Dutic MCP Server

npm
v0.2.0
Published by @josetra — 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.
Servidor MCP + CLI para el aula virtual DUTIC (Moodle) de la UNSA: tareas ocultas, notas, materiales de estudio y personas.
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 − 1.8 = 98. What the published surface and source actually contain:
| Points | What was found | Category |
|---|---|---|
| −1.8 | Hardcoded JSON Web Token in server code ×2 MTC-SRC-008 | exfiltration |
2. Client adoption risk — 98 − 7 = 91. 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 |
Capability observations and info notes are shown under Findings but never scored.

Findings 5
high Shell/command execution in server code (dist/cli/auto.js)MTC-SRC-002
In the server's implementation (`dist/cli/auto.js:1`): 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: { execFile } from "node:child_process"; import { promises as dns } from "node:dns"; import { appendFile, mkdir, readFile
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.

medium Unconstrained URL/host parameter "url" on "dutic_download_file"MTC-CAP-007
Tool "dutic_download_file" takes a URL/host parameter "url" with no allowlist/pattern. An outbound-request tool with an unbounded destination enables SSRF and cloud-metadata access (e.g. 169.254.169.254).
Fix: Allowlist destinations or constrain the parameter; block private/link-local addresses server-side.

medium Unconstrained URL/host parameter "url" on "dutic_fetch_page"MTC-CAP-007
Tool "dutic_fetch_page" takes a URL/host parameter "url" with no allowlist/pattern. An outbound-request tool with an unbounded destination enables SSRF and cloud-metadata access (e.g. 169.254.169.254).
Fix: Allowlist destinations or constrain the parameter; block private/link-local addresses server-side.

low Hardcoded JSON Web Token in server code (dist/core/saasClient.js)MTC-SRC-008
A hardcoded JSON Web Token (a public-by-design (anon/publishable) key — RLS, not secrecy, protects it) appears in `dist/core/saasClient.js:13`. Verify whether this is a real credential; if so, remove and rotate it.
Evidence: JSON Web Token: eyJh…(redacted)
Fix: Remove the secret, rotate it, and load credentials from the environment or a secret store.
Location: server dist/core/saasClient.js
low Hardcoded JSON Web Token in server code (dist/core/supabase.js)MTC-SRC-008
A hardcoded JSON Web Token (a public-by-design (anon/publishable) key — RLS, not secrecy, protects it) appears in `dist/core/supabase.js:12`. Verify whether this is a real credential; if so, remove and rotate it.
Evidence: JSON Web Token: eyJh…(redacted)
Fix: Remove the secret, rotate it, and load credentials from the environment or a secret store.
Location: server dist/core/supabase.js

What this scan could not see
- Tools were statically extracted from the published source (30 recovered), not enumerated from a running server. Tool-poisoning, Unicode-smuggling, capability and toxic-flow analysis ran on this inferred surface, but a mis-parsed registration could be missed or mis-attributed, so tool-derived findings are capped below “confirmed”. To grade the real runtime surface, scan the running server: --command "npx -y <package>".
Versions 4
Scan history per published version. The engine is deterministic — the same version always yields the same score, so a changed score means the package itself changed.
| Version | Score | Findings | Engine | Scanned |

A 91/100 | 5 | 1.13.0 | 2026-09-08 |

Embed this score
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.
Verify this score yourself
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.
