AI Analysis

●●SolidShip ItSolve My Problem

Runtime syscall tracing catches behavior static analysis misses on 70 MCP servers.

Strengths

•strace + Docker isolation captures actual runtime behavior, not just source code
•Seeded credential canary detects data exfiltration attempts automatically
•Found 3 servers phoning home at startup that static scans would miss

Weaknesses

MCP sandbox isolation for agents; E2B/Modal/Docker/WASM backends already exist separately.
