The Seller Assistant MCP Server lets an AI assistant work with specific Seller Assistant operations in natural language without code. It is a standalone set of tools covering price-list analysis, product lookups, selling-restriction checks, purchase orders, suppliers, brand analysis, SKU costs and the repricer.
Before you start
You need a Seller Assistant account. Checking selling restrictions and repricing also need a connected Amazon seller account – the rest works without one.
There is no API key to create and nothing to install: you sign in with your Seller Assistant account, and the AI client never sees your password. Working through the MCP Server uses the same account and the same allowances as the web app and the extension.
Using MCP Server
Ask the assistant in natural language – it selects the right operation, constructs the call, and returns the result directly in chat. What you can do through the MCP server:
Account – read the context of the connected account, including the marketplaces available to it.
Products – look up a product and its data.
Price List Analyzer – list your price lists, start an analysis, check its status, and get the resulting leads.
Restriction Checker – check a single product, start a bulk check, list your checks, follow their status, and get the results.
Purchase Orders – find, create and edit purchase orders, including creating one from the leads of a price list or from a supplier's order file.
Repricer – list the products being repriced and switch them on or off, list, create, edit, delete and assign strategies, set price limits and MAP, and read history and performance.
SKU costs – read and set the costs behind your profit calculations.
Suppliers – list and add suppliers, and search for new ones with AI.
Brand analysis – start an analysis, list your analyses, and read a result.
Product identifiers – save an ASIN and its UPC or EAN as a permanent match for your team.
