POLICY

How to control place_trade

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

policy.json

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

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

Create a free account and register Freqtrade — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
