Cancel an active recurrence. Future charges will stop; already-charged cycles are untouched.
AI agents use cancel_recurrence to commit financial operations through Mcp Afip — usually the final step of a payment, billing, or trading workflow. A call moves real money.
Cancelling a recurrence stops future financial charges, which is a financial operation. It commits a financial decision (ending a subscription/recurring payment) and cannot easily be reversed once cycles are missed. This falls squarely in the Financial category, which is the most severe applicable here.
From the tool's definition "Cancel an active recurrence. Future charges will stop" — terminates an active recurring billing/subscription, directly affecting financial obligations
Documented attack patterns abuse exactly the kind of access cancel_recurrence 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 cancel_recurrence:
{
"version": "1",
"default": "deny",
"tools": {
"cancel_recurrence": {
"deny_if": [
{
"conditions": [],
"on_deny": "Requires human approval."
}
]
}
}
} Any call to cancel_recurrence is blocked until a human approves it. The rest of the server keeps working.

Cancel an active recurrence. Future charges will stop; already-charged cycles are untouched. 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 cancel_recurrence: 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.
cancel_recurrence 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 cancel_recurrence 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 cancel_recurrence. 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.
cancel_recurrence 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.
