AI agents call list_mailroom to retrieve information from Filevine without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves mailroom data without modifying, deleting, or executing any operations. It is a straightforward read operation typical of case management systems where viewing mailroom items (documents, correspondence) is a standard informational function. The low severity reflects minimal blast radius—listing existing items cannot cause damage, financial loss, or unintended modifications.

list_mailroom 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_mailroom 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_mailroom. 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.
