Get app-level access permissions
AI agents call getAppAcl to retrieve information from kintone OAuth MCP Server on Cloudflare Workers without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves access control list (ACL) information from a kintone app. It performs a query operation with no capability to modify, delete, or execute code. The blast radius is low—misuse would only expose what permissions are already configured, not change system state or compromise data integrity.
From the tool's definition Tool name 'getAppAcl' and description 'Get app-level access permissions' indicate a retrieval operation without side effects.
