Claude desktop & claude.ai

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.

PrerequisitesCopy Anchor Link

• A SellerSheet account with a connected store — Connect your store.
• 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 URLCopy Anchor Link

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 ClaudeCopy Anchor Link

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:

   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 testCopy Anchor Link

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 myStore-US, with your plan and each store's status. Every session should start there.

TroubleshootingCopy Anchor Link

"Unauthorized" (401)Copy Anchor Link

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 connectorCopy Anchor Link

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 opensCopy Anchor Link

Update the client — older versions don't support MCP sign-in — or use an API key.

"No stores"Copy Anchor Link

Connect a store first: Connect your store.
