login_agent · Oitvoip MCP: Risk & Policy

WHAT IT DOES

What login_agent does on Oitvoip

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

WHY IT NEEDS A POLICY

Why login_agent needs a policy

This tool modifies the state of an agent by logging them into a call queue. This is a reversible state change (agents can be logged out), making it a Write operation. Misuse could disrupt call routing and queue management, resulting in medium severity.

Verdict

login_agent Rate-limited

login_agent stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
