Why create_smart_collection needs a policy

This tool creates new data structures (smart collections with rule-based parameters) but does not execute arbitrary code, delete data, or commit financial transactions. It is reversible through deletion or modification.

From the tool's definition Tool name contains 'create' and description states 'Create a smart collection — an automated collection populated by rules'. This is a creation operation that modifies data by establishing new collection structures.

POLICY

How to control create_smart_collection

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_smart_collection:

policy.json

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

create_smart_collection 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.

How do I enforce a policy on create_smart_collection? +

Register the Mcp Afip MCP server in PolicyLayer and add a rule for create_smart_collection: 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_smart_collection? +

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

Can I rate-limit create_smart_collection? +

Yes. Add a rate_limit block to the create_smart_collection 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_smart_collection completely? +

Set action: deny in the PolicyLayer policy for create_smart_collection. 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_smart_collection? +
