Cursor

Prerequisites

Cursor installed
A MCPCore server with at least one tool
The config snippet from your server’s Integration tab

Step 1: Get your config snippet

Open your server’s detail page, click the Integration tab, and select Cursor. Copy the generated snippet. Cursor supports native HTTP transport, no npx bridge needed:

{
  "mcpServers": {
    "your-server-code": {
      "url": "https://your-subdomain.mcpcore.io/mcp"
    }
  }
}

For API Key mode:

{
  "mcpServers": {
    "your-server-code": {
      "url": "https://your-subdomain.mcpcore.io/mcp",
      "headers": {
        "X-API-Key": "<your-api-key>"
      }
    }
  }
}

For Bearer Token mode:

{
  "mcpServers": {
    "your-server-code": {
      "url": "https://your-subdomain.mcpcore.io/mcp",
      "headers": {
        "Authorization": "Bearer <your-jwt>"
      }
    }
  }
}

Step 2: Open the MCP config file

Cursor’s MCP config is at: macOS / Linux:

~/.cursor/mcp.json

Windows:

%USERPROFILE%\.cursor\mcp.json

Create the file if it doesn’t exist.

Step 3: Merge the snippet

Add your server entry to the mcpServers object. If the file is new:

{
  "mcpServers": {
    "your-server-code": {
      "url": "https://your-subdomain.mcpcore.io/mcp",
      "headers": {
        "X-API-Key": "<your-api-key>"
      }
    }
  }
}

Step 4: Reload MCP in Cursor

Save the file. You can reload without restarting Cursor: open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for MCP: Reload.

Step 5: Verify

Open Cursor’s Agent mode or a chat and ask it to use one of your tools. Your MCPCore tools are available in any AI feature.
