THE RISK

Medium Risk

Why create_report needs a policy

The tool creates a report request (a new resource) on the SP-API, which is a reversible write operation. It does not delete data, execute arbitrary code, or move money. The async polling pattern confirms it initiates a job rather than just reading existing data.

From the tool's definition 'Request an SP-API report. Report is generated asynchronously' — creates a report generation request, a write action that initiates a new resource/job on the server.

Documented attack patterns abuse exactly the kind of access create_report gives an agent:

POLICY

How to control create_report

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_report:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_report": {
      "limits": [
        {
          "counter": "create_report_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create_report 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 free account and register Mcp Afip — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about create_report

What does the create_report tool do? +

Request an SP-API report. Report is generated asynchronously — poll with get_report until processingStatus is DONE, then fetch the reportDocumentId. 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.

How do I enforce a policy on create_report? +

Register the Mcp Afip MCP server in PolicyLayer and add a rule for create_report: 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.

What risk level is create_report? +

create_report is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_report? +

Yes. Add a rate_limit block to the create_report 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.

How do I block create_report completely? +

Set action: deny in the PolicyLayer policy for create_report. 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.

What MCP server provides create_report? +

create_report 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.

Enforce policy on every Mcp Afip tool call.

Start from Mcp Afip, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
