WHAT IT DOES

What create_quote does on Mcp Ap2

AI agents use create_quote to commit financial operations through Mcp Ap2 — usually the final step of a payment, billing, or trading workflow. A call moves real money.

THE RISK

Critical Risk

Why create_quote needs a policy

This tool locks a foreign exchange and fee quote for fiat-to-stablecoin or stablecoin-to-fiat conversions, directly involving financial operations and committing to exchange rates. While it is a quote (not a final transaction), locking a quote in a payment protocol context creates a binding financial obligation for the TTL window and is a precursor to executing financial transfers.

From the tool's definition Lock an FX + fee quote for a 5-minute TTL. Same endpoint for both on_ramp (fiat → stablecoin) and off_ramp (stablecoin → fiat). Response carries { id, expires_at, commercial_quotation, fees }.

POLICY

How to control create_quote

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 create_quote:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_quote": {
      "deny_if": [
        {
          "conditions": [],
          "on_deny": "Requires human approval."
        }
      ]
    }
  }
}

Any call to create_quote is blocked until a human approves it. The rest of the server keeps working.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
