note: 'The MCP surface and the OpenAPI surface at Nexar are two DIFFERENT products and do not overlap at all. The
  MCP endpoint is the Shopify storefront for the consumer dashcam shop; the OpenAPI contracts are the CityStream
  road-data APIs on external.getnexar.com. Recording this divergence is the point of the crosswalk: an agent that
  discovers Nexar through MCP can buy a dashcam and read store policy, and cannot reach a single one of the seven
  published CityStream operations.'
