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.
4 critical findings reported by trivy, osv-scanner. The composite score alone does not reflect this — read the per-scanner reports below.
github_release: https://github.com/Moonsong-Labs/substrate-mcp, 0 findings
Choose your runtime: the CLI writes the mcpServers config entry for that target.
nerlo install --target claude-code -- substrate-mcp
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
7 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 172 findings across every scanner that examined this package. None of the 4 findings rated critical by their scanner were dismissed.
Not reviewed is not the same as clean. Those 156 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.
12 Documentation or example — The match is in documentation or sample code, confirmed by our own check to be outside the installed artifact.

Critical vulnerabilities and risky installation methods detected
Multiple critical vulnerabilities are present in dependencies listed in `/repo/evals/bun.lock`. The artifact's installation instructions in `/repo/README.md` and `/repo/install.sh` include piping raw fetched content directly to a shell, which can lead to arbitrary shell execution. Additionally, a high-severity pipeline taint flow finding in `/repo/install.sh` indicates potential for untrusted input to influence shell commands.
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.
Showing 25 of 25; the rest are in the per-scanner reports above.
