Model Context Protocol lets AI agents call external tools, and a malicious tool description can order the agent to exfiltrate sensitive data without breaking any rule. The same agents fall to GuardFall's shell-quoting bypass, which turns a malicious repository into a supply-chain vector. Audit agent permissions and vet every tool source.
