Risk Summary

Needs Approval

Missing Description plus Dep Visibility 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 (11)

  • CriticalAS-006

    💻Arbitrary Code Execution

    heuristic signal

    zs_execute:tool name or description implies arbitrary script/code execution (evaluate_script, execute javascript, etc.)

    Fix: This tool can execute arbitrary code or shell commands on the host system. Remove it unless strictly required. If kept: (1) restrict access to trusted users/agents only, (2) require human approval before each invocation (Claude Desktop: set approval_required: true; other clients: enable equivalent confirmation), (3) use the most restrictive sandbox or read-only mode available, and (4) never expose this tool to untrusted input sources.

  • HighAS-002

    ⚠️Excessive Permissions ×2

    tool declares exec permission

    zs_executezs_validate

    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 ×2

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

    zs_executezs_validate

    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-007

    ℹ️Missing Description or Schema ×3

    Tool 'zs_execute' has no description - agents cannot reason about its purpose, and static analysis coverage is limited

    zs_execute

    Tool 'zs_validate' has no description - agents cannot reason about its purpose, and static analysis coverage is limited

    zs_validate

    Tool 'zs_operations' has no description - agents cannot reason about its purpose, and static analysis coverage is limited

    zs_operations

    Fix: Review and remediate the identified issue.

  • InfoAS-014

    ℹ️Dependency Inventory Unavailable ×3

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

    zs_executezs_validatezs_operations

    Fix: Review and remediate the identified issue.
