createTask · Tweek MCP Server MCP: Risk & Policy

WHAT IT DOES

What createTask does on Tweek MCP Server

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

WHY IT NEEDS A POLICY

Why createTask needs a policy

Creating a task is a Write operation—it creates new data but is reversible through update or delete operations. The blast radius is low since task creation does not delete data, execute code, move money, or cause irreversible harm. Tasks can be modified or removed if created in error.

From the tool's definition Tool name is 'createTask' and description states 'Create a new task'. The server description explicitly mentions 'full task CRUD operations', confirming this is a Create operation that adds new data reversibly.

Verdict

createTask Rate-limited

createTask 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.
