Record a payment against an invoice
AI agents use create_payment to commit financial operations through Mcp Afip — usually the final step of a payment, billing, or trading workflow. A call moves real money.
This tool directly records payments, which constitutes a financial operation. Even if the tool merely records an existing payment rather than transferring funds, it commits a financial obligation in the tax system. The critical severity reflects that misuse could result in unauthorized payments, tax fraud, or financial losses. Financial category takes precedence over all others per the classification rules.
From the tool's definition Tool name 'create_payment' combined with description 'Record a payment against an invoice' explicitly indicates movement of money or financial obligations.
Documented attack patterns abuse exactly the kind of access create_payment gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Afip, and nothing reaches the server without passing your rules. This is the rule we recommend for create_payment:
{
"version": "1",
"default": "deny",
"tools": {
"create_payment": {
"deny_if": [
{
"conditions": [],
"on_deny": "Requires human approval."
}
]
}
}
} Any call to create_payment is blocked until a human approves it. The rest of the server keeps working.

Record a payment against an invoice. It is categorised as a Financial tool in the Mcp Afip MCP Server, which means it involves financial transactions. Block by default and require explicit approval.
Register the Mcp Afip MCP server in PolicyLayer and add a rule for create_payment: 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 Afip. Nothing to install.
create_payment is a Financial tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the create_payment 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 create_payment. 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.
create_payment is provided by the Mcp Afip MCP server (codespar/mcp-dev-latam). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Mcp Afip, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
