AI agents call get_usdd_mining_config to retrieve information from Justlend without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves mining configuration information from the JustLend DAO system. It performs a read-only query of existing data without creating, modifying, deleting, or executing any transactional operations. Even in the context of a DeFi protocol, a configuration getter poses minimal risk—it cannot trigger trades, transfers, or irreversible actions.
From the tool's definition Tool name 'get_usdd_mining_config' and description 'Get USDD mining configuration' indicate a retrieval operation with no side effects.

get_usdd_mining_config 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 get_usdd_mining_config 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.
