MCP for merchants: let AI agents shop and check out on your store
Agentic commerce is going mainstream worldwide. The Model Context Protocol (MCP) is becoming the standard way AI assistants call external tools, and merchants everywhere are starting to expose their catalogs to shopping agents. OrderCore lets any merchant, anywhere, become shoppable — and checkout-able — by AI agents, and adds the hard part most keep off the agent: safe, idempotent checkout.
The shift is already shipping
This isn't hypothetical. AI platforms are pushing agent commerce (OpenAI and Anthropic are both building agent + tool ecosystems), payment providers ship agent toolkits, and several retailers have started exposing MCP servers so an assistant can search products and build a cart. The common pattern: they let agents shop, but keep the final checkout on their own site.
What OrderCore gives any merchant
OrderCore is a commerce API and MCP server you point at your catalog. Your store becomes shoppable — and checkout-able — by AI agents, without building the backend:
| Capability | Roll your own | OrderCore |
|---|---|---|
| Catalog + product search for agents | Build and expose it | Catalog API, ready to expose as tools |
| Cart / checkout session | Build session state | create_checkout_session |
| Agent completes the order | Kept on your website | complete_checkout_session — idempotent per session |
| No duplicate order on retry | Keys + dedup + edge cases | Built in |
| MCP + multi-model schemas | Per-model schema work | MCP server + OpenAI/Claude/Gemini/DeepSeek/Grok schemas |
Who this is for
- D2C brands and shops that want to be shoppable by AI assistants without a platform migration.
- Marketplaces and catalogs that want an agent-facing interface fast.
- Teams building shopping agents that need a real, idempotent checkout backend, not just a payment call.
