AI agents invoke trigger_task to trigger processes or run actions in Trigger Dev. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
trigger_task can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

These attack patterns abuse exactly the kind of access trigger_task gives an agent. Each links to the full case and the policy that stops it:
Other execute tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Trigger a task run with a payload. It is categorised as a Execute tool in the Trigger Dev MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Trigger Dev MCP server in PolicyLayer and add a rule for trigger_task: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Trigger Dev. Nothing to install.
trigger_task is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the trigger_task rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for trigger_task. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
trigger_task is provided by the Trigger Dev MCP server (@triggerdotdev/trigger.dev). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
