server_service_start · ArcGIS MCP: Risk & Policy

WHAT IT DOES

What server_service_start does on ArcGIS MCP

AI agents invoke server_service_start to trigger actions in ArcGIS MCP. 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 server_service_start needs a policy

While labeled 'write operation,' starting a service is fundamentally an Execute action—it triggers an external system operation whose consequences depend on the service argument. This differs from simple data creation (Write) because it activates infrastructure components. Misuse could disable critical geospatial services, impact dependent applications, or disrupt organizational operations, warranting high severity.

From the tool's definition Tool name 'server_service_start' explicitly starts a service on ArcGIS Server. Description confirms 'Inicia un servicio detenido' (starts a stopped service) and marks it as 'OPERACIÓN DE ESCRITURA' (write operation).
