AI agents call list_cases_for_client to retrieve information from Mycase without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries existing case data without any side effects. It performs a read-only operation that returns information associated with a client's cases. There is no creation, modification, deletion, or execution of external operations involved.
From the tool's definition Tool name 'list_cases_for_client' and description 'List all cases associated with a client' indicate a query/retrieval operation with no modification or deletion of data.

list_cases_for_client is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_cases_for_client 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 list_cases_for_client. 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.
