What you can do with Linnworks in Claude and ChatGPT
For online sellers and warehouse teams who manage orders and stock in Linnworks.
Check the stock level and history of a SKU
Finds a product by SKU, title or barcode and shows its stock at each location, and the history of stock changes with date, new level and note.
List open orders waiting to be despatched
Lists the open orders of a fulfilment location with status, reference, source and received date, and reads full details of selected orders.
Find an order by number or channel reference
Finds an order, open or processed, by its Linnworks order number or by an Amazon or eBay reference, and shows its details and notes.
Search despatched orders
Searches processed orders by tracking number, customer name, email, postcode, SKU or source, optionally within a date range.
Set a product's stock level at a location
Reads the current level, then sets the stock of a product at one location to an exact quantity. The new level goes to the sales channels the item is listed on.
Changes dataRead or add notes on an order
Reads the notes on an order, internal or external, and adds a new note. External notes may be passed to the sales channel.
Changes dataHow do I connect Linnworks?
Before you connect
The login page asks for your Application Id, Application Secret and Installation token.
Create the application yourself, for free, in the Linnworks Developer Portal (developer.linnworks.com, sign in with your Linnworks account-holder email): Create application → System Integration. The Application Id and Secret are on its General page. Open the Installation URL shown there while logged in to your Linnworks account and install it: the page then shows the token. Give the application only the permissions you want an AI assistant to have. These values are used only to call the Linnworks API on your behalf and are never shown to anyone.

Claude Code
Run this command, then run /mcp in Claude Code to log in:
Cursor
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"linnworks": {
"url": "https://linnworks.usefulapi.io/mcp"
}
}
} VS Code
Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"linnworks": {
"type": "http",
"url": "https://linnworks.usefulapi.io/mcp"
}
}
} Codex
Run these commands. The second one opens the login page:
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.
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 Application Id, Application Secret and Installation token. 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
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper Linnworks app installation | $9/mo · $90/yr | 10,000 tool calls / month |
| Pro+per Linnworks app installation | $39/mo · $390/yr | 100,000 tool calls / month |
Each paid plan covers this Linnworks server only. Ask your AI to run linnworks_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 linnworks_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 linnworks_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

Your usefulapi plan · 4
- Usage status (free-tier meter)
linnworks_usage_statusReport 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 feature
linnworks_request_featureTell usefulapi that the user needs something the Linnworks 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+
linnworks_upgradeGet a paid plan for Linnworks (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 subscription
linnworks_cancel_subscriptionCancel the caller's Linnworks 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 linnworks_upgrade later to undo the cancel before the period ends. Does not count against the meter.
FAQ
What can I do with Linnworks in Claude or ChatGPT?
Check the stock level and history of a SKU. List open orders waiting to be despatched. Find an order by number or channel reference. Search despatched orders. Set a product's stock level at a location. Read or add notes on an order. See what you can do for the details.
Is this an official Linnworks product?
No. usefulapi is an independent service. It is not affiliated with or endorsed by Linnworks. The server calls the Linnworks API with your own Linnworks access, so it sees only the data that your account can see.
Can I connect Linnworks 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 Application Id, Application Secret and Installation token. See Before you connect for where to find them.
Do I put my Linnworks 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 Application Id, Application Secret and Installation token. 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 Linnworks credentials?
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Linnworks 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 Linnworks.
Can the AI change my Linnworks data?
Yes, if you approve it. 2 of the 17 Linnworks tools can create or change data. The other 15 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 Linnworks server only. Cancel any time: your paid plan then runs to the end of the paid period. Run linnworks_usage_status to see how many calls you used.
How do I subscribe or cancel?
Ask the AI to run linnworks_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 linnworks_cancel_subscription. Your paid plan continues to the end of the paid period.
What if a Linnworks tool that I need is missing?
Tell the AI what you wanted to do. It can send the request with linnworks_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.
