build_overlay_ssid · API-Central MCP: Risk & Policy

WHAT IT DOES

What build_overlay_ssid does on API-Central

AI agents use build_overlay_ssid to create or update resources in API-Central — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your API-Central environment.

WHY IT NEEDS A POLICY

Why build_overlay_ssid needs a policy

The name implies constructing/creating an SSID configuration (a Write operation). However, with no description available, confidence is low. SSID creation is reversible (can be deleted), so Write is most appropriate. Severity is medium as misconfigured SSIDs could expose network segments to unauthorized access.

From the tool's definition Tool name 'build_overlay_ssid' suggests creating or configuring an overlay SSID (wireless network); description is empty and uninformative.
