Is there a way to retrieve secrets (i.e. GitHub PAT etc.pp.) from environment variables to configure MCP servers?

Hi there,

I have some custom MCP servers (http) that require authentication… the same as the marketplace servers, like GitHub (PAT). It would be nice to inject them via environment variables instead of saving them raw into the mcp_config.json.

I usually manage them via 1Password and use the CLI to inject them via secret references for extra security. I got that working easily for gemnini-cli, but not in Antigravity… it seems variable expansion is not supported for mcp server configs?

Thanks in advance for the info and consideration (if it becomes a feature request),
Adrian
