Add this server

The publisher's own command. Not a PlugMCP endpoint.

Local command

docker run -i --rm ghcr.io/judgment-pack/judgment-pack:0.32.0

Credentials from the publisher

JPACK_CONFIG — Path to a jpack.json project configuration (ADR-0012). Optional: without it the server reads jpack.json from its launch directory (/project in this image; mount a project there), and a project that does not use the convention still validates and evaluates pack documents passed over the wire.
