List supported dataset formats and installed library versions.
AI agents call list_supported_formats to retrieve information from Metis Public Health without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns information about supported formats and library versions—a straightforward read operation. It has no destructive, modifying, or executory effects. The blast radius of misuse is minimal; an AI agent learning about supported formats cannot cause harm. Low severity is appropriate for pure information retrieval about system capabilities.
From the tool's definition Tool name 'list_supported_formats' and description 'List supported dataset formats and installed library versions' both indicate retrieval of existing configuration/system information with no modifications or side effects.

list_supported_formats 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_supported_formats 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_supported_formats. 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.
