What is the Model Context Protocol?

MCP is an open standard that lets AI assistants like Claude and ChatGPT securely connect to live data sources. Instead of the assistant guessing at fuel prices from months-old training data, it calls the Fuel Checker server and gets today's actual pump prices for more than 8,400 UK forecourts - the same data behind our live map, refreshed daily from the Government's open-data scheme.

That turns everyday questions into grounded answers: “where's the cheapest diesel near M1?”, “plan me a route from Leeds to Manchester with the best fill-up stop”, or “what will this 600-mile week cost in fuel at 45 mpg?”. The assistant picks the right tool, we return live structured data, and it answers with real numbers - prices, distances, and the pounds saved versus the UK average.

The essential tools are free - no account or token needed. Route planning and price-trend tools come with Plus and Business plans, using a personal access token you paste in once during setup. Tokens can be revoked at any time from your account, and the server only ever sees the questions your assistant asks it - never your conversation.
