    AI Shopping tools for product search, comparison, and safe checkout

    Commerce Gateway — an infrastructure layer that enables open-source AI agents to participate in agentic commerce through the Universal Commerce Protocol.

    Our platform gives agents a hosted UCP profile registry, a secure MCP gateway, and access to commerce flows without requiring every agent to own a domain, GitHub account, or Shopify credentials.

    With this solution, agents can discover products, recommend options, build carts, validate them with the user, and generate checkout handoff links where the buyer completes payment safely on Shopping platform.

    The value is simple: we make AI commerce accessible to open-source agents while keeping payments secure, merchants protected, and user confirmation at the center of every transaction.

    Requires a local install: run the server on your machine, then point your client at it.

    How to connect

    How to connect UCP Gateway to Claude

    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.

    Authorization

    After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

    This server runs locally: it is wired up through the client config, and the project documentation carries the steps.

    How to connect UCP Gateway to ChatGPT

    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.

    OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.

    Authorization

    On first use ChatGPT opens the service's sign-in window. Sign in and approve access.
