WHAT IT DOES

What taskwarrior_add does on Taskwarrior MCP Server

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

WHY IT NEEDS A POLICY

Why taskwarrior_add needs a policy

This tool creates new tasks in Taskwarrior, which is a reversible write operation. It modifies the task database by adding entries but does not delete, execute arbitrary code, or move money. Severity is medium because an AI agent adding tasks maliciously could clutter the task management system or create misleading workflows, but the damage is recoverable through deletion.

From the tool's definition Tool name 'taskwarrior_add' combined with server description stating it 'allows users to list, create, modify, and organize tasks' indicates this tool creates new task entries.
