create_subtask · Freelo MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_subtask does on Freelo MCP Server

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

WHY IT NEEDS A POLICY

Why create_subtask needs a policy

The tool creates new subtask entities within a project management system, which is a reversible write operation. Without explicit description, severity is assessed as medium because subtask creation in a project management context has moderate blast radius—an agent could create numerous spurious subtasks cluttering projects, but the operation is reversible (sister tool 'delete_task' exists).

From the tool's definition Tool name is 'create_subtask' which indicates data creation. The server context shows this is part of Freelo project management with related tools like 'create_task', 'create_project', 'create_comment' that are all Write operations.
