WHAT IT DOES

What prepare_kamino_init_user does on VaultPilot MCP

AI agents invoke prepare_kamino_init_user to trigger actions in VaultPilot MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why prepare_kamino_init_user is rated High

This tool executes an on-chain Solana transaction that initializes multiple accounts on a DeFi protocol (Kamino). It triggers external blockchain operations with real SOL costs (~0.028 SOL in rent). While not directly moving funds or being irreversible, it establishes on-chain state required for subsequent borrow/supply/withdraw operations.

From the tool's definition Creates the user lookup table + userMetadata PDA + obligation PDA ... on Kamino's main market in a single tx. Costs ~0.028 SOL total in rent. DURABLE NONCE REQUIRED. BLIND-SIGN on Ledger

RECOMMENDED RULE

The rule that runs prepare_kamino_init_user safely

PolicyLayer is an MCP gateway: it sits between your AI agents and VaultPilot MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For prepare_kamino_init_user, this is the rule to start with:

prepare_kamino_init_user Rate-limited

prepare_kamino_init_user stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Questions about prepare_kamino_init_user

What does the prepare_kamino_init_user tool do? +

First-time Kamino setup. Creates the user lookup table + userMetadata PDA + obligation PDA (VanillaObligation, tag 0) on Kamino's main market in a single tx.

Costs ~0.028 SOL total in rent for the three accounts (recoverable via Kamino's account-close flow when fully exiting). DURABLE NONCE REQUIRED. BLIND-SIGN on Ledger — Kamino's program isn't in the Solana app's clear-sign allowlist; match the Message Hash on-device after preview_solana_send.
