WHAT IT DOES

What deployApp does on kintone OAuth MCP Server on Cloudflare Workers

AI agents invoke deployApp to trigger actions in kintone OAuth MCP Server on Cloudflare Workers. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why deployApp needs a policy

This tool executes a deployment action that modifies the live production state of a kintone app. While not technically destructive (settings can be reverted), it is an Execute-class tool because it triggers an external operation whose consequences depend on what settings are being deployed. The high severity reflects the blast radius: a misconfigured or malicious deployment could disrupt service for all app users.

From the tool's definition The tool performs 'Deploy app settings to production', which triggers an external operation (deployment) with irreversible side effects in a production environment.
