Jenkins — 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.

"Tools were statically extracted from the published source (29 recovered), not enumerated from a running server.

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