WHAT IT DOES

What sync_database_env_to_app does on PlugLayer MCP Server

AI agents invoke sync_database_env_to_app to trigger actions in PlugLayer MCP Server. 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 sync_database_env_to_app needs a policy

This tool executes infrastructure modifications (env var updates + app restart) whose effects depend on arguments (which app, which database). While it modifies data (env vars), the critical aspect is the restart action—an operational trigger that constitutes code/service execution in the Execute category.

From the tool's definition Tool performs 'Update one deployed app's env vars...then restart the existing app'—updates environment variables and triggers an app restart, which are operations with side effects that alter running infrastructure state.
