Authorize payment for an approved order via POST /v2/checkout/orders/{id}/authorize. Use after the buyer approves an order with intent=AUTHORIZE. Returns the created authorization (capture later with capture_authorization).
AI agents use authorize_order to commit financial operations through Mcp Ap2 — usually the final step of a payment, billing, or trading workflow. A call moves real money.
This tool authorizes a payment against a buyer-approved order, directly committing a financial obligation. Misuse could authorize payments without proper intent, leading to unauthorized financial commitments. It falls squarely in the Financial category as it initiates the payment authorization pipeline, which is a critical financial operation.

Documented attack patterns abuse exactly the kind of access authorize_order gives an agent:
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 authorize_order:
{
"version": "1",
"default": "deny",
"tools": {
"authorize_order": {
"deny_if": [
{
"conditions": [],
"on_deny": "Requires human approval."
}
]
}
}
}Any call to authorize_order is blocked until a human approves it. The rest of the server keeps working.

Block by default and require explicit approval.
Register the Mcp Ap2 MCP server in PolicyLayer and add a rule for authorize_order: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mcp Ap2. Nothing to install.

Yes. Add a rate_limit block to the authorize_order rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for authorize_order. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
authorize_order is provided by the Mcp Ap2 MCP server (@codespar/mcp-ap2). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Mcp Ap2, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
