create_task · Mycase MCP: Risk & Policy

WHAT IT DOES

What create_task does on Mycase

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

WHY IT NEEDS A POLICY

Why create_task needs a policy

This tool creates a new task record, which is reversible (tasks can be deleted or modified). It does not execute arbitrary code, delete data irreversibly, or move money. It modifies the state of the law firm's case management system by adding a task, making it a Write operation. Severity is medium because misuse could create spurious tasks that clutter workflows, but the impact is containable and reversible.

From the tool's definition Tool name 'create_task' and description 'Create a task' indicate data creation. The tool accepts parameters (priority, due_date, staff_id) that configure a new task record in the MyCase law firm management system.

Verdict

create_task Rate-limited

create_task stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
