What list_quotes does on Mcp Ap2

Why list_quotes needs a policy

This tool queries and returns swap quote records associated with an authenticated account. It is purely informational — no data is created, modified, deleted, or financial transactions are initiated. The 'provisional' endpoint status and reference to docs suggest it's a straightforward data-retrieval API.

From the tool's definition Tool description states 'List recent swap quotes' — a retrieval operation with no side effects. The word 'list' and 'minted' (historical records) indicate it queries existing data without modification or execution.

Documented attack patterns abuse exactly the kind of access list_quotes gives an agent:

How to control list_quotes

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Ap2, and nothing reaches the server without passing your rules. This is the rule we recommend for list_quotes:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_quotes": {}
  }
}

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

  1. Create a free account and register Mcp Ap2 — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
