v1.19.4
Published by consiliency — no publish provenance, so origin is unverified, but the source is public: the repository link below is self-declared yet readable, so you can inspect the code before adopting it.
The grade answers one question — how safe is this server for you to adopt — so it is computed in two auditable stages. Nothing below is an opinion or an LLM's guess; every line is a real term the deterministic engine applied, and the same input always yields the same number.
1. Threat score — 100 − 40.7 = 59. What the published surface and source actually contain:
| Points | What was found | Category |
|---|---|---|
| −40.7 | Hardcoded JSON Web Token in server code ×4 MTC-SRC-008 | exfiltration |
2. Client adoption risk — 59 − 7 = 52. Three small, subtract-only factors that reflect your risk in adopting it — a clean scan proves less on a powerful, unverified or barely-inspectable package, so the grade says so plainly:
| Points | Adoption-risk factor |
|---|---|
| −6 | capability blast radius (high) — client exposure if the model is manipulated |
| −1 | publisher verification (public source) — no provenance, but the source is public and inspectable |
| ✓ | inspection depth (source) — how much of the target the scan could see |
Grade capped: 4 confirmed high findings → grade capped at D. A hard gate overrides the point total — no amount of clean surface buys back a confirmed catastrophe.
Capability observations and info notes are shown under Findings but never scored.

A live-looking JSON Web Token is hardcoded in `tests/test_auth.py:605`. Secrets in source ship to everyone who installs the package and are a direct credential leak.
Evidence: JSON Web Token: eyJh…(redacted)
Fix: Remove the secret, rotate it, and load credentials from the environment or a secret store.
Location: server tests/test_auth.py
A live-looking JSON Web Token is hardcoded in `tests/test_cli.py:1830`. Secrets in source ship to everyone who installs the package and are a direct credential leak.
Evidence: JSON Web Token: eyJh…(redacted)
Fix: Remove the secret, rotate it, and load credentials from the environment or a secret store.
Location: server tests/test_cli.py
A live-looking JSON Web Token is hardcoded in `tests/test_policy.py:315`. Secrets in source ship to everyone who installs the package and are a direct credential leak.
Evidence: JSON Web Token: eyJh…(redacted)
Fix: Remove the secret, rotate it, and load credentials from the environment or a secret store.

A live-looking JSON Web Token is hardcoded in `tests/test_tools.py:5475`. Secrets in source ship to everyone who installs the package and are a direct credential leak.
Evidence: JSON Web Token: eyJh…(redacted)
Fix: Remove the secret, rotate it, and load credentials from the environment or a secret store.

In the server's implementation (`scripts/pipeline-bootstrap/run.mjs:18`): Spawning a shell/process is command-execution capability; with unsanitized tool input it is command injection / RCE. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.
Evidence: child_process
Fix: Review this call path: confirm it never receives unsanitized tool input, constrain it, or remove it. Treat a server whose code reaches these sinks as high-capability regardless of what its tools claim.

Tool "gateway.set_startup_policy" takes a path parameter "path" with no constraint. Without a canonicalize-and-contain check (not visible statically), this permits ../ traversal outside the intended root.
Fix: Resolve and verify the path stays within an allowed root; reject traversal sequences.

The engine is deterministic — the same version always yields the same score, so a changed score means the package itself changed.

Show this server's live Trust Score in your README, docs or website. The badge is served straight from the registry and updates automatically after every rescan — no API key needed. It links back to this page, so anyone who sees the grade can also read the findings behind it instead of taking a number on faith.
The score above is reproducible: the same package version always yields the same result. Run it locally or over the free API — no account, no LLM, fully deterministic.
