solana_stake

THE RISK

Critical Risk

Staking SOL is a financial operation that moves cryptocurrency into a staking protocol, committing real funds. Misuse could result in unintended locking of user assets into a liquid staking contract. The requirement for a private key ('Requires AGENTI_SOLANA_PRIVATE_KEY') confirms this is an on-chain transaction with real financial consequences.

From the tool's definition 'Stake SOL via Sanctum liquid staking to earn yield' and server description 'autonomously hold, spend, earn, and receive cryptocurrency' — commits SOL to a staking contract, a financial transaction that locks funds and issues LST tokens.

HOW TO CONTROL SOLANA_STAKE

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_stake:

policy.json

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

Any call to solana_stake 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.
