The Seller Assistant MCP Server gives AI assistants access to the full Seller Assistant API – product data, profit calculations, restrictions, sales estimates, FBA shipments, internal products, suppliers, and more. Everything available through the API is accessible through the MCP server, without switching tools or writing code.
Getting API Token
Before connecting, generate an API token in your Seller Assistant account. Go to Integrations page, chose API and create a new token. Keep it – you'll need it when setting up the connector in AI assistant.

Using MCP Server
Ask the assistant in natural language – it selects the right operation, constructs the call, and returns the result directly in chat. The assistant uses five tools to interact with the API:
sa_search_endpoints – find available API operations by keyword, path, or category
sa_get_endpoint – retrieve full details and parameter schema for a specific operation
sa_list_schemas – browse all available data schemas with optional filtering
sa_get_schema – get the full definition of a specific schema
sa_call_endpoint – execute an API call and return the result directly in chat
Everything available through the Seller Assistant API is accessible via MCP. This includes:
Product data, pricing, restrictions, and sales estimates by ASIN
UPC/EAN ↔ ASIN conversion
Profit calculation with custom COG and logistics inputs
Keepa product data and historical stats
FBA inbound shipments and inventory
Internal products and suppliers – search, create, update, delete
Supplier offers, external identifiers, listings, and product history
