Why send_edu needs a policy

This tool transfers native cryptocurrency (EDU tokens) from one wallet to another. Moving crypto assets is a financial operation that is irreversible once confirmed on-chain. Misuse could result in permanent loss of funds, warranting critical severity.

POLICY

How to control send_edu

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

policy.json

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

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