updateTask · Tweek MCP Server MCP: Risk & Policy

WHAT IT DOES

What updateTask does on Tweek MCP Server

AI agents use updateTask 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 updateTask needs a policy

updateTask modifies task data but does not delete or irreversibly destroy information. The operation is reversible through subsequent updates or by reverting to a previous state. It affects user task management but has limited blast radius compared to destructive operations. Severity is medium because misuse could alter user task data, impacting workflow, but changes are not permanent and can be corrected.

From the tool's definition Tool name 'updateTask' and description 'Update an existing task' indicate modification of existing data. Server description confirms 'full task CRUD operations' where Update is the reversible write operation.

Verdict

updateTask Rate-limited

updateTask 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.
