    How to connect

    How to connect Loppee to Claude

    The server address to paste into Claude settings:

    https://loppee.com/mcp/discovery

    1. Open Claude (claude.ai or the desktop app).
    2. Go to Settings → Connectors.
    3. Click Add custom connector.
    4. Paste the server address copied below into Remote MCP server URL and click Add.
    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:

    https://loppee.com/mcp/discovery

    1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
    2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
    3. Open Settings → Connectors and click Create.
    4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
    5. Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
    6. In a new chat open + → Apps/Connectors and enable the connector.

    lookup_businessUse this when the user names a business and wants its Loppee Registry match. Returns exact and genuine-prefix name matches with stable ids, coarse public city/state, and truthful Verified, Listed, or Registry disclosure. It does not perform category discovery, accept or return caller location, or return a street address or ZIP.
    get_trust_cardUse this when a business is already identified and the user wants its public Loppee Trust Card. Returns the exact business status, disclosure, coarse public city/state, public facts, review context, and citation without account authority, street address, ZIP, or signed media links.
    get_business_reviewsUse this when the user wants the public customer reviews for one Loppee business id. Supports pagination and star-rating filters, preserves reviewer and interaction labels, masks reviewer identity, and changes nothing.
    explain_recommendationUse this when the user asks why a known published business is or is not recommendable on Loppee. Returns the published class, disclosure, recommendation basis, commercial-neutrality statement, and citation without exposing private weighting.
    compare_businessesUse this when the user wants a side-by-side comparison of two to twenty known published Loppee business ids. Returns each business's exact class, disclosure, review context, and citation; unknown or unavailable ids are listed as unresolved rather than fabricated.
