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.

    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

    ℹ️Missing Rate-Limit / Timeout ×12

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

    Gmail_GetEmailGmail_ListEmailsGmail_ListEmailsByHeaderGmail_ReplyToEmailGmail_SearchEmailsByQueryGmail_SearchThreadsGmail_SendEmailGmail_TriageEmailsGmail_UnsubscribeFromEmailGmail_UpdateDraftEmailGmail_WriteDraftEmailGmail_WriteDraftReplyEmail

    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

    ℹ️Dependency Inventory Unavailable ×31

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

    Fix: Review and remediate the identified issue.

    ⚠️Excessive Permissions ×20

    declared capabilities: database access

    Gmail_ChangeEmailLabels

    declared capabilities: filesystem access

    Gmail_CreateLabelGmail_DeleteDraftEmailGmail_DeleteLabelGmail_ForwardEmailGmail_ListEmailAttachmentMetadataGmail_UpdateLabelGmail_WhoAmI

    declared capabilities: filesystem access, HTTP requests

    Gmail_GetEmailGmail_ReplyToEmailGmail_SendEmailGmail_UpdateDraftEmailGmail_WriteDraftEmailGmail_WriteDraftReplyEmail

    declared capabilities: HTTP requests

    Gmail_ListEmailsGmail_ListEmailsByHeader

    declared capabilities: network access, database access

    Gmail_SearchEmailsByQueryGmail_UnsubscribeFromEmail

    declared capabilities: network access, HTTP requests

    Gmail_SearchThreads

    declared capabilities: database access, HTTP requests

    Gmail_TriageEmails

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

Scan this tool yourself

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

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

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