What create_service does on Coolify MCP Tools

AI agents use create_service to create or update resources in Coolify MCP Tools — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Coolify MCP Tools environment.

WHY IT NEEDS A POLICY

Why create_service needs a policy

This tool creates new service instances in the Coolify infrastructure, which is a reversible data/state modification operation (Write category). Severity is high because service provisioning can consume resources, affect system configuration, and create new attack surfaces, but it is not destructive (reversible), not directly executing arbitrary commands (Execute would require code injection via service args), and…

From the tool's definition Creates a one-click service instance (e.g., penpot, n8n, wordpress), which is a provisioning/deployment action that modifies infrastructure state by instantiating new services.
