VirusTotal catches known malware. We catch what it misses.
ClawAudit is the only security scanner built for MCP servers — the tools you connect to Claude, Claude Code, Cursor, and Windsurf.
Detect prompt injection, data exfiltration, and tool poisoning — before they reach your agent.

ClawAudit DB
VirusTotal scans files. We understand MCP.
Generic scanners don't understand MCP's unique attack surface. A malicious tool description is just text to VirusTotal — it's a full agent hijack to us.
MCP servers run with the same permissions as your AI agent. One malicious tool can read your files, exfiltrate your credentials, and manipulate every response Claude gives you.
Three layers of protection
Each layer catches what the others miss.
Static analysis
Regex + YARA-like rules match against our MCP threat signature database. Catches known patterns from ToolPoison, ExfilMCP, and AuthGrab campaigns.
All plans · <1s
AI semantic analysis
Our engine reads the MCP server like a security researcher. Detects tool poisoning hidden in descriptions, obfuscated callbacks, and context injection attacks.
Starter+ · 2-5s
MCP threat database
Curated from Invariant Labs, Snyk, Cisco AI Defense, and our own research. Updated with every new campaign. Not generic CVEs — real MCP-specific threats.
