How do I install the image gen mcp server?

This profile does not contain a verified copy-paste launch configuration. Follow the current project documentation to confirm the runtime, entry point, transport and authentication before registering it in your client.

What credentials does it need?

It reads `SD_WEBUI_URL`, `SD_AUTH_USER`, `SD_AUTH_PASS`, `SD_OUTPUT_DIR`, `SD_RESIZE_MODE`, `SD_UPSCALE_MULTIPLIER`, `SD_UPSCALE_WIDTH`, `SD_UPSCALE_HEIGHT` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.
