WHAT IT DOES

What approve_task does on Todos

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

RISK

Why approve_task is rated Medium

The tool modifies task records by changing their approval status and recording approval metadata. This is a Write operation—it creates or modifies data reversibly. While it affects workflow state, it does not execute arbitrary code, delete data irreversibly, or commit financial obligations.

From the tool's definition Tool description states it 'Approve a task' and 'Records who approved it', indicating a modification of task state (approval status) and metadata (approver information). This is a reversible state change, not data deletion or financial impact.

RECOMMENDED RULE

The rule that runs approve_task safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Todos, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For approve_task, this is the rule to start with:

approve_task Rate-limited

approve_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.

The button opens the PolicyLayer dashboard: create your workspace, connect Todos, apply this rule, and every approve_task call is checked against it from then on.
