Get Venus Protocol yield stats: deposits, redemptions, net balance, yield claims, and token mappings
AI agents call get_yield_overview to retrieve information from Predictfun without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs pure data retrieval from the Venus Protocol yield mechanics subgraph. It queries immutable historical and current state information without creating, modifying, deleting, or executing any operations. The blast radius of misuse is minimal—an AI agent can only view yield data, not manipulate positions, transfer funds, or trigger transactions. This is a standard Read classification.
From the tool's definition Tool retrieves and queries yield statistics (deposits, redemptions, net balance, yield claims, token mappings) with no modification or execution capabilities. The verb 'Get' and data retrieval focus confirm read-only semantics.
Attacks that exploit this kind of access
Get Venus Protocol yield stats: deposits, redemptions, net balance, yield claims, and token mappings. It is categorised as a Read tool in the Predictfun MCP Server, which means it retrieves data without modifying state.
Register the Predictfun MCP server in PolicyLayer and add a rule for get_yield_overview: 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 Predictfun. Nothing to install.
get_yield_overview 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_yield_overview 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_yield_overview. 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_yield_overview is provided by the Predictfun MCP server (paulieb14/predictfun-subgraphs). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
