amazon-seller-mcp is an MCP (Model Context Protocol) server for Amazon sellers, used to connect Amazon Seller Central operational actions into Claude Desktop, enabling AI-assisted inventory management, fee calculation, and listing optimization through SP-API.
In terms of purpose, this project aims to let sellers complete daily operational tasks with the help of conversational AI, such as obtaining inventory recommendations, calculating FBA-related fees, analyzing sales data, and optimizing product listings. It is not a standalone seller backend, but rather runs as an extension tool for Claude Desktop, providing tool invocation capabilities through the MCP protocol.
Main capabilities include: interacting with Amazon Seller Central through SP-API; inventory management, including obtaining inventory status and recommendations; fee calculation, covering 2026 FBA fulfillment fees (by size tier), monthly storage fees (seasonal rates), long-term inventory surcharges (12-15 months and over 15 months), low-inventory-level fees, and attention to GET call fees (after April 2026); listing optimization-related operations; sales data analysis. The project also includes a built-in caching mechanism to reduce API costs: inventory data is cached for 30 minutes, and product data is cached for 24 hours.
How to use: dependencies need to be installed first, then a .env file must be created to configure credentials, next the connection should be tested, and finally the MCP server should be run. After configuration is complete, operations such as inventory recommendations can be requested in Claude Desktop. The project references SKILL.md to provide detailed tool documentation, but the specific tool list is not fully expanded in this material.
Applicable scenarios: suitable for Amazon sellers, especially sellers operating multiple marketplaces at the same time, who want to use an AI assistant to automate or semi-automate repetitive tasks such as inventory monitoring, fee estimation, and listing maintenance. Supported marketplaces include the United States, Canada, Mexico, Brazil, the United Kingdom, Germany, France, Italy, Spain, the Netherlands, Japan, Singapore, and Australia.
Limitations and missing information: the current version is 1.0.0. The material does not provide specific installation commands, dependency lists, complete field descriptions for the .env file, a specific list of tool functions, API permission requirements, pricing or charging information, or usage limits (such as request frequencylimits, etc.). Before use, you need to refer to SKILL.md in the project repository and the official documentation yourself.
