> Add SellerSheet to the Claude desktop app or claude.ai as a custom connector — browser sign-in, no key to copy.



Add SellerSheet to Claude as a custom connector — the same steps work in the desktop app and on claude.ai in the browser.

## Prerequisites [#prerequisites]

* A SellerSheet account with a connected store — [Connect your store](/docs/start/connect).
* A paid Claude plan — custom connectors need one.

## Step 1: Copy the SellerSheet MCP URL [#step-1-copy-the-sellersheet-mcp-url]

```text
https://sellersheetai.com/mcp
```

## Step 2: Add SellerSheet in Claude [#step-2-add-sellersheet-in-claude]

1. Open **Settings → Connectors → Add custom connector**.
2. Name it `SellerSheet` and paste `https://sellersheetai.com/mcp` as the server URL.

## Step 3: Sign in and test [#step-3-sign-in-and-test]

1. Click **Connect**. Your browser opens the SellerSheet sign-in; approve, and you're back in Claude.
2. Ask: "Which stores can you see?" Your agent calls `get_user_context` and lists your store refs, such as <StoreRef />, with your plan and each store's status. Every session should start there.

## Troubleshooting [#troubleshooting]

### "Unauthorized" (401) [#unauthorized-401]

Your sign-in or key expired or was deleted. Sign in again, or create a new key.

### The browser never opens [#the-browser-never-opens]

Update the client — older versions don't support MCP sign-in — or use an [API key](/docs/mcp-api/keys).

### "No stores" [#no-stores]

Connect a store first: [Connect your store](/docs/start/connect).
