Important: Use a plain text editor, NOT Word or Google Docs

Step 3: Add Your MCP Admin Connector

Edit the file with this basic configuration:

{
  "mcpServers": {
    "mcp-admin": {
      "command": "npx",
      "args": [
        "@mcpadmin/client",
        "--server-url",
        "https://your-mcp-admin-instance.com",
        "--api-key",
        "your-api-key-here"
      ]
    }
  }
}

Step 4: Configure with Your Details

Replace these placeholders:

• https://your-mcp-admin-instance.com → Your actual MCP Admin URL
• your-api-key-here → Your MCP Admin API key

Example (Real Setup):

{
  "mcpServers": {
    "mcp-admin": {
      "command": "npx",
      "args": [
        "@mcpadmin/client",
        "--server-url",
        "https://mcp.mcpadmin.cloud",
        "--api-key",
        "sk_live_abc123def456ghi789jkl"
      ]
    }
  }
}

Step 5: Save the File

• Save with UTF-8 encoding (default)
• Don’t change the filename
