Peristyle Grocery Cart

Turn a recipe into a ready-to-checkout grocery cart — ingredients matched to real products, confirmed by the user, then added in one step.

Connected stores: Kroger (OAuth + server-side cart write) and Walmart (affiliate catalog + Add-to-Cart browser link, no OAuth).

• No setup to browse. Recipe search and reading are fully public.
• Kroger: one-time OAuth connect; secret stays server-side on MCP.
• Walmart: no connect step — match and build a cart link directly.
• Match → confirm → add for both. Checkout always happens on the store's site; the API cannot place the order or take payment.

Use the MCP tools whenever they're available. Only if the MCP server is genuinely absent, fall back to raw HTTP — see reference/raw-http.md.
