ClawSec for NanoClaw

Security advisory monitoring that protects your WhatsApp bot from known vulnerabilities in skills and dependencies.

Vercel Skills Installation

Install with the Vercel Skills CLI for this harness:

npx skills add prompt-security/clawsec --skill clawsec-nanoclaw -a openclaw -y

Overview

ClawSec provides MCP tools that check installed skills against a curated feed of security advisories. It prevents installation of vulnerable skills, includes exploitability context for triage, and alerts you to issues in existing ones.

Core principle: Check before you install. Monitor what's running.

When to Use

Use ClawSec tools when:

• Installing a new skill (check safety first)
• User asks "are my skills secure?"
• Investigating suspicious behavior
• Regular security audits
• After receiving security notifications

Do NOT use for:

• Code review (use other tools)
• Performance issues (different concern)
• General debugging

MCP Tools Available

Pre-Installation Check

// Before installing any skill
const safety = await tools.clawsec_check_skill_safety({
  skillName: 'new-skill',
  skillVersion: '1.0.0'  // optional
});

if (!safety.safe) {
  // Show user the risks before proceeding
  console.warn(`Security issues: ${safety.advisories.map(a => a.id)}`);
}

Security Audit

// Check all installed skills (defaults to ~/.claude/skills in the container)
const result = await tools.clawsec_check_advisories({
  installRoot: '/home/node/.claude/skills'  // optional
});

if (result.matches.some((m) =>
  m.advisory.severity === 'critical' || m.advisory.exploitability_score === 'high'
)) {
  // Alert user immediately
  console.error('Urgent advisories found!');
}

Browse Advisories

// List advisories with filters
const advisories = await tools.clawsec_list_advisories({
  severity: 'high',               // optional
  exploitabilityScore: 'high'     // optional
});
