Tip: Run a Taint-Style Scanner Against Your Own MCP Servers Before You Ship Them
Adversa AI·medium signal
With VIPER-MCP demonstrating that automated taint analysis plus prompt-fuzzing can drive real exploits in ~40K MCP repos, builders shipping custom servers should treat tool inputs as untrusted sinks: scan for attacker-controlled values flowing into shell/file/DB calls, require auth on remote endpoints (≈40% don't), and keep servers sandboxed with scoped credentials. Self-scanning before publish is now table stakes, not optional hardening.
