Codeguard (npm) MCP Server
codeguard-mcp
npm
v1.0.1
Published by an unidentified publisher — no publish provenance and no public repository, so the publisher could not be verified and the source cannot be independently located.
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 − 25.3 = 75. What the published surface and source actually contain:
| Points | What was found | Category |
|---|---|---|
| −22 | Hardcoded AWS access key id in server code MTC-SRC-008 | exfiltration |
| −2.1 | Package has no source repository MTC-SUP-011 | supply-chain |
| −1.2 | Excessive ALL-CAPS emphasis in metadata MTC-INJ-CAPS | injection |
2. Client adoption risk — 75 − 11 = 64. 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 |
| −5 | publisher verification (unlocatable) — no provenance and no public repository to inspect |
| ✓ | inspection depth (source) — how much of the target the scan could see |
Grade capped: 1 confirmed high finding → grade capped at C. A hard gate overrides the point total — no amount of clean surface buys back a confirmed catastrophe.

Findings 12
high Hardcoded AWS access key id in server code (examples/test-code.js)MTC-SRC-008
A live-looking AWS access key id is hardcoded in `examples/test-code.js:18`. Secrets in source ship to everyone who installs the package and are a direct credential leak.
Evidence: AWS access key id: AKIA…(redacted)
Fix: Remove the secret, rotate it, and load credentials from the environment or a secret store.

high Dynamic code execution in server code (dist/scanners/vulnerability-scanner.js)MTC-SRC-001
In the server's implementation (`dist/scanners/vulnerability-scanner.js:86`): Evaluating strings as code is the most direct RCE primitive; if any tool input reaches it, the server executes attacker-chosen code. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.
Evidence: eval(
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.

high Dynamic code execution in server code (dist/utils/security-scorer.js)MTC-SRC-001

high Shell/command execution in server code (dist/scanners/vulnerability-scanner.js)MTC-SRC-002
In the server's implementation (`dist/scanners/vulnerability-scanner.js:52`): 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: exec(

low Excessive ALL-CAPS emphasis in metadataMTC-INJ-CAPS
A run of shouted words is a common way to give injected instructions false authority.
Evidence: Check code for regulatory compliance (GDPR, HIPAA, SOC2, PCI DSS)
Location: tool checkCompliance · description
low Package has no source repositoryMTC-SUP-011
"codeguard-mcp" declares no repository URL, so its published artifact cannot be compared against reviewable source.
Fix: Prefer packages that link to public, reviewable source.

What this scan could not see
- Tools were statically extracted from the published source (5 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
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 |
|---|---|---|---|---|
v1.0.1 latest |
D 64/100 | 12 | 1.7.0 | 2026-07-23 |
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.
