Pulled straight from the server with tools/list on 2026-10-17.
check_txread-only

Run on every transaction before you sign it. Shows what each wallet gains and loses, blocks drainer tricks, and catches failures and expired blockhashes before you pay a fee. Decodes every step, dry-runs the transaction on live mainnet, works out each wallet's SOL and token changes, and answers OK, REVIEW or BLOCK with the reasons. Inputs: tx: The transaction, base64-encoded. Signed or not. Legacy

tx_matchesread-only

Run right before signing a transfer your agent built from a request like "send 5 USDC to X". Confirms it moves exactly that token, amount and recipient and nothing else. Catches made-up amounts, wrong decimals and sneaked-in steps. Compares the transaction with what you asked for, field by field (token, exact amount, recipient, sender), flags every step that isn't part of the transfer, and checks

explain_txread-only

Run after a transaction lands (or fails) to report what really happened, instead of guessing from logs. For failures it names the program that failed and the fix. Reads a confirmed transaction and returns whether it worked, the fee, every SOL and token balance change by wallet, the programs used, and why it failed. Inputs: tx_id: The transaction's ID (its signature). network (optional): Which Sola

feeread-only

Run before setting a priority fee. Gives the price in the exact unit Compute Budget expects (micro-lamports per compute unit) and the total cost in SOL, so a unit mix-up never overpays. Turns recent on-chain priority fees into three prices: cheap, normal and fast. Pass your transaction to get its compute limit and exact cost at each price. Inputs: tx (optional): Optional. Your transaction, so fees

find_tokenread-only

Run whenever a user names a token by ticker or name ("buy BONK"). Tickers aren't unique and copycats reuse them. Never pick a token address from memory. Finds the real token address for a ticker or name, ranks the matches by verification and liquidity, and warns when copycats share the ticker. Inputs: name: The token's ticker, name or address, e.g. "BONK", "Jupiter", "USDC". Cost: 25 free calls a

token_safetyread-only

Run before buying, accepting or recommending a token. Answers SAFE, CAUTION or AVOID with the exact reasons, from on-chain and market data. Simulates a real holder selling, checks whether the liquidity can be pulled, the creator's record, insider wallet networks, what the issuer can do (mint, freeze, Token-2022 traps), verification, liquidity, holders and age, and turns that into one verdict. Inpu

walletread-only

Run when asked what a wallet holds or is worth. One call instead of balance + tokens + history, and spam is kept out of the total. SOL balance, top tokens with USD values, estimated total worth, and recent activity, in one answer. Inputs: wallet: The wallet address to sum up. network (optional): Which Solana network to read. Default "mainnet-beta" (real money). Cost: 25 free calls a day, then $0.0

balanceread-only

Run before sending SOL or paying fees, to confirm the wallet really has enough. Never trust a balance remembered from earlier in a chat. Reads a wallet's SOL balance straight from the chain. Inputs: wallet: The wallet address to read the SOL balance of. network (optional): Which Solana network to read. Default "mainnet-beta" (real money). Cost: 25 free calls a day, then $0.01 USDC per call (x402).

tokensread-only

Run when you need to know which tokens a wallet holds and how much. Ranked by USD value, with unverified (often spam airdrop) tokens flagged so you don't report fake holdings. Lists a wallet's tokens (SPL Token and Token-2022) with exact amounts, whether each is verified, and its USD value where there's a price. Inputs: wallet: The wallet address to read the tokens of. how_many (optional): How man

historyread-only

Run to see a wallet's recent activity, or to get a real transaction ID to look into. Never make up a transaction ID; get one here. Lists a wallet's latest transactions, newest first, with whether each worked and a plain error name for failures. Inputs: wallet: The wallet address to read the transactions of. how_many (optional): How many transactions to return. Default 10. network (optional): Which

blockhashread-only

Run right before building a transaction you'll sign. Blockhashes expire after about 60-90 seconds; this tells you how long is left. Gives a fresh blockhash plus how many blocks, and roughly how many seconds, are left before it expires. Inputs: network (optional): Which Solana network to read. Default "mainnet-beta" (real money). Cost: 25 free calls a day, then $0.01 USDC per call (x402). Full fiel

token_accountread-only

Run before sending a token to someone. Tokens go to the recipient's token account, not their wallet, and models can't work this address out in their heads. Works out the recipient's token account (ATA) for a wallet and token using the token's real program, checks whether it exists, and prices creating it if not. Inputs: wallet: The wallet that will own the token account (usually the recipient). to

whats_thisread-only

Run when you're not sure what an address is, before sending to it or passing it to another tool. SOL sent to a token or program address can be stuck for good. Says what any address is: a normal wallet, token account, token, program, stake account and more, with the key facts for each. Inputs: address: Any Solana address. network (optional): Which Solana network to read. Default "mainnet-beta" (rea

convertread-only

Run before putting any token amount into a transaction. "5 USDC" is 5,000,000 raw units; wrong decimals send 1,000x too much or too little. Converts between normal amounts and raw units using the token's real on-chain decimals. Inputs: token: The token, or "SOL" for SOL (9 decimals). amount: The amount to convert, as a string, e.g. "5" or "0.25". to (optional): Which way to convert. "raw" turns 5

why_failedread-only

Run whenever a Solana transaction or dry run fails, before retrying. Retrying without knowing why just burns fees. Turns a Solana error (hex code, log line or RPC error object) into the plain cause and the fix. Works offline, no chain call. Inputs: error: The error exactly as you got it: "custom program error: 0x1771", "InsufficientFundsForRent", or the RPC error object. program (optional): The pr
