modbender AURA Security Scanner
Protect your AI agent from malicious skills. Scan any OpenClaw, Claude MCP, or LangChain skill before installation.
What It Detects
- Malware Patterns - Credential theft, file exfiltration, crypto miners, backdoors
- Prompt Injection - Attempts to override system instructions or jailbreak agents
- Permission Issues - Overly broad filesystem, network, or execution permissions
- Suspicious Networks - Connections to known exfiltration domains (webhook.site, etc.)
- Obfuscated Code - Base64/hex encoded execution, dynamic eval patterns
Usage
Ask me to scan a skill before you install it:
"Scan this skill for security issues: https://github.com/user/cool-skill"
"Is this skill safe? https://github.com/example/mcp-tool"
"Check https://clawhub.xyz/skill/weather-api for malware"
