pump_sell

THE RISK

Critical Risk

This tool directly moves/sells cryptocurrency assets (pump.fun tokens → SOL), constituting a financial transaction on-chain. Misuse by an AI agent could result in irreversible sale of tokens at unfavorable prices or unintended asset liquidation, making it critical severity under the Financial category.

From the tool's definition 'Sell a pump.fun token back to SOL' — executes a financial transaction converting cryptocurrency tokens to SOL on pump.fun's bonding curve or graduated market. 'Requires AGENTI_SOLANA_PRIVATE_KEY' confirms it signs and submits real on-chain transactions.

HOW TO CONTROL PUMP_SELL

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

policy.json

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

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

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
