AI agents call get_yields to retrieve information from MoltLlama 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 DeFi yield data from DeFiLlama without side effects. It retrieves information about yield farming opportunities to inform decision-making but does not execute trades, move funds, modify protocols, or run arbitrary code. The filtering parameters are read-only query constraints.
From the tool's definition Tool name 'get_yields' and description 'List yield farming opportunities' indicate data retrieval with filtering options (chain, protocol, minimum APY, stablecoin-only pools).
Attacks that exploit this kind of access
List yield farming opportunities across DeFi protocols. Supports filtering by chain, protocol, minimum APY, and stablecoin-only pools. It is categorised as a Read tool in the MoltLlama MCP Server, which means it retrieves data without modifying state.
Register the MoltLlama MCP server in PolicyLayer and add a rule for get_yields: 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 MoltLlama. Nothing to install.
get_yields 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_yields 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 get_yields. 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.
get_yields is provided by the MoltLlama MCP server (moltllama/moltllama). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
