What you can do with FreightSimple in Claude and ChatGPT

For shippers and freight teams that quote, book and document shipments in FreightSimple.

Get carrier quotes for a shipment

Start quoting a shipment. Quoting takes about 30 seconds, so read the shipment until its status is Quoted.

Changes data

Book a quote

Book a quote of a quoted shipment. Booking makes a carrier pickup and commits the cost, so it needs explicit confirmation.

Changes data

Upload customs documents

Upload base64 PDF files, such as a commercial invoice, to a cross-border shipment. Each upload reaches the carrier at once.

Changes data

Check shipment status and tracking

Read one shipment by its id or tracking id, with its status, documents and tracking history.

Look up carriers and dangerous goods

List the carriers available to the company, and the dangerous goods entries for a UN number or text.

Maintain saved commodities

List the saved commodities, then create or delete one. Deleting a commodity cannot be undone.

How do I connect FreightSimple?

Before you connect

The login page asks for your FreightSimple company API key and Environment.

FreightSimple issues API keys to Premium-tier companies after account-manager approval. Keep the key secret. Demo keys only work with the demo environment; production keys only with production.

No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.

Claude Code

Run this command, then run /mcp in Claude Code to log in:

claude mcp add --transport http freightsimple https://freightsimple.usefulapi.io/mcp

Cursor

Add to Cursor or add this to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "freightsimple": {
      "url": "https://freightsimple.usefulapi.io/mcp"
    }
  }
}

VS Code

Add to VS Code or add this to .vscode/mcp.json:

{
  "servers": {
    "freightsimple": {
      "type": "http",
      "url": "https://freightsimple.usefulapi.io/mcp"
    }
  }
}

Codex

Run these commands. The second one opens the login page:

codex mcp add freightsimple --url https://freightsimple.usefulapi.io/mcp
codex mcp login freightsimple

Other clients

Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.

https://freightsimple.usefulapi.io/mcp

Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your FreightSimple company API key and Environment. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

Pricing

PlanPriceLimit
Free$050 tool calls / month
Proper user$9/mo · $90/yr10,000 tool calls / month
Pro+per user$39/mo · $390/yr100,000 tool calls / month

Each paid plan covers this FreightSimple server only. Ask your AI to run freightsimple_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with freightsimple_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with freightsimple_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

  • Start quotingfreightsimple_start_quoting
    Create a shipment and start the carrier quoting process (no cost is committed). Returns shipmentId and warnings. Quoting takes about 30 seconds: then poll freightsimple_get_shipment until shipmentStatus is Quoted. A cross-border shipment needs a broker.
  • Start bookingfreightsimple_start_booking
    Book a quote from a quoted shipment. This makes a carrier pickup and commits the cost, so confirm must be true. Use the quoteId from get_shipment. Poll get_shipment until shipmentStatus is BookingConfirmed (about 15 seconds).
  • Upload customs documentsfreightsimple_upload_customs_documents
    Upload customs documents (base64 PDFs, for example the commercial invoice) to a cross-border shipment. Each upload goes straight to the carrier, so confirm must be true. Use mode Replace to swap a corrected set. Upload from BookingConfirmed until delivered.

    Save a reusable commodity definition for this company.
  • Update saved commodityfreightsimple_update_saved_commodity

Your usefulapi plan · 4

  • Usage status (free-tier meter)freightsimple_usage_status
    Report the caller's current usage: the plan, calls used this month, the limit of the plan (the free monthly cap or the Pro fair use limit), remaining, and whether the limit is reached. Read-only; does not count against the meter.
  • Request a missing featurefreightsimple_request_feature
    Tell usefulapi that the user needs something the FreightSimple tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter.
  • Upgrade to Pro or Pro+freightsimple_upgrade
    Get a paid plan for FreightSimple (the free tier caps monthly usage). Pro: 10,000 tool calls a month, for normal use — plan "monthly" ($9/month) or "yearly" ($90/year, 2 months free). Pro+: 100,000 tool calls a month, for automations and heavy use — plan "plus" ($39/month) or "plus_yearly" ($390/year). Without a plan it returns both Pro and Pro+, each with a payment link, for the user to choose; with a plan, one link. An existing Pro subscription changes to Pro+ in place: call without confirm first, as the reply states the exact charge for this account (the price difference for the rest of the period, or in a free Pro trial the full Pro+ price, as the trial ends); then call with confirm: true. Cancel any time: the plan then runs to the end of the paid period, so it also suits a one-time job. A link opens Stripe Checkout in the browser; after payment the account upgrades automatically. Does not count against the meter.
  • Cancel the Pro subscriptionfreightsimple_cancel_subscription
    Cancel the caller's FreightSimple Pro subscription at the end of the paid period (no refund for the current period; Pro continues until then, then the free tier applies). Requires confirm: true. Run freightsimple_upgrade later to undo the cancel before the period ends. Does not count against the meter.

FAQ

What can I do with FreightSimple in Claude or ChatGPT?

Get carrier quotes for a shipment. Book a quote. Upload customs documents. Check shipment status and tracking. Look up carriers and dangerous goods. Maintain saved commodities. See what you can do for the details.

Is this an official FreightSimple product?

No. usefulapi is an independent service. It is not affiliated with or endorsed by FreightSimple. The server calls the FreightSimple API with your own FreightSimple access, so it sees only the data that your account can see.

Can I connect FreightSimple to Claude or ChatGPT?

Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.

What do I need to connect?

The login page asks for your FreightSimple company API key and Environment. See Before you connect for where to find them.

Do I put my FreightSimple key or an Authorization header in the client config?

No. Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your FreightSimple company API key and Environment. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

How do you keep my FreightSimple credentials?

The login stores them encrypted in the authorization grant of your connection. The server uses them to call the FreightSimple API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in FreightSimple.

Can the AI change my FreightSimple data?

Yes, if you approve it. 6 of the 12 FreightSimple tools can create or change data. The other 6 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.

What does it cost?

The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this FreightSimple server only. Cancel any time: your paid plan then runs to the end of the paid period. Run freightsimple_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run freightsimple_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run freightsimple_cancel_subscription. Your paid plan continues to the end of the paid period.

What if a FreightSimple tool that I need is missing?

Tell the AI what you wanted to do. It can send the request with freightsimple_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.

Which AI clients can I use?

Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.

This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
