP, one for backend.
Environment variables
BRAVE_API_KEY, MCP_BASE_URL to link services.
