AUTO411 Vehicle Intelligence

simonwakelin/411-vehicle-data-mcp

Production automotive intelligence for AI agents. AUTO411 resolves vehicle identity before returning facts, so agents can distinguish a confirmed vehicle configuration from an ambiguous one rather than guessing. Capabilities include vehicle resolution, specifications, NHTSA safety data, EPA efficiency data, and fitment where licensed and available. Supports VIN and year/make/model workflows with explicit resolution states such as MATCHED_SINGLE, NEEDS_IDENTITY, NO_MATCH, and UNAVAILABLE. Connect AUTO411 to your AI at 411specs.com. Powered by the 411 Vehicle Data API (autoapi411.com)
