jupiter_swap

THE RISK

Critical Risk

This tool performs an on-chain cryptocurrency token swap using a private key, which directly moves financial assets. It falls squarely in the Financial category (trading/swapping tokens). The blast radius is critical because it can irreversibly exchange potentially large amounts of cryptocurrency with no undo mechanism, using the user's private key to sign and broadcast transactions to the Solana blockchain.

From the tool's definition Execute a token swap via Jupiter v6 aggregator. Best-route swap across all Solana DEXes. Requires AGENTI_SOLANA_PRIVATE_KEY.

HOW TO CONTROL JUPITER_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 jupiter_swap:

policy.json

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

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

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