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.

    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.

  • LowAS-011

    ℹī¸Missing Rate-Limit / Timeout ×16

    tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration

    list_sitesinspect_urllist_sitemapsquery_search_analyticsadd_sitedelete_sitesubmit_sitemapdelete_sitemapget_sitemapidentify_quick_winsdetect_cannibalizationdetect_content_decayrequest_indexinglist_indexed_pagescompare_performanceweekly_digest

    Fix: Declare explicit rate-limit, timeout, and retry configuration for all network and execution tools. Implement exponential back-off and surface resource state to the calling agent.

  • InfoAS-014

    ℹī¸Dependency Inventory Unavailable ×17

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

    declared capabilities: network access, filesystem access

    delete_sitesubmit_sitemapdelete_sitemapget_sitemap

    Fix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.
