The story
Kacper sells PC components and gaming peripherals. His catalog refreshes constantly as new generations launch, and his product pages carry manufacturer spec sheets that answer the question a specification asks rather than the question a builder asks.
His customers are assembling a system. They search whether a card fits a case, whether a cooler clears the RAM, whether a power supply is sufficient, whether a socket matches. Every one of those is answerable from specs he already has and none of it was written down.
He connected the catalog to his assistant over MCP and now runs a build-context pass on every new generation, rewriting compatibility language and refreshing FAQ schema across a hundred products in a single prompt.
