VerifiedStreamable HTTPWeb executableBusiness & Commerce

Overview

AI-generated overview

Lets an assistant run UK used-car checks against MOT history and mileage records and test an advert's claims.

What it does
RegTail is a remote MCP endpoint for UK used-car checks. It lets an assistant look up MOT history and mileage records and compare an advert's stated claims against those records. The manifest does not list individual tools, so the exact operations are not documented here.
When to use it
Useful when evaluating a UK used car listing and you want an assistant to check MOT history, mileage, or advert claims against the records. It is aimed at buyers, dealers, or anyone vetting a vehicle before purchase.
Requirements
A remote streamable HTTP endpoint at regtail.com; no local package or runtime is needed. It requires an Authorization header containing a Bearer token with a RegTail API key (rt_...). A public sample key returns one sample car for free; a full key is obtained from a RegTail account.
Before you install
The Authorization header carries a secret API key, so treat it as a credential and avoid exposing it. The public sample key is limited to one sample car. The manifest declares no other credentials, payments, or write actions, but the exact tools are not listed, so confirm what data is sent to RegTail before use.
