Risk Summary

Safe With Normal Controls

Dep Visibility is the main signal, but overall risk remains within an acceptable range.

Potential impact: This finding indicates the tool should be reviewed before it is trusted.

Recommended action: No high-risk findings were detected in this scan, but you should still apply least-privilege defaults and rescan after changes.

Suggested policy: keep this tool behind manual approval, do not allow unattended runs, and re-scan after narrowing risky permissions.

    WEATHERMAP_WEATHER

    Fix: The set of tools exposed by this server changed between scans of the same version — a sign the package was silently updated without a version bump. Audit the changelog and all tool definitions before trusting this server. Pin to a specific commit hash rather than a floating version tag.

  • InfoAS-014

    ℹ️Dependency Inventory Unavailable ×8

    Tool did not expose metadata.dependencies or repo_url, so supply-chain coverage is limited.

    Fix: Review and remediate the identified issue.

Scan this tool yourself

$ curl -sfL https://raw.githubusercontent.com/AgentSafe-AI/tooltrust-scanner/main/install.sh | bash
$ tooltrust-scanner scan --server "npx -y weather-mcp-server"

Adjust the package name if your npm registry name differs from the tool ID. View source
