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.
134 critical findings reported by cisco-skill-scanner, 133 of them in the installed artifact. The composite score alone does not reflect this — read the per-scanner reports below.
Choose your runtime: the CLI writes the mcpServers config entry for that target.
nerlo install --target claude-code -- mcp-server-and-client
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
4 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 Flagged badge are computed from those raw severities alone. Nothing below moved them.
Out of 1,256 findings across every scanner that examined this package. 1 of 134 findings rated critical by their scanner was among the dismissals.
Not reviewed is not the same as clean. Those 742 findings stand exactly as their scanners reported them, at full severity, as they would have without this review.
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.
7 Documentation or example — The match is in documentation or sample code, confirmed by our own check to be outside the installed artifact.

2 Test or fixture file — The match is in a test or fixture. Our own check confirmed the file is not part of what gets installed.

The model could have called any of these a false positive and did not.

Critical command injection and credential harvesting risks.
The artifact contains critical command injection vulnerabilities, including `eval` and `child_process` usage, found in multiple files such as `/repo/node_modules/@cspotcode/source-map-support/source-map-support.js` and `/repo/node_modules/@inquirer/external-editor/dist/commonjs/index.js`. It also exhibits critical credential harvesting capabilities and patterns indicative of coercive injection. High severity findings include potential DNS rebinding and hidden executable scripts. Additionally, medium severity findings point to autonomy abuse and exposed secret password variables.
Concern level assessed by the review: Critical. 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.
