WHAT IT DOES

What toggl_stop does on Toggl MCP Server

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

WHY IT NEEDS A POLICY

Why toggl_stop needs a policy

Stopping a timer modifies the state of an active time entry by ending it. This is a reversible write operation (a new timer can be started), not destructive since the recorded time data is preserved. Misuse could disrupt time tracking workflows.
