# Overview

> Connect Claude, Cursor, or ChatGPT to Keystone for read-only access to your wholesale data.

<Note>
  **Who this is for:** Brand users and sales reps on **Pro** or **Enterprise**. Buyer (account) users cannot connect. A brand administrator must enable MCP in Platform Settings first.
</Note>

**Keystone MCP** lets AI clients — Claude, Cursor, ChatGPT, and other [Model Context Protocol](https://modelcontextprotocol.io) clients — ask questions about your live Keystone data using the **same read-only tools** as the in-app [AI Assistant (Gus)](/features/ai-assistant).

MCP is a **Pro / Enterprise** upgrade from Basic (Basic keeps Gus in-app).

## Connect URL

```text theme={null}
https://mcp.keystoneb2b.io/mcp
```

Full setup steps for each tool: **[Connecting clients](/mcp/connecting-clients)**.\
In the app: **Settings → MCP connections** (copy URL + link to this guide).

What that means in practice:

* The AI can look up orders, invoices, shipments, accounts, products, restock timelines, and sales rankings.
* It **cannot** place orders, send emails, edit catalogs, or change settings.
* It only sees what **your Keystone role** already allows (reps see their book of business; brand users see brand-wide data).

## Before you connect

1. Confirm your brand is on **Pro** or **Enterprise** (Basic cannot connect MCP clients).
2. Ask a brand **Administrator** to turn on **Enable MCP (AI clients)** under [Settings → Platform Settings](/settings/platform-settings).
3. Be ready to sign in to the **Keystone app** (same login as day-to-day use, including SSO / MFA when enabled) — the first connection opens Keystone consent, not a separate MCP password form.
4. Follow [Connecting clients](/mcp/connecting-clients) for Claude, Cursor, or ChatGPT (remote OAuth / authorization-code + PKCE).

## What you can ask

Same kinds of questions you'd ask Gus:

> "Which of my accounts haven't ordered in the last 90 days?"

> "Show open orders for Acme Retail."

> "How much ATS do I have on SKU CC26-BLK?"

> "Top SKUs this month by invoiced quantity."
