Akeneo is a PIM. The title, the attribute, the image, and the locale live there, and each channel needs a different slice of that record.
Products, attributes, families, locales, and the assets.
The PIM product comes in as the content source on the SKU row. Channel listings stay attached to it.
A rewritten title for one marketplace can go back to Akeneo as the channel value, or out to the channel, when that write is in scope.
Whether Akeneo is the content source, who may publish a locale, and which channels read from it today.
An API is the door the system opens for orders, stock, and listings. An MCP server is a tool surface the AI can call, with the same guardrails. The call names who holds the login, which objects are read, and which writes wait for a person.
