Today, mcp-xray (https://github.com/traceforce/mcp-xray) can be used to dynamically (not just statically) test against your MCPs. It can detect security vulnerabilities such as code execution, SSRF, path traversal, authorization bypass, input injection, DoS etc. You can find us at demo labs during DEF CON this year. That said, we think behavioral influence is an important problem and it's an area we're interested in exploring next.
