    Open Clinic Procurement (OCP)

    An open MCP standard that lets clinic software and AI assistants search, compare and order directly at suppliers – on the clinic's own terms, without a middleman.

    The problem

    Clinics order from many suppliers: through web shops, PDF order forms, e-mail and phone. Every supplier has its own system. Today, clinic software and AI assistants cannot order anywhere directly – comparing prices and checking availability is still manual work.

    The idea

    An open standard. Each supplier runs a small MCP server (Model Context Protocol) with four uniform functions. Any clinic software and any AI assistant – Viali, Claude, ChatGPT – can then search, get an offer and order directly at the supplier. With the clinic's customer account and its own terms.

    Four functions

    The four functions

    1. 1.Search products

      By GTIN, Pharmacode, manufacturer reference (REF) or name.

      Example: “nitrile disposable gloves, size M”

    2. 2.Offer for this clinic

      Price after discount, pack size, availability, delivery time.

      Example: “ECG electrodes, 50 per bag, €7.55, in stock”

    3. 3.Place an order

      Lines, delivery address, the clinic's customer number.

    4. 4.Order status

      Confirmed, shipped, delivered, back order.

    Rules

    The rules

    • Open and free: Anyone may use and implement the standard.
    • Unique products: Identification by GTIN or Pharmacode.
    • Own customer account: The clinic signs in with its account at the supplier (OAuth). Its prices and terms apply.
    • Never patient data: Orders contain only products, quantities and the clinic's addresses.
    • The supplier keeps control of its data: Prices, terms and the customer relationship stay with the supplier. No middleman, no commission.
    For suppliers

    Why it pays off for suppliers

    • Orders come straight from the clinic's software and its AI assistant.
    • No extra portal to maintain.
    • No middleman, no commission, no lock-in.
    • Works with Viali, Claude, ChatGPT and any software that implements the standard.
