WHAT IT DOES

What ccx_scale_datastore does on Severalnines CCX MCP Server

AI agents invoke ccx_scale_datastore to trigger actions in Severalnines CCX 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 ccx_scale_datastore needs a policy

The tool performs infrastructure modification actions (resizing CPU/RAM, expanding storage) that have real operational effects. While reversible via scale-down operations, this is a consequential system operation that could impact availability, performance, or incur costs during execution.

From the tool's definition Scale a CCX datastore by resizing the instance (CPU/RAM) or expanding storage. This triggers external operations that modify infrastructure resources.
