assign_time · WorkTracker MCP Server MCP: Risk & Policy

WHAT IT DOES

What assign_time does on WorkTracker MCP Server

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

WHY IT NEEDS A POLICY

Why assign_time needs a policy

This tool creates or modifies time entries reversibly—a user can reassign or correct time allocations. It does not delete data (which would be Destructive) nor execute arbitrary code (Execute). The moderate severity reflects that misuse could incorrectly log hours, affecting payroll or billing, but changes are correctable. Medium severity is appropriate for Write operations on financial-adjacent data.

From the tool's definition Tool name 'assign_time' indicates creation or modification of time entries. Server description states the tool enables 'assign time' and 'manage daily schedules through conversational commands,' confirming it modifies time tracking data.
