Why deactivate_recurrent needs a policy

This tool directly affects financial operations by stopping recurring payment charges. While 'pause' implies potential reversibility, it interrupts financial obligations and payment flows, placing it firmly in the Financial category. Misuse could halt legitimate subscription payments or service continuity, resulting in significant financial and operational impact.

From the tool's definition Deactivate (pause) a recurrent payment so it stops charging

POLICY

How to control deactivate_recurrent

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Ap2, and nothing reaches the server without passing your rules. This is the rule we recommend for deactivate_recurrent:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "deactivate_recurrent": {
      "deny_if": [
        {
          "conditions": [],
          "on_deny": "Requires human approval."
        }
      ]
    }
  }
}

Any call to deactivate_recurrent is blocked until a human approves it. The rest of the server keeps working.

Create a free account and register Mcp Ap2 — nothing to install.
Add this policy — paste it, or build it visually.
