ChatGPT macOS App MCP server

The MCP Server for ChatGPT macOS App allows you to connect your ChatGPT desktop application to various MCP clients like Cursor and Chatwise. This integration enables you to use ChatGPT's capabilities within supported tools through a standardized Model Context Protocol interface.

Prerequisites

Before installing the MCP server, you'll need:

• ChatGPT macOS app installed on your system
• uv package manager installed on your system

Required Permissions

To use the MCP server properly, you need to grant accessibility permissions:

1. Open System Settings > Privacy & Security > Accessibility
2. Click the "+" button and add your MCP client (Cursor, Chatwise, etc.)
3. Ensure the checkbox next to your MCP client app is checked

Installation

The MCP server can be installed and run using the uv package manager:

uvx mcp-server-chatgpt-app

Configuration

Using with Cursor

To configure the MCP server with Cursor:

1. Update your .mcp.json file to include the following configuration:

{
    "mcpServers": {
      "chatgpt": {
        "command": "uvx",
        "args": ["mcp-server-chatgpt-app"],
        "env": {},
        "disabled": false,
        "autoApprove": []
      }
    }
}

Using with Chatwise

To configure the MCP server with Chatwise:

1. Go to Settings → Tools → Add
2. Use the following configuration:
   • Type: stdio
   • ID: ChatGPT
   • Command: uvx mcp-server-chatgpt-app

Running the Server

Once configured with your client application, the server will start automatically when needed. The MCP server creates a connection between your ChatGPT macOS app and your client application, allowing them to communicate through the Model Context Protocol.

How to add this MCP server to Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > MCP and click "Add new global MCP server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
