log_time · InvGate Service Desk MCP: Risk & Policy

WHAT IT DOES

What log_time does on InvGate Service Desk

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

WHY IT NEEDS A POLICY

Why log_time needs a policy

Logging time creates a new record in the system (time entry), which is a reversible write operation. It does not delete data, execute code, or move money. Misuse could result in inaccurate time tracking or billing records, hence medium severity.

From the tool's definition 'Log time on a request' — creates a time tracking entry associated with an incident/request

Verdict

log_time Rate-limited

log_time 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.
