AI agents call delete_instance to permanently remove resources in Mcp Afip — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool performs permanent deletion which cannot be undone. In a tax/invoicing system context, deleting instances of financial records or invoices would have serious compliance and audit implications.
From the tool's definition Tool name 'delete_instance' combined with description 'Delete an instance permanently' indicates irreversible deletion.
Documented attack patterns abuse exactly the kind of access delete_instance 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 delete_instance:
{
"version": "1",
"default": "deny",
"hide": [
"delete_instance"
]
} delete_instance disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Delete an instance permanently. It is categorised as a Destructive tool in the Mcp Afip MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Mcp Afip MCP server in PolicyLayer and add a rule for delete_instance: 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.
delete_instance is a Destructive 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 delete_instance 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 delete_instance. 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.
delete_instance 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.
