start_time_tracking · Amazing Marvin MCP: Risk & Policy

WHAT IT DOES

What start_time_tracking does on Amazing Marvin MCP

AI agents invoke start_time_tracking to trigger actions in Amazing Marvin MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why start_time_tracking needs a policy

This tool executes an operation that initiates a process (time tracking) with side effects determined by its arguments. It is not merely reading data (Read), nor is it creating/modifying task data reversibly in a way that constitutes the primary function (Write). Instead, it triggers an external operation whose outcome depends on what task is specified, fitting the Execute category.

From the tool's definition start_time_tracking performs an action ('start') on a specific task that triggers an external operation (time tracking), whose effects depend on the argument (which task to track)
