THE RISK

Critical Risk

Why sell_token needs a policy

This tool performs a real financial transaction by selling tokens in exchange for SOL on a blockchain. It irreversibly moves financial assets. Given the server context of 'executing real DeFi operations' with 'live trading,' misuse could result in significant financial loss. Financial category takes highest precedence, and the blast radius is critical since it directly controls asset disposition.

From the tool's definition "Sell a token for SOL" — directly executes a live token sale transaction on a DeFi platform, moving assets

POLICY

How to control sell_token

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

policy.json

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

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