Risk Summary

Needs Approval

Dep Visibility plus Excessive Permissions raises enough risk that this tool should not be auto-trusted.

Potential impact: This finding indicates the tool should be reviewed before it is trusted.

Recommended action: Keep this tool behind manual approval and avoid unattended runs until the risky capabilities are narrowed or removed.

Suggested policy: keep this tool behind manual approval, do not allow unattended runs, and re-scan after narrowing risky permissions.

Security Findings (44)

  • HighAS-002

    ⚠️Excessive Permissions ×6

    tool declares network permission

    token_flowstoken_recent_flows_summarytoken_discovery_screenergeneral_search

    tool declares exec permission

    token_pnl_leaderboardtoken_quant_scores

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

  • MediumAS-002

    ⚠️Excessive Permissions ×5

    tool declares db permission

    token_current_top_holdersaddress_related_addressesaddress_counterpartiesgeneral_search

    tool declares fs permission

    token_quant_scores

    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-002

    ⚠️Excessive Permissions ×2

    tool declares http permission

    token_current_top_holderstoken_discovery_screener

    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 ×7

    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_screenertoken_quant_scoresgeneral_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.
