Security Findings (29)

• CriticalArbitrary Code Execution

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

  Rule: AS-006Fix: 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.
• HighExcessive Permission Surface ×5

  • GOOGLESHEETS_EXECUTE_SQL:tool declares exec permission
  • GOOGLESHEETS_QUERY_TABLE:tool declares network permission
  • GOOGLESHEETS_QUERY_TABLE:tool declares exec permission
  • GOOGLESHEETS_SEARCH_DEVELOPER_METADATA:tool declares network permission
  • GOOGLESHEETS_SEARCH_SPREADSHEETS:tool declares network permission

  Rule: AS-002Fix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.
• MediumExcessive Permission Surface ×14

  • GOOGLESHEETS_BATCH_UPDATE:tool declares fs permission
  • GOOGLESHEETS_BATCH_UPDATE_VALUES_BY_DATA_FILTER:tool declares fs permission
  • GOOGLESHEETS_CREATE_CHART:tool declares fs permission
  • GOOGLESHEETS_CREATE_GOOGLE_SHEET1:tool declares fs permission
  • GOOGLESHEETS_CREATE_SPREADSHEET_COLUMN:tool declares fs permission
  • GOOGLESHEETS_CREATE_SPREADSHEET_ROW:tool declares fs permission
  • GOOGLESHEETS_DELETE_DIMENSION:tool declares fs permission
  • GOOGLESHEETS_DELETE_SHEET:tool declares fs permission
  • GOOGLESHEETS_EXECUTE_SQL:tool declares db permission
  • GOOGLESHEETS_GET_TABLE_SCHEMA:tool declares db permission
  • GOOGLESHEETS_LOOKUP_SPREADSHEET_ROW:tool declares db permission
  • GOOGLESHEETS_QUERY_TABLE:tool declares db permission
  • GOOGLESHEETS_UPDATE_SHEET_PROPERTIES:tool declares fs permission
  • GOOGLESHEETS_UPDATE_SPREADSHEET_PROPERTIES:tool declares fs permission

  Rule: AS-002Fix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.
• LowExcessive Permission Surface ×4

  • GOOGLESHEETS_CREATE_CHART:input schema exposes 13 properties (threshold: 10)
  • GOOGLESHEETS_EXECUTE_SQL:tool declares http permission
  • GOOGLESHEETS_FORMAT_CELL:input schema exposes 15 properties (threshold: 10)
  • GOOGLESHEETS_UPSERT_ROWS:tool declares http permission

  Rule: AS-002Fix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.
• LowDoS Resilience — Missing Rate Limit / Timeout ×5

  • GOOGLESHEETS_EXECUTE_SQL:tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration
  • GOOGLESHEETS_QUERY_TABLE:tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration
  • GOOGLESHEETS_SEARCH_DEVELOPER_METADATA:tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration
  • GOOGLESHEETS_SEARCH_SPREADSHEETS:tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration
  • GOOGLESHEETS_UPSERT_ROWS:tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration

  Rule: AS-011Fix: 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.
