DisableProxy · Veeam VBR v13 MCP Server MCP: Risk & Policy

WHAT IT DOES

What DisableProxy does on Veeam VBR v13 MCP Server

AI agents use DisableProxy to create or update resources in Veeam VBR v13 MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Veeam VBR v13 MCP Server environment.

WHY IT NEEDS A POLICY

Why DisableProxy needs a policy

Disabling a backup proxy changes its operational state in a reversible way (it can be re-enabled), placing it in the Write category. However, the blast radius is high because disabling a proxy could interrupt ongoing backup or restore jobs, potentially causing data protection failures across the infrastructure.

From the tool's definition 'Disable a backup proxy' — disabling a proxy modifies its state but does not irreversibly delete it; it can presumably be re-enabled.
