Judgment Pack MCP Server

judgment-pack is the vendor-neutral reference runtime for the Judgment Pack Specification (JPS). It is a reference implementation, not the only valid one: the normative specification, schemas, and conformance corpus are owned by the separate judgment-pack-spec repository, and an independent implementation is judged against the complete normative requirements of the conformance class it claims - not against this…

People who work with ai governance, conformance and json schema and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Go.
