| Tool | Description | Behaviour |
|---|---|---|
| check_transaction | Before a wallet signs a Solana transaction, simulates it on mainnet and says whether it would hand anything over: the wallet account itself, a token account's owner, a standing approval on its tokens, a close authority, stake or nonce authorities. Also lists the SOL and token amounts that would leave and arrive, flags durable nonces (a signed transaction that can be sent much later) and programs SealGuard doesn't know. Verdict: do_not_sign, review or no_red_flags. Read-only: nothing is signed or sent. Paid: needs a SealGuard API key (Authorization: Bearer sgk_…); new keys come with 20 free checks, then US$0.01 a check, or 1,000 a month included with the SealGuard guard. Keys at https://guard.2cstudio.app/mcp-key | Read-only |
| list_empty_token_accounts | Lists the SOL a Solana wallet could take back: empty token accounts (left behind by sold or sent tokens) with the rent in each and which ones SealGuard suggests closing (accounts for tokens the owner will likely receive again, or used in the last 30 days, are marked to keep, with the reason); pump.fun and PumpSwap deposits; small balances worth under US$1 that could be sold for SOL through Jupiter; and NFTs whose burn would return their rent. Selling and burning are never suggested by default: they're the owner's call. Read-only; returns a link where the owner can do it. | Read-only |
| list_token_approvals | Lists every token approval (delegate) on a Solana wallet: which address can still move which token, and how much. Also lists Token-2022 permanent delegates, which holders can't revoke. Read-only; returns a link where the owner can revoke approvals for free. | Read-only |
| scan_wallet | Checks a Solana wallet for risks and gives a 0-100 safety score: open token approvals, phishing airdrops, Token-2022 permanent delegates and transfer restrictions, stake and nonce accounts controlled by someone else, and whether the wallet account itself has been taken over. Also totals the SOL the wallet could take back: empty token accounts, pump.fun deposits, small balances it could sell, and NFTs it could burn. Read-only; returns a link where the owner can fix what was found. | Read-only |
