What add_task_run_event does on Todos
AI agents use add_task_run_event 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.
Why add_task_run_event is rated Medium
This tool creates or modifies task run event records. While it records various event types (progress, comments, status changes), these are reversible operations - events can typically be edited, superseded, or their state reverted in a task management system. It does not irreversibly delete data (Destructive), execute arbitrary code (Execute), move money (Financial), or merely read data (Read).
From the tool's definition Tool description states it can 'Record a local run event' with multiple types including 'progress, comment, claim, command, file, artifact, completed, failed, or cancelled' - these are reversible modifications to task run state.
Attacks that exploit this kind of access
The rule that runs add_task_run_event 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 add_task_run_event, this is the rule to start with:
add_task_run_event 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 add_task_run_event call is checked against it from then on.
