agent-security is a plugin marketplace that provides local secret-scanning hooks for Claude Code and Cursor so developers can reduce accidental credential leakage during agent sessions.
About
agent-security is a Claude Code and Cursor marketplace focused on preventing coding agents from propagating secrets during everyday work. Install it when you need editor hooks that scan prompts and file or bash tool usage for common credential formats without external dependencies. The repository ships a secrets-scanner plugin plus PyPI packages for teams that prefer manual hook wiring.
- Marketplace distributes secrets-scanner with regex-only local scanning
- Hooks cover UserPromptSubmit, PreToolUse reads, and PostToolUse read/bash
- Also installable via pipx as claude-secret-scan with manual hook config
- Cursor example hooks in examples/configs/cursor-hooks.json
