Why intentApproveSlowTransfer needs a policy

This tool approves cryptocurrency transfers within a smart contract context. Even though it uses the word 'approves' rather than executing the transfer directly, approval is a prerequisite gatekeeping action for financial transactions on blockchain systems. An AI agent misusing this could approve unauthorized fund transfers, resulting in direct financial loss.

From the tool's definition Tool is named 'intentApproveSlowTransfer' and description states it 'approves a transfer in SLOW contract'.

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

policy.json

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

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