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 (136)

  • HighAS-002

    ⚠️Excessive Permissions ×24

    tool declares network permission

    tool declares exec permission

    modify_account_balancecarrier_askcarrier_ask_describeprovision_esim_wizardbalance_topup_form

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

  • HighAS-010

    🔑Insecure Secret Handling

    carrier_ask:input parameter "confirm_token" appears to accept a secret or credential

    Fix: Avoid accepting raw credentials as input parameters. Use secret managers (e.g. 1Password CLI, AWS Secrets Manager) and ensure credentials are never logged or stored in agent traces.

  • MediumAS-002

    ⚠️Excessive Permissions ×9

    tool declares fs permission

    list_sponsorschange_sim_statusdelete_subscriber_packagecreate_package_templatecreate_location_zonelist_network_profilespush_steering_to_subscriber

    tool declares db permission

    subscriber_usagesubscriber_network_events

    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-003

    🔀Scope Mismatch

    set_subscriber_traffic_restrictions:tool name "set_subscriber_traffic_restrictions" implies local write operation but only remote/network-class permissions were detected

    Fix: Ensure tool names, descriptions, and permission declarations are internally consistent. Use explicit naming conventions that fully reflect actual capabilities.

  • LowAS-011

    ℹ️Missing Rate-Limit / Timeout ×29

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

    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 ×65

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