AI agents invoke invoke_automation_template to trigger processes or run actions in Courier. 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.
invoke_automation_template 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 invoke_automation_template 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.
Invoke an automation run from an existing automation template. Call list_automations first to get the template_id. Example: { template_id: "auto-onboarding", recipient: "user-123", data: { plan: "pro" } }.. It is categorised as a Execute tool in the Courier MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Courier MCP server in PolicyLayer and add a rule for invoke_automation_template: 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 Courier. Nothing to install.
invoke_automation_template 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 invoke_automation_template 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 invoke_automation_template. 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.
invoke_automation_template is provided by the Courier MCP server (https://mcp.courier.com). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
