    How to connect

    How to connect Plain Freight to Claude

    The server address to paste into Claude settings:

    https://plainfreight.com/api/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.

    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.

    How to connect Plain Freight to ChatGPT

    The server address to paste into ChatGPT settings:

    https://plainfreight.com/api/mcp

    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.

    generate_offerGet an all-in DDP offer (freight, US customs clearance, duties, and US door delivery in one USD number) for a shipment from China to the USA, 100 g to 2,000 kg. Prices come from Plain Freight's live pricing engine. Provide dimensions when known: for light bulky cargo volumetric weight governs the price. After this returns, an async agent double-checks the shipment; call check_offer_status with the quote_id to pick up its verdict, extra questions, or a needs_review flag.
    check_offer_statusPoll a generated offer until the async agent check settles. Returns settled (true once the check finished), possibly updated options and summary text, follow-up questions whose answers change the price or customs channel, and needs_review. If needs_review is true the prices are withheld on purpose: the goods look restricted (batteries, food, chemicals) and a human must clear them first. Tell the user Plain Freight will follow up by email; do not present a number. Branded goods are never held; they are priced on the branded channel.
    track_shipmentRead the live tracking record for a booked shipment. Requires the tracking link from the booking email (https://plainfreight.com/track/<token>) or the bare token; the token is the credential, so only someone the customer shared the link with can read the record. Returns the shipment reference, the current stage on the 10-stage lifecycle (Booking through Delivered), shipment details, and the dated event log. Read-only: to change a booking or ask a question, email hello@plainfreight.com and include the shipment reference.
