Why drift_close_position needs a policy

This tool closes perpetual trading positions on Drift V2, a DeFi derivatives protocol. Closing a perp position directly commits or settles financial obligations — realizing PnL, returning or losing margin, and unwinding leveraged exposure. This is a financial transaction with potentially large monetary impact, irreversible once executed on-chain.

From the tool's definition Close a perpetual position on Drift V2 (full close or partial close with size parameter)

POLICY

How to control drift_close_position

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 drift_close_position:

policy.json

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

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