MCP exploitation attacks target the Model Context Protocol — the emerging standard for connecting AI agents to external tools. These tests cover command injection through tool parameters, data exfiltration via side channels, rug pull attacks where trusted tools change behavior, and tool description poisoning. As MCP adoption grows, so does the attack surface.

Summary
