discover_yields
AI agents call discover_yields to retrieve information from ProfitSpot MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Based on the tool name and the pattern of sibling tools in a DeFi intelligence MCP server, 'discover_yields' almost certainly queries or retrieves yield information across pools and chains without modifying state or executing transactions. This is a Read operation: it searches and fetches data.
From the tool's definition Tool name 'discover_yields' indicates data retrieval for yield discovery, consistent with sibling tools that analyze, calculate, and simulate (e.g., analyze_pool, calculate_impermanent_loss).
Attacks that exploit this kind of access
discover_yields. It is categorised as a Read tool in the ProfitSpot MCP MCP Server, which means it retrieves data without modifying state.
Register the ProfitSpot MCP server in PolicyLayer and add a rule for discover_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 ProfitSpot MCP. Nothing to install.
discover_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 discover_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 discover_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.
discover_yields is provided by the ProfitSpot MCP server (omniologynow-rgb/profitspot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
