WHAT IT DOES

What prepare_kamino_supply does on VaultPilot MCP

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.

RISK

Why prepare_kamino_supply is rated High

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.

RECOMMENDED RULE

The rule that runs prepare_kamino_supply 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_supply, this is the rule to start with:

prepare_kamino_supply Rate-limited

prepare_kamino_supply 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.

FAQ

Questions about prepare_kamino_supply

What does the prepare_kamino_supply tool do? +

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.

What parameters does prepare_kamino_supply accept? +

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.

How do I enforce a policy on prepare_kamino_supply? +

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.

What risk level is prepare_kamino_supply? +

prepare_kamino_supply is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit prepare_kamino_supply? +

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.

How do I block prepare_kamino_supply completely? +

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.

What MCP server provides prepare_kamino_supply? +

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.
