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.

Security Findings (23)

  • HighAS-012

    🔄Tool Drift

    Tool set changed silently at v1.0.2: 9 tool(s) added, 6 tool(s) removed without a version bump.

    − 6 removed

    get_author_infoget_author_photoget_authors_by_nameget_book_by_idget_book_by_titleget_book_cover

    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-002

    ⚠️Excessive Permissions

    openlibrary_search_books:input schema exposes 11 properties (threshold: 10)

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

  • LowAS-011

    ℹ️Missing Rate-Limit / Timeout ×6

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

    openlibrary_search_booksopenlibrary_get_workopenlibrary_get_editionopenlibrary_search_authorsopenlibrary_get_authoropenlibrary_get_cover_url

    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-002

    ⚠️Excessive Permissions ×6

    declared capabilities: network access, database access

    openlibrary_search_books

    declared capabilities: network access

    openlibrary_get_workopenlibrary_get_editionopenlibrary_search_authorsopenlibrary_get_authoropenlibrary_get_cover_url

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

  • InfoAS-014

    ℹ️Dependency Inventory Unavailable ×9

    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

Reproduce this audit locally, integrate into CI, or let your agent audit its own tools.

Install once, then scan any MCP server:

$ curl -sfL https://raw.githubusercontent.com/AgentSafe-AI/tooltrust-scanner/main/install.sh | bash
$ tooltrust-scanner scan --server "npx -y 8ensmith-mcp-open-library"

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