Create a draft order (invoice-style quote). Can be completed later into a real order via complete_draft_order.
AI agents use create_draft_order to create or update resources in Mcp Afip — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Afip environment.
The tool creates a draft invoice/order document within AFIP's electronic invoicing system. This is a Write operation because it creates new financial records (invoices are formal documents with tax/legal implications in Argentina). The document is reversible at the draft stage (not yet submitted to authorities), so it does not rise to Destructive.
From the tool's definition create_draft_order: 'Create a draft order (invoice-style quote)' — explicitly describes creating/generating a document; 'Can be completed later into a real order' indicates reversible creation of financial data.
Documented attack patterns abuse exactly the kind of access create_draft_order 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_draft_order:
{
"version": "1",
"default": "deny",
"tools": {
"create_draft_order": {
"limits": [
{
"counter": "create_draft_order_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_draft_order stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Create a draft order (invoice-style quote). Can be completed later into a real order via complete_draft_order. It is categorised as a Write tool in the Mcp Afip MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Mcp Afip MCP server in PolicyLayer and add a rule for create_draft_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 Afip. Nothing to install.
create_draft_order is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_draft_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 create_draft_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.
create_draft_order 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.
Free to start. No card required.
