Agent-ready commerce: letting buyers’ AI shop through MCP

Shoppers already ask AI assistants to find products, compare options and reorder supplies. Increasingly those assistants will complete the purchase too. A storefront built only for human eyes is invisible to them. That is why we built agent-ready endpoints into Commerce 360.

What an agent needs from a store

• Structured catalogue access: products, variants, stock and prices in a form a model can query, not scrape.
• Quotes and carts as actions: create a cart, apply terms, get a total including tax and shipping.
• Clear authority: who the agent acts for, what it is allowed to spend, and when a human must confirm.
• Auditability: a record of what the agent asked, what it was told and what it bought.

Why MCP

The Model Context Protocol gives AI assistants a standard way to discover and call tools. Exposing the store as MCP tools — search, quote, order, track — means any compatible assistant can use it without a custom integration. We pair that with a commerce protocol layer for the transaction itself, so payments and order state follow the same rules as every other channel.

Guardrails matter more than features

An agent with a payment method is a new kind of risk. Spending limits, confirmation thresholds, scoped tokens and anomaly checks are not optional extras; they are what make a merchant comfortable switching the channel on. We handle agent identity and permissions with the same gateway approach we use internally — Monarch AgentGate — so every call is attributable and revocable.

One order desk for every channel

Orders from web, chat, voice and AI agents land in the same order desk with the same fulfilment, returns and reporting. Operations teams shouldn't need to know which channel a buyer used to serve them well — only that it was authorised.

Getting ready

Start by making your catalogue and pricing available through a clean, documented API. Decide your policy for agent purchases — limits, confirmations, which customers may use them. Then expose a small set of tools and watch how assistants use them. The merchants who learn this early will set expectations for everyone else.
