logic-registry

logic-registry is an MCP server for Claude Code, Codex, Cursor, Gemini CLI, OpenCode from NewJerseyStyle/plugin-logic-llm. Its token cost is not measured, scanned A, original, MIT.

A local MCP server that manages a registry of logic predicates, which are named statements used in rule-based reasoning. It runs from a Node.js package and stores its registry in a configured folder.

In plain words
What is it for?
Use it as supporting infrastructure for applications or agents that manage Answer Set Programming or other rule-based logic.
Why use it?
It gives logic-based tools a shared place to register and look up predicates.

MCP server for Claude CodeCodexCursorGemini CLIOpenCode

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Part of the logic-llm plugin — 4 skills, 1 command, 8 agents, 2 hooks, 6 MCP servers shipped together

One of 6 entries in .mcp.json — they are configured in one file and arrive together.

Security

Grade A, and why

logic-registry scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
