Common questions
Is SKU.io safe?
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.0.1) reached the registry 18 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?

SKU.io MCP Server
The official Model Context Protocol server for SKU.io, the inventory and order management system for multi-channel e-commerce.
Connect an AI assistant to your SKU.io account and it can look up products, stock per warehouse, sales orders and purchase orders. If you allow it when you connect, it can also create draft sales orders and purchase orders, adjust inventory, record supplier invoices and more.
This is a hosted (remote) server. There is nothing to install or run. This repository holds its documentation and its registry entry (server.json), not its source code.
| Server URL | https://mcp.sku.io/mcp |
| Transport | Streamable HTTP |
| Authentication | OAuth 2.1 with PKCE (dynamic client registration and client ID metadata documents are both supported) |
| Registry name | io.sku/sku |
Every SKU.io account uses the same URL. You choose your account when you sign in.
Requirements
- A SKU.io account. The assistant sees only what your role can see, and changes only what your role can change.
- An admin can switch assistants off for the whole account, or limit them to looking things up, under Settings → Developer → MCP Server → Settings.
Configure
VS Code (GitHub Copilot)
Install it from the MCP server gallery (search @mcp SKU.io in the Extensions view), or add it to .vscode/mcp.json:
{"servers": { "sku": { "type": "http", "url": "https://mcp.sku.io/mcp" } } }
Start the server, and VS Code opens a browser window for you to sign in to SKU.io.
Claude, ChatGPT and Cursor
Add a custom connector with the URL https://mcp.sku.io/mcp and leave its sign-in set to OAuth. Step-by-step instructions for each app: Connect an AI assistant.
Claude Code
claude mcp add --transport http sku https://mcp.sku.io/mcpThen run /mcp in Claude Code and choose Authenticate.
Sign in and choose what the assistant may do
When your client sends you to SKU.io:
- Check that You will be sent back to names the app you started from. If it names anything else, click Cancel.
- Choose the SKU.io Account to connect, if you belong to more than one.
- View data is always on. To let the assistant create and update records, turn on Allow changes, then untick any area it should not change: Orders, Purchasing, Inventory, Products, Accounting, or Settings & automations.
- Click Approve.
What it can do
| Access | Tools |
|---|---|
| View data (always) | find_product, search_products, get_products, get_inventory_levels, get_stockout_risk, list_warehouses, get_orders, get_order_status, search_purchase_orders, get_purchase_order_details, get_send_plan, explain_send, compare_scenarios, get_reimbursement_cases, diagnose_tiktok_listing, list_support_insights_reports, get_support_insights_report, whoami |
| Orders | create_sales_order (always a draft until you approve it in SKU.io) |
| Purchasing | create_purchase_order (draft), submit_purchase_order, record_purchase_invoice |
| Inventory | adjust_inventory |
| Products | create_product, update_product_pricing |
| Accounting | record_vendor_credit (draft) |
| Settings & automations | create_saved_view, create_workflow_draft (never published) |
Four more tools reach the rest of the SKU.io REST API: search_api and describe_endpoint find and explain an endpoint, api_read calls read-only endpoints, and api_write runs a fixed set of changes SKU.io has reviewed for assistants. Each change still needs the matching Allow changes area.
Whatever you approve, an assistant can never delete or void anything, or manage users, roles, billing or tokens. Every call it makes is listed on the Activity tab under Settings → Developer → MCP Server.
Example prompts
- "How much stock of the 750 ml water bottle do we have, and is more on order?"
- "Which products will run out in the next 30 days?"
- "What's the status of order 10482?"
- "Draft a purchase order to our usual supplier for everything at risk of stocking out."
Each answer links back to the record in SKU.io.
