Open-source commerce MCP layer proposal adds spending limits and approval flows for AI purchases
i____eat___ass · reddit · 2026-10-21
A Redditor proposes an open-source commerce-focused MCP server sitting between AI assistants and online stores (starting with Shopify). Instead of letting the model control purchases directly, it would handle product discovery via official APIs, user-defined spending limits, cart-and-price-bound explicit approvals, idempotent workflows with duplicate prevention, and audit logs. Initial version uses official checkout handoff. The author seeks architecture and DX feedback.
