Scan your Claude Code configuration (.claude/ directory) for security vulnerabilities, misconfigurations, and injection risks using AgentShield. Checks CLAUDE.md, settings.json, MCP servers, hooks, and agent definitions.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# Security Scan Skill
Audit your Claude Code configuration for security issues using [AgentShield](https://github.com/affaan-m/agentshield).
## When to Activate
- Setting up a new Claude Code project
- After modifying `.claude/settings.json`, `CLAUDE.md`, or MCP configs
- Before committing configuration changes
- When onboarding to a new repository with existing Claude Code configs
- Periodic security hygiene checks
## What It Scans
| File | Checks |
|------|--------|
| `CLAUDE.md` | Hardcoded secrets, auto-run instructions, prompt injection patterns |
| `settings.json` | Overly permissive allow lists, missing deny lists, dangerous bypass flags |
| `mcp.json` | Risky MCP servers, hardcoded env secrets, npx supply chain risks |
| `hooks/` | Command injection via interpolation, data exfiltration, silent error suppression |
| `agents/*.md` | Unrestricted tool access, prompt injection surface, missing model specs |
## Prerequisites
AgentShield must be installed. Check and install if needed:
```bash
# Check if installed
npx ecc-agentshield --version
# Install globally (recommended)
npm install -g ecc-agentshield
# Or run directly via npx (no install needed)
…
The line at the top of this page pins the label git:20260702.9dc0119, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
A 17 of 17 checks passed. Fixed automatic checks with no AI involved, so the same checks give the same answer every run.
