Judgment Pack

Overview

Judgment Pack is a Model Context Protocol (MCP) server: Offline JPS validator, conformance tester, and experimental evaluator over stdio MCP; keyless. In practice that means any MCP-compatible AI assistant can call Judgment Pack's tools directly — the model decides when to use them in a conversation or agent run.

It runs locally: the Docker image ghcr.io/judgment-pack/judgment-pack:0.19.0 speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v0.19.0, published under the Apache-2.0 license, with source at Judgment-Pack/judgment-pack-runtime on GitHub.

Judgment Pack is listed under Development on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
