Unable to connect claude desktop to Marketo engage

Hi Team,

I am unable to connect Claude to Marketo MCP server.

This command didn’t work, the error I get is can’t connect to MCP server.

{
  "mcpServers": {
    "marketo": {
      "type": "http",
      "url": "https://marketo-mcp.adobe.io/mcp",
      "headers": {
        "X-Marketo-Client-Id": "YOUR-CLIENT-ID",
        "X-Marketo-Client-Secret": "YOUR-CLIENT-SECRET",
        "X-Marketo-Munchkin-Id": "YOUR-MUNCHKIN-ID"
      }
    }
  }
}

Kindly help with the issue.

Thanks,

Deepthi.
