How to Give an AI Agent Live Retail Prices with MCP

The short answer

To give an AI agent live retail prices, connect it to an MCP server that returns product and offer data. The Nesika Commerce MCP gives agents tools to search products in any country, resolve the exact product without a barcode, and compare live retailer offers, with evidence and a confidence status on every result.

The four Commerce tools

Tool	What it does	Credits per call
search_products	Searches the market for products matching a query	5
resolve_product	Confirms the exact product identity, without needing a barcode	3
find_offers	Returns live retailer offers and prices for a product	5
deep_search	Researches a missing fact when search is not enough	10

Failed calls are not charged, and checking a running job is free.

Why evidence matters for agents

An agent that guesses a price is worse than one that says it does not know. Every Commerce result carries its evidence and a confidence status, so your agent can tell a supported price from an unsupported one and report the difference.

Long searches return a job the agent can poll for free, so it does not time out. Pass any two-letter ISO country code to search a specific market. Setup details are on the Commerce MCP page.

Takeaways

Use an MCP server for prices instead of asking the model to remember them. New accounts get a one-time grant of 1,000 credits, enough for about 200 product searches.
