"Instacart" matching MCP servers:

Enables real-time out-of-stock grocery cart substitutions by enforcing dietary constraints, unit price delta ceilings, and brand affinity scoring to select suitable replacement products.

This MCP server enables agents to handle real-time out-of-stock grocery items by scoring candidate replacements against dietary constraints (vegan, gluten-free, organic), unit price delta ceilings, and brand affinity. It returns a deterministic substitution verdict with the chosen replacement, so carts can be repaired automatically without human intervention.
