> Add the SellerSheet plugin in Claude — the skills and the MCP server together — then connect it with a browser sign-in, no key to copy.



The SellerSheet plugin gives Claude the skills **and** the MCP server in one step. Add it once in claude.ai or the Claude desktop app: it's saved to your account, so Cowork and Claude Code get it too.

## Prerequisites [#prerequisites]

* A SellerSheet account with a connected store — [Connect your store](/docs/start/connect).
* A Claude account. On a Team or Enterprise plan, an Owner may need to add the connector for your organization first.

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

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

You won't paste it for the plugin: the plugin carries the server. You need it only to add the server by hand.

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

Add the GitHub repository as a marketplace, then install the plugin from it:

1. Open **Customize → Plugins**.

2. Select **Add → Add marketplace** and enter the repository:

   ```text
   sellersheetai/sellersheet-skills
   ```

3. Find **SellerSheet Skills** among the plugins, open it and select **Add**.

**By hand instead** (the server without the skills): **Customize → Connectors → Add custom connector**, name it `SellerSheet`, paste `https://sellersheetai.com/mcp` as the server URL and click **Add**.

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

1. Open the plugin's **Connectors** tab. SellerSheet shows **Not added**: add it, then select **Connect** (added by hand: select **Connect** on it under **Customize → Connectors**). Your browser opens SellerSheet; click **Allow**, 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.

### You can't add the marketplace or the connector [#you-cant-add-the-marketplace-or-the-connector]

On a Team or Enterprise plan, an Owner decides which sources members can add and adds custom connectors for the organization. Ask an Owner to add SellerSheet, then connect it with your own account.

### 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).
