    How to connect

    How to connect The Wheel Atlas to Claude

    The server address to paste into Claude settings:

    2. Go to Settings → Connectors.
    3. Click Add custom connector.

    5. In a chat, click + → Connectors and switch the new connector on.

    Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

    The server address to paste into ChatGPT settings:

    2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.

    Server tool list (4)

    Raw names from tools/list. Only developers need these.

    search_wheelsSearch 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.
    get_wheel_priceGet 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.
    compare_wheelsCompare 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.
    check_uci_approvalCheck 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".
