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 (34)

  • HighAS-002

    ⚠️Excessive Permissions ×2

    tool declares network permission

    gs_create_spreadsheet

    tool declares exec permission

    gs_add_protected_range

    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 fs permission

    gs_create_spreadsheetgs_write_valuesgs_batch_writegs_delete_sheetgs_batch_update

    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

    gs_create_spreadsheetgs_add_protected_range

    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.

  • LowAS-002

    ⚠️Excessive Permissions ×2

    input schema exposes 23 properties (threshold: 10)

    gs_format_cells

    input schema exposes 11 properties (threshold: 10)

    gs_add_chart

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

  • InfoAS-014

    ℹ️Dependency Inventory Unavailable ×23

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