Anthropic Releases Claude Security Plugin for Claude Code in Beta: A Multi-Agent Vulnerability Scanner That Runs in Your Terminal

MarkTechPost · 2 months ago · 44

Anthropic released Claude Security, a beta plugin for Claude Code that scans repositories for vulnerabilities using a six-phase multi-agent workflow and generates patch suggestions. The plugin uses a 3-voter adversarial panel to verify findings, with only those achieving a 2-of-3 quorum included in reports, and patches are independently verified before presentation. Users must have a paid Claude Code plan v2.1.154 or later with Python 3.9.6+ installed, and scans run locally under the user's session permissions without automatic patching.
