THE RISK

Low Risk

Why getLatestTokens needs a policy

This is a data retrieval tool that queries public market information from Dexscreener. It performs no writes, deletions, code execution, or financial transactions. The worst-case misuse would be gathering information for malicious purposes, but the tool itself has no side effects. Low severity reflects the read-only nature and minimal blast radius.

From the tool's definition Tool description states it 'Get[s] trending tokens from Dexscreener with market data' — purely retrieves data (USD price, 24h volume, 24h price change) without modifying any state or triggering transactions.

POLICY

How to control getLatestTokens

PolicyLayer is an MCP gateway — it sits between your AI agents and Agentek Eth, and nothing reaches the server without passing your rules. This is the rule we recommend for getLatestTokens:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "getLatestTokens": {}
  }
}

getLatestTokens is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Agentek Eth — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
