MCP Vulnerability

Model Context Protocol (MCP) vulnerability refers to security flaws or weaknesses in the open standard that enables AI applications to safely interact with external tools and data sources. These vulnerabilities can allow attackers to bypass authentication controls, inject malicious commands, or gain unauthorized access to sensitive data through compromised tool integrations. Understanding and patching MCP vulnerabilities is critical for enterprises deploying AI agents and multi-tool systems, as attackers could exploit these gaps to manipulate AI behavior or exfiltrate information.
