Why redeem_pt needs a policy

This tool executes financial transactions involving crypto assets — either selling PT (Principal Token) on a market before maturity or redeeming the underlying asset after maturity. Both actions involve moving or liquidating financial instruments, constituting a financial operation. Misuse could result in untimely liquidation, loss of yield, or unwanted asset conversions at unfavorable prices.

From the tool's definition Redeem PT tokens: market sell before maturity or redeem underlying after maturity

POLICY

How to control redeem_pt

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

policy.json

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

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