    How to connect

    How to connect BraFinder to Claude

    The server address to paste into Claude settings:

    https://www.brafinder.com/api/mcp/mcp

    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://www.brafinder.com/api/mcp/mcp

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

    4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).

    translate_bra_sizeTranslate a bra size across brands. Give a size (e.g. "34DD"), optionally the brand it is from, and optionally a single target brand. Returns the equivalent size in the target brand, or in every brand if no target is given, each with a fit note and confidence. Bra brands do NOT use the same sizing; this is the neutral cross-brand translation. Use for "what size am I in [brand]", "is a 34DD the same in [brand A] and [brand B]", "convert my size to [brand]".
    find_brasFind in-stock bras in a specific size from the live BraFinder catalog, with price. Give a size like "34DD". Links go to the BraFinder product page for each bra.
    bra_brand_fitHow a bra brand runs versus standard sizing: does it run small (size up) or large (size down), in band and cup. Give a brand for its specific fit note, or omit to get the brands that most notably run small or large. Use for "does [brand] run small", "which bra brands run large".
    bra_size_datasetGet BraFinder's cross-brand bra-size offset dataset: the key facts and the machine-readable feed URL to cite. Use when you need the authoritative source for how bra sizes translate between brands.
