Loading the registry…
The publisher performed an authenticated act of publication — proving control of a namespace in the official MCP registry, or appearing in a first-party catalogue an operator curates. That establishes WHO published it. It is not a security finding, and attested artifacts carry Flagged verdicts too.
11 critical findings reported by cisco-skill-scanner, agent-audit-kit, 6 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-gateway
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
6 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 645 findings across every scanner that examined this package. 5 of 11 findings rated critical by their scanner were among the dismissals.
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.

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.

Credential harvesting, secret exposure, and dynamic execution risks identified.
Critical findings indicate potential credential harvesting in `/repo/vendor/github.com/digitorus/pkcs7/verify_test_dsa.go` and `/repo/vendor/github.com/sigstore/rekor/pkg/pki/x509/e2e.go`. High severity findings reveal exposed secrets in `pkg/gateway/auth.go`. The artifact includes hidden executable scripts in `/repo/vendor/github.com/dop251/goja/.tc39_test262_checkout.sh` and dynamic execution capabilities in `/repo/pkg/interceptors/interceptors.go`. Additionally, permissive Bash permissions for Docker commands are present in `settings.json`.
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.
