solana_swap

THE RISK

Critical Risk

Token swapping is a direct financial transaction that exchanges one cryptocurrency asset for another at market rates. This is irreversible once committed to the blockchain, involves real monetary value, and requires a private key to authorize. Misuse by an AI agent could result in significant financial loss through unfavorable swaps, draining of wallet funds, or manipulation into bad trades.

From the tool's definition 'Swap any Solana token via Jupiter aggregator (best route)' — executes a cryptocurrency token swap on the Solana blockchain, moving financial assets. Server description states it enables agents to 'autonomously hold, spend, earn, and receive cryptocurrency'.

HOW TO CONTROL SOLANA_SWAP

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 solana_swap:

policy.json

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

Any call to solana_swap 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.
