mot_reliability

Real UK MOT failure data for a used car: per-category failure rates (overall and at a given mileage) and the riskiest components with typical failure mileages. Use whenever a user is buying, comparing or maintaining a used car sold in the UK. Data is aggregated from official DfT MOT test results — real outcomes, not estimates. Responses carry a whatbreaks.uk attribution line.

mot_vehicle_search

Search the covered vehicles (530 UK model generations) by free text. Use to check coverage or disambiguate before calling mot_reliability.

Whatbreaks Mot — questions

Answers built from our own checks of this server.

What can Whatbreaks Mot do?

It exposes 2 tools, read directly from the server on our last check. Among them: mot_reliability, mot_vehicle_search. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Whatbreaks Mot working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 17 of 92 checks got a reply (18.5%), average response time 354 ms. The bar chart above shows every period we have measured.

Is Whatbreaks Mot still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

The registry lists Whatbreaks Mot as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect Whatbreaks Mot?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Whatbreaks Mot need an API key?

No. Whatbreaks Mot completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Whatbreaks Mot?

It answers our handshake in 354 ms on average, which is faster than 38% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
