# Connect Claude, ChatGPT or Cursor to OnlyStack (MCP)

> Let your own AI app read your OnlyFans agency's fans, chats, earnings and creators through the OnlyStack MCP server. Read only, OAuth sign-in, no API key.

OnlyStack has a **Model Context Protocol (MCP) server**, so the AI app you already use can answer questions from your agency's data: which big spenders are waiting for a reply, what each creator earned this month, which workflows sent the most messages. MCP is the standard way AI apps connect to other software.

| Server address | `https://mcp.onlystack.com/mcp` |
| Transport | Streamable HTTP |
| Sign-in | OAuth 2.0 with your OnlyStack login. No API key |
| Access | Read only. It cannot send messages, post or change anything |
| Plan | Pro and Agency |

## Connect your AI app

It takes a couple of minutes.

1. In your AI app, add a new connector (it may be called a custom connector or an MCP server) and paste `https://mcp.onlystack.com/mcp`.
2. Your AI app opens app.onlystack.com. Sign in, check what it will be able to read, and press **Allow**.
3. Ask about your fans, chats or earnings. The AI reads what it needs from OnlyStack.

### Claude Code

```bash theme={null}
claude mcp add --transport http onlystack https://mcp.onlystack.com/mcp
```

### Cursor

Add this to `~/.cursor/mcp.json`:

```json theme={null}
{
  "mcpServers": {
    "onlystack": {
      "url": "https://mcp.onlystack.com/mcp"
    }
  }
}
```

### VS Code

Add this to `.vscode/mcp.json`:

```json theme={null}
{
  "servers": {
    "onlystack": {
      "type": "http",
      "url": "https://mcp.onlystack.com/mcp"
    }
  }
}
```

### Claude and ChatGPT

Add a custom connector in the app's settings and paste the server address. ChatGPT may ask you to turn on developer mode before it accepts a custom MCP server.

## What your AI app can read

* Your connected OnlyFans accounts: chats, subscribers, earnings, posts and statistics (143 kinds of OnlyFans data)
* Your creators, team and Planner tasks
* Your workflows, their steps and recent runs, and how many messages they sent in the last 24 hours

For AI apps that limit how many tools they load, two extra tools, `find_of_endpoints` and `call_of_endpoint`, give access to the same data.

## What it can't do

These limits are built into the server and can't be turned off.

* **No writing.** There are no tools for sending messages, posting or changing settings.
* **Only what you can see.** It reads only the creator accounts that the person who connected it can open. Only owners and managers can read workflows.
* **Your plan is checked on every request.** If your agency leaves Pro, the connection stops working.
* **Disconnecting is immediate.** Remove an app in **Settings → Connections** and its next request is refused. You can also see when each app last used your data.

## Example questions

* "Which fans who spent over \$200 are still waiting for a reply?"
* "How much did each creator earn this month compared with last month?"
* "Which of my workflows sent the most messages yesterday?"
