WHAT IT DOES

What crypto.defi-yields does on Mcp

AI agents call crypto.defi-yields to retrieve information from Mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why crypto.defi-yields is rated Low

This is a data query tool that retrieves DeFi protocol information (APY, TVL, trends, risk flags) from an external API. While the server itself is 'pay-per-call tools settled in USDC' and involves crypto, this specific tool does not execute financial transactions, move money, or modify any on-chain or off-chain state. It only reads and returns yield farming data.

From the tool's definition Tool description states it 'Returns pools ranked by APY or TVL' with filtering capabilities. Uses DefiLlama data (free/keyless access). No mention of executing trades, moving funds, or modifying any state—purely data retrieval of yield rates and TVL metrics.

RECOMMENDED RULE

The rule that runs crypto.defi-yields safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For crypto.defi-yields, this is the rule to start with:

crypto.defi-yields Allowed

crypto.defi-yields is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Mcp, apply this rule, and every crypto.defi-yields call is checked against it from then on.
