With tens of thousands of Model Context Protocol (MCP) servers published in 2026, AI agents now have direct execution bridges to local terminals, filesystems, and production databases.
Following 30+ CVE disclosures against MCP tools in early 2026 alone (including CVSS 9.4+ RCEs), verifying the security of MCP servers before plugging them into Claude Desktop, Cursor, or autonomous agent runtimes has become critical.
However, existing scanning approaches suffer from two fatal flaws:
Active RCE on the Scanning Machine: Several popular scanners attempt to execute stdio commands directly from target configuration files to retrieve tool descriptions. If you scan an untrusted third-party server, you are executing arbitrary remote code on your own machine.
False-Positive Floods: Naive YARA or regex scanners trigger up to ~78% false-positive rates by flagging mock keys and test fixtures inside test/ folders.
