update_ssid · API-Central MCP: Risk & Policy

WHAT IT DOES

What update_ssid does on API-Central

AI agents use update_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 update_ssid needs a policy

This tool creates or modifies SSID configuration data, which falls under the Write category. Severity is high because SSIDs control network access and authentication—modification could disable networks, change security policies, or redirect users to rogue access points, creating significant operational and security impact.

From the tool's definition Tool description states 'PATCH an existing SSID — only provided fields change', indicating modification of network configuration data. The PATCH verb and 'update' action name confirm write semantics that alter existing SSID settings.
