Documentation
README · ~2 min readSemgrep Guardian: Claude Code Plugin
A plugin that runs in Claude Code, detecting and resolving the vulnerabilities, malicious packages, and hardcoded secrets your agent introduces before code even gets pushed.
Semgrep Guardian integrates natively with AI coding agents like Claude Code and Cursor to catch security issues before they ship. It bundles the Semgrep MCP server, and Hooks into a single install, and scans every file an agent generates using Semgrep Code, Supply Chain, and Secrets. When findings are detected, the agent is prompted to regenerate code until Semgrep returns clean results or you choose to dismiss them.
