Loading the registry…
We found this by crawling public sources and nobody has attested to it. That is how most of the registry gets here, and it is not a mark against the artifact — it only means no authenticated act of publication is on record. An artifact can be the vendor's own and still appear here.
Choose your runtime: the CLI writes the mcpServers config entry for that target.
nerlo install --target claude-code -- echo-mcp
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
8 of 11 scanners examined this package. The rest do not apply to it — language, ecosystem and packaging decide which analyzers can say anything, and a scanner that cannot examine an artifact reports nothing rather than passing it.

Findings in files this artifact installs stand as reported; a model re-read the rest and said which ones it believes are false positives. This is a second opinion published beside the evidence, not a correction to it: the per-scanner reports above are unchanged, every dismissed finding is still listed there at its original severity, and the score and the Caution badge are computed from those raw severities alone. Nothing below moved them.
Out of 100 findings across every scanner that examined this package.
Two keys had to turn. The model had to name a reason from a fixed list of six, and a deterministic check of ours — over which files this artifact actually installs — had to independently agree. Anything it could not corroborate is in “not reviewed” above, at full severity.
20 Documentation or example — The match is in documentation or sample code, confirmed by our own check to be outside the installed artifact.
Rules: opt.nerlo-rules.nerlo-install-run-bundled-artifact, MANIFEST_MISSING_LICENSE, SOCIAL_ENG_VAGUE_DESCRIPTION and 1 more · Files: /repo/.github/prompts/speckit.analyze.prompt.md, /repo/.github/prompts/speckit.checklist.prompt.md, /repo/.github/prompts/speckit.clarify.prompt.md and 10 more · reported by nerlo-install-instruction, cisco-skill-scanner
2 Agent instruction file — The match is in a file that instructs an AI coding agent — a CLAUDE.md or similar. It is documentation of intent, and our own check confirmed it is not part of what gets installed.
Rules: AAK-AGENT-005 · Files: .github/copilot-instructions.md · reported by agent-audit-kit
These findings are in files this artifact installs and are not placeholder values. No false-positive basis can be corroborated for such a finding, so this review never dismisses one; they were not sent to the model and stand at their scanner's severity.

Artifact contains hidden data files and numerous informational vulnerabilities
The artifact includes 12 instances of hidden data files, which could potentially conceal sensitive information or unexpected functionality. Additionally, 78 informational findings from various scanners indicate potential areas for review, including numerous Go vulnerabilities. These findings do not suggest immediate critical risks but warrant attention for best practices and future security posture.
Concern level assessed by the review: Low. This is the review's scale, not the registry badge.
Reviewed by gemini-2.5-flash. The model sees the findings, not your code, and cannot change a score.
