AI agents invoke prepare_kamino_supply 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.
| Parameter | Type | Required | Description |
|---|---|---|---|
mint | string | Yes | Base58 SPL mint address of the asset to supply. Must be listed on Kamino's main market — refuses otherwise. Common Kamino reserves: USDC, USDT, SOL, JitoSOL, mS |
amount | string | Yes | Human-readable amount to supply (e.g. "100" for 100 USDC, "0.5" for 0.5 SOL). Decimals are resolved from the reserve's mint metadata; pass the human value, not |
wallet | string | Yes | Solana base58 wallet — funds the deposit + tx fee. Must have already run prepare_kamino_init_user. |
Parameters from the server's own tool schema.
prepare_kamino_supply triggers real processes with real consequences. An agent gone sideways doesn't fire it once — it starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.
Attacks that exploit this kind of access
Build a Kamino deposit (supply) tx. Refuses if the wallet doesn't have Kamino userMetadata + obligation already initialized — run prepare_kamino_init_user first. Validates that the mint is listed on Kamino's main market; resolves decimals from the reserve's mint metadata so callers pass human amounts ("100" = 100 USDC, "0.5" = 0.5 SOL). DURABLE NONCE REQUIRED + same Ledger blind-sign treatment as prepare_kamino_init_user. The returned tx packs [computeBudget, ATA setup if needed, reserve refresh, obligation refresh, deposit, cleanup] under v0 + Kamino's market ALTs. It is categorised as a Execute tool in the VaultPilot MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
prepare_kamino_supply accepts 3 parameters: mint, amount, wallet. Required: mint, amount, wallet. The full parameter table on this page comes from the server's own tool schema.
Register the VaultPilot MCP server in PolicyLayer and add a rule for prepare_kamino_supply: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches VaultPilot MCP. Nothing to install.
prepare_kamino_supply is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the prepare_kamino_supply rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for prepare_kamino_supply. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
prepare_kamino_supply is provided by the VaultPilot MCP server (vaultpilot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
