Scan MCP Servers for OWASP Vulnerabilities From Inside Claude. Here's How. Every MCP server tutorial teaches you how to build. None of them teach you how to verify it's secure before deploying. We built Cybersecify — an MCP security scanner you can run from inside your AI assistant. Claude, Cursor, Windsurf, any MCP client. One config line, then ask it to scan. No CLI. No separate tool. Just talk to your AI and it scans for you. Why this matters MCP adoption just crossed 97 million SDK downloads. There are 13,000+ servers in the wild. Most have no authentication, no signing, no input validation. We know because we scan them. CVE-2026-39313 (CVSS 8.7) was a single missing size check in a popular MCP framework. The config existed.
