Read Linnworks inventory, stock and orders; set stock levels and add order notes. Hosted by usefulapi — connect from Claude, ChatGPT, Cursor, or any MCP client.
Team and Enterprise: an Owner adds the connector for the organization first.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"linnworks": {
"url": "https://linnworks.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"linnworks": {
"type": "http",
"url": "https://linnworks.usefulapi.io/mcp"
}
}
}No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
Run these commands. The second one opens the login page:
Other MCP clients (Windsurf, Cline, Zed and more): add the URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser. Do not add an Authorization header: see 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.
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.
Turn on the Linnworks connector, then ask in plain words. The AI picks the tools.
| Tool | Type | What it does |
|---|---|---|
linnworks_list_stock_locations | read | List stock locations List the stock locations (warehouses, fulfilment centres) of the Linnworks account: id, name, address, whether it is a fulfilment centre. Use the ids as location_id in other tools. GET /api/Inventory/GetStockLocations. |

linnworks_request_feature | Request a missing feature Tell 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. | |
linnworks_upgrade | Upgrade to Pro (unlimited) Subscribe to the Pro plan for UNLIMITED Linnworks tool calls (the free tier caps monthly usage). Choose monthly ($9/month) or yearly ($90/year — 2 months free) billing. Returns a Stripe Checkout link to open in your browser; after payment your account upgrades automatically. Does not count against the meter. | |
linnworks_cancel_subscription | Cancel the Pro subscription Cancel the caller's Linnworks Pro subscription at the end of the paid period (no refund for the current period; unlimited calls continue 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. |
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper Linnworks app installation | $9/mo · $90/yr | Unlimited |
Pro covers this Linnworks server only. Subscribe with linnworks_upgrade (it returns a Stripe Checkout link). Cancel any time with linnworks_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running linnworks_upgrade before then undoes the cancel. Or write to [email protected].
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.
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.
The login page asks for your Application Id, Application Secret and Installation token. See Before you connect for where to find them.
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.
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.
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.
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with unlimited tool calls, for this Linnworks server only. Run linnworks_usage_status to see how many calls you used.
Ask the AI to run linnworks_upgrade: it returns a Stripe Checkout link. To cancel, run linnworks_cancel_subscription. Pro continues to the end of the paid period.
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.
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.
