REQUEST_FUNDS

THE RISK

Critical Risk

This tool requests funds to be sent to a wallet, which constitutes a financial operation involving movement of cryptocurrency assets. Even in a testing/development context on Solana, it triggers real blockchain transactions that move tokens or SOL. The 'useful for testing/development' qualifier slightly reduces confidence but does not change the fundamental financial nature of the operation.

From the tool's definition 'Request funds' - directly requests transfer of funds/tokens to a wallet

HOW TO CONTROL REQUEST_FUNDS

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

policy.json

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

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