Make your Medusa v2 store shoppable by AI agents.

This plugin adds UCP and ACP protocol endpoints to your Medusa backend, so AI shopping agents can discover your products, create checkouts, and complete purchases — through standard HTTP APIs that require no frontend at all.

Get started

• Quick Start — go from npm install to a discoverable store in under 10 minutes
• Architecture — the gateway pattern and how the plugin sits inside Medusa
• UCP and ACP — orientation on the two protocols this plugin speaks

Reference

• Build a Handler — author your own payment handler package
• Authentication — every token in the system, who issues it, and where it goes
• Glossary — terminology

Project status

The plugin is pre-1.0 and tracks two evolving public specs (UCP 2026-04-08, ACP 2026-01-30). Breaking spec changes ripple through both packages as a minor bump until 1.0.

The reference Prism payment handler ships in this monorepo at packages/prism-payment. New handlers (Stripe, Klarna, etc.) live in their own repos and self-register at module load — no PR to this repo needed.
