Install a client
Any tool that speaks MCP over HTTP and lets you set a request header can connect. Three are documented here because they are the three the app generates a ready-made snippet for.
Pick your client
| Client | How it connects | Needs Node.js |
|---|---|---|
| Claude Code | One terminal command | No |
| Cursor | A .cursor/mcp.json file | No |
| Claude Desktop | Config file, through a bridge | Yes |
| Other clients | Manually, if it supports headers | Depends |
ChatGPT and claude.ai in the browser cannot connect yet. Both accept a custom MCP server only through a sign-in flow, with no field for a key. There is nowhere to put the credential this server uses.
Before you start
Two things, both from the app:
- The Server address, from Settings → Connect to AI
- A key, created on the same tab and shown once — see Authentication
The store also has to be on a paid subscription; the Connect to AI tab is not shown otherwise.
Rename the server if you have more than one store
Every snippet names the server aov-cart-drawer.
AI clients key their server list by name. Paste two stores' snippets unchanged and the second
silently replaces the first — you end up with one connection, and no way to tell from an answer
which store it came from. Give each store its own name before pasting, for example
aov-cart-drawer-northwind. The name is yours to choose; only the address and the key have to
match what the app gave you.
After you connect
Do not treat "no error" as proof. Check both halves:
-
The client sees the server.
/mcpin Claude Code, Settings → MCP in Cursor, the tools icon in Claude Desktop. You should see the server listed with 6 tools. -
The key is accepted. Ask something only this store can answer:
Is my cart drawer working right now?
A real answer means the whole chain works. A refusal means the server was reached and the key was not — see Troubleshooting.
Changing the address or the key
Remove the server and add it again rather than editing the entry in place. Clients cache what they learned when a server was first registered, and editing a URL does not always clear it.
