## FAQ

### What does mcpg-plugin do?

It turns an already-built MCPG plugin binary into a signed, packaged, verifiable OCI artifact that a gateway or the Kubernetes operator can pull and load.

### How can I sign plugins using an external KMS or HSM?

You can use the sign --subprocess command to delegate signing to an external tool, which will receive the artifact path via the MCPG_SIGN_ARTIFACT environment variable.

### How does the tool handle registry authentication?

It resolves credentials using provided username/password flags, an explicit Docker config path, the default ~/.docker/config.json, or anonymous access.
