MCP (Model Context Protocol) is a standard enabling AI tools to connect, maintain sessions, and share context, likened to “USB-C for AI”. However, it lacks inherent security, opening risks like command injection, tool poisoning, and silent redefinition allowing data breaches. Developers and users need to adopt measures like input validation, monitoring, and auditing tools to mitigate these vulnerabilities. Overall, while MCP is powerful, it is not secure by default, highlighting the need for improved protocols.
