Crate origin_ai 

Inference the application performs itself.

This is the embedded half of Origin’s AI story, and it has nothing to do with MCP. The two are deliberately separate (ADR-0027):

                         ┌── MCP server   external AI controls the app
UI ── Application Core ──┤
                         └── AIService    the app performs inference itself

Using MCP as a general inference API would be the wrong abstraction: the protocol connects a client to a server’s tools, not an application to somebody’s model subscription.

Domain code depends on AiService, never on a provider. A product without the capability simply has no service, and every AI feature it has is off — which is the point: nothing an Origin application does may depend on a model being reachable.
