AgentShield

Security auditor for AI agent configurations

Scans Claude Code setups for hardcoded secrets, permission misconfigs,
hook injection, MCP server risks, and agent prompt injection vectors.
Available as CLI, GitHub Action, and GitHub App integration.

Why

The AI agent ecosystem is growing faster than its security tooling. In January 2026 alone:

• 12% of a major agent skill marketplace was malicious (341 of 2,857 community skills)
• A CVSS 8.8 CVE exposed 17,500+ internet-facing instances to one-click RCE
• The Moltbook breach compromised 1.5M API tokens across 770,000 agents

Developers install community skills, connect MCP servers, and configure hooks without any automated way to audit the security of their setup. AgentShield scans your .claude/ directory and flags vulnerabilities before they become exploits.

Built at the Claude Code Hackathon (Cerebral Valley x Anthropic, Feb 2026). Part of the Everything Claude Code ecosystem (42K+ stars).

Quick Start

# Scan your Claude Code config (no install required)
npx ecc-agentshield scan

# Or install globally
npm install -g ecc-agentshield
agentshield scan

That's it. AgentShield auto-discovers your ~/.claude/ directory, scans all config files, and prints a graded security report.

Discovery intentionally skips common generated directories such as node_modules, build output, and .dmux worktree mirrors so transient copies do not duplicate findings.

    Evidence: sk-ant-a...cdef
    Fix: Replace with environment variable reference [auto-fixable]

  ● CRITICAL  Overly permissive allow rule: Bash(*)
    settings.json
    Evidence: Bash(*)
    Fix: Restrict to specific commands: Bash(git *), Bash(npm *), Bash(node *)
