Do I need to build my own SP-API app to use AI?
No. Using a managed Amazon MCP handles the OAuth, token refreshes, and API request handling for you, allowing you to connect AI clients securely without writing integration boilerplate.
What if I want to build a custom application?
A service for other sellers needs an appropriate public SP-API application and seller authorization. Evaluate the provider model, permitted data use and Amazon requirements rather than assuming that a private developer app covers outside customers.
