Malcolm — the complete, unedited output of the deterministic mcptrustchecker engine v1.13.0, scanned . Every finding, capability tag and score component below is exactly what the engine produced — no AI, no post-processing.

To grade the real runtime surface, scan the running server: --command \"npx -y <package>\"."
