Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

compare

compare_wheels

Compare 2-3 wheels side by side: full specs and prices in every currency each is sold in. Each entry is matched by partial company and model, preferring an available wheel. Entries that match nothing are listed in not_found; the call fails if fewer than 2 wheels are found.

uci

check_uci_approval

Check UCI approval status for wheels matching a company and/or model (partial matches). At least one of company or model is required. Returns up to 20 matching wheels, each with its stored UCI Approved value (Yes / No); a blank value means not yet checked, not "not approved".

wheel

get_wheel_price

Get current pricing and specs for one wheel by company and model. Prefers an available match; a discontinued wheel is returned (flagged, with last-known prices) when it is the only match.

wheels

search_wheels

Search wheels with filters. At least one filter is required. Covers currently-available wheels unless include_discontinued is set; every result carries "Available". Returns up to 20 results per call.

The Wheel Atlas — questions

Answers built from our own checks of this server.

What can The Wheel Atlas do?

It exposes 4 tools, read directly from the server on our last check. Among them: check_uci_approval, compare_wheels, get_wheel_price, search_wheels. 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 The Wheel Atlas working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 85 of 91 checks got a reply (93.4%), average response time 422 ms. The bar chart above shows every period we have measured.

How do I connect The Wheel Atlas?

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 The Wheel Atlas need an API key?

No. The Wheel Atlas completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is The Wheel Atlas?

It answers our handshake in 422 ms on average, which is faster than 39% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
