Security Findings (8)

• HighExcessive Permission Surface ×2

  • execute_query:tool declares network permission
  • execute_query:tool declares exec 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 ×5

  • execute_query:tool declares db permission
  • list_databases:tool declares db permission
  • list_tables:tool declares db permission
  • list_columns:tool declares db permission
  • switch_database_connection:tool declares db 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

  execute_query: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.
