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 (50)

  • HighAS-012

    🔄Tool Drift

    Tool set changed silently at v0.10.1: 21 tool(s) added, 2 tool(s) removed without a version bump.

    − 2 removed

    check_creditsverify_email

    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 ×3

    input schema exposes 18 properties (threshold: 10)

    list_emails_metadata

    input schema exposes 11 properties (threshold: 10)

    send_email

    input schema exposes 12 properties (threshold: 10)

    save_to_mailbox

    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 ×10

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

    list_emails_metadataget_emails_contentlist_allowed_senderssend_emailforward_emailsave_to_mailboxsave_draftmove_emailsdownload_attachmentemail_command

    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 ×21

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

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 mcp-email-server"

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