What begin_task_run_transaction does on Todos
AI agents invoke begin_task_run_transaction to trigger actions in Todos. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why begin_task_run_transaction is rated High
The tool can 'apply' a transaction (not just preview), which triggers an external operation or state change in a task management system. 'Transaction' and 'apply' indicate execution of state-changing logic. It is not purely destructive or financial, but it executes a run transaction that modifies system state.

The rule that runs begin_task_run_transaction 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 begin_task_run_transaction, this is the rule to start with:
begin_task_run_transaction stays usable, but rate-capped: a runaway agent can't fire it dozens of times 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 begin_task_run_transaction call is checked against it from then on.
