add_task_note · TasksMultiServer MCP: Risk & Policy

WHAT IT DOES

What add_task_note does on TasksMultiServer

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

WHY IT NEEDS A POLICY

Why add_task_note needs a policy

This tool creates or modifies task metadata (notes) without deleting or executing external operations. It is clearly a Write action: it adds information to an existing task, which is reversible. Severity is medium because uncontrolled note addition could spam tasks, pollute task data, or add misleading information that affects task management workflow, but it does not delete data or execute arbitrary code.

From the tool's definition Tool name 'add_task_note' and description 'Add a general note to a task' indicate creation/modification of data. Notes are appended or created on tasks, which is a reversible write operation.
