getQuote

THE RISK

Low Risk

Why getQuote needs a policy

This tool queries price quotes for token swaps but does not execute any transactions, modify balances, or trigger irreversible actions. It is purely informational, similar to checking current market prices. While the cryptocurrency context and sibling tools suggest a DeFi environment with financial capabilities, this specific tool only reads/retrieves data without executing trades or moving funds.

From the tool's definition The tool description explicitly states 'Does not execute the swap' and 'Returns expected output amount and routing info', indicating it retrieves pricing data without side effects.

POLICY

How to control getQuote

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 getQuote:

policy.json

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

getQuote 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.
