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 (39)

  • LowAS-011

    ℹ️Missing Rate-Limit / Timeout ×6

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

    token_current_top_holderstoken_flowstoken_pnl_leaderboardtoken_recent_flows_summarytoken_discovery_screenergeneral_search

    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 ×24

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