THE RISK

Medium Risk

Why decline_inquiry needs a policy

This tool writes/updates the state of an inquiry by recording a rejection decision. It modifies data (inquiry status) but is not inherently destructive (the record is preserved), financial, or executing arbitrary code. The action is a status update, placing it in the Write category. Medium severity because incorrectly declining inquiries could have compliance or business impact.

From the tool's definition Mark an inquiry as declined. Records your final reject decision on the Persona inquiry for reporting and feedback.

POLICY

How to control decline_inquiry

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 decline_inquiry:

policy.json

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

decline_inquiry 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.
