When you can't trust yourself with your code base, trust Arbiter.

An AI coding agent guardrail — a CLI hook that blocks destructive git and filesystem commands and secret file access before they execute. Supports Amp Code, Antigravity CLI, Claude Code, Codex, Copilot CLI, Cursor, Gemini CLI, Hermes Agent, Kimi Code, OpenClaw, OpenCode, and Pi.

Stop AI agents from doing things you didn't ask for.

Second-model AI auto-review for DeepSeek Harness approval requests: a read-only reviewer subagent returns structured allow/deny verdicts with reasons, fail-closed by default, fully auditable from the session log (approval/asked -> autoReview/verdict -> approval/decided).

CLI tool to block --no-verify flag in git commands. Prevents AI agents from bypassing git hooks.

Action guardrails for AI coding agents — native Claude Code enforcement, MCP integrations, and Git/CI checks.

Anti-hallucination research mode for Claude Code. Toggle on/off to enforce citation requirements and source grounding.

Cognitive browser automation that thinks like your users—and helps AI agents navigate too. Simulate real user cognition with abandonment detection, constitutional safety, chaos engineering, and UX friction discovery. Sites that pass CBrowser's cognitive t

The vendor-neutral protocol for AI agent safety & security — and the neutral benchmark that ranks the vendors.

Don't let AI destroy your hard work! HardStop is a rock-solid protection for AI-generated commands. Pre-execution safety validation for Claude Code, Claude Cowork. Catches dangerous commands before they run: whether from AI mistakes, hallucinations, prompt injection, or misunderstood instructions. Seatbelts for the agentic AI era.

🦀 Prevents outdated Rust code suggestions from AI assistants. This MCP server fetches current crate docs, uses embeddings/LLMs, and provides accurate context via a tool call.
