WHAT IT DOES

What defi_get_stablecoins does on Sperax Ecosystem Crypto & DeFI MCP Server

AI agents call defi_get_stablecoins to retrieve information from Sperax Ecosystem Crypto & DeFI MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why defi_get_stablecoins needs a policy

This is a pure data query tool that retrieves market information about stablecoins. It has no capability to modify state, execute transactions, delete data, or move funds. Even in a DeFi context, querying stablecoin metadata presents minimal risk—the worst case is an AI agent making decisions based on retrieved data, but the tool itself cannot cause harm.

From the tool's definition Tool name 'defi_get_stablecoins' and description 'Get list of all stablecoins with market cap, chain distribution, and peg data' indicate data retrieval only.

How to control defi_get_stablecoins

policy.json

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

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