할 수 있는 일

도구 이름과 설명은 서버가 2026년 11월 7일에 알려 준 그대로예요. 우리가 아니라 제작자가 쓴 글이고, 일반 텍스트로만 보여 드려요.

  • check_tx

    Run on every transaction before signing. Shows what each wallet gains and loses, blocks drainer tricks, and catches failures and expired blockhashes before you pay a fee. Decodes each step, dry-runs it on live mainnet, finds each wallet's SOL and token changes, and answers OK, RE

  • tx_matches

    Run just before signing a transfer built from a request like "send 5 USDC to X", or a swap built for "swap 1 USDC for JUP". Confirms it moves exactly that token, amount and recipient, nothing more, or that the swap sells exactly that amount and pays the bought token back to you.

  • explain_tx

    Run after a transaction lands or fails, to report what happened instead of guessing from logs. For failures it names the failing program and the fix. Reads a confirmed transaction: whether it worked, the fee, each wallet's SOL and token changes, the programs used, and why it fail

  • fee

    Run before setting a priority fee. Gives the price in the unit Compute Budget expects (micro-lamports per compute unit) and the total in SOL, so a unit mix-up never overpays. Turns what recent transactions paid for priority into three prices: cheap, normal, fast. Pass your transa

  • tx_version

    Run when code can't find or read a transaction that is on chain, or before relying on code that reads other people's transactions. Says whether a transaction is legacy, version 0 or version 1, and which readers (RPC settings and library versions) can read it. Example: {"tx_id": "

  • build_tx

    Run when an agent needs to send SOL or a token, or swap through Jupiter: it returns the unsigned transaction already checked, with ready_to_sign and the reasons. Sign only when ready_to_sign is true. Builds a SOL or token transfer, or a Jupiter swap, as an unsigned transaction wi

  • find_token

    Run whenever a user names a token ("buy BONK"). Tickers aren't unique; copycats reuse them. Never take an address from memory. Finds the real address for a ticker or name, ranks matches by verification and liquidity, and warns when copycats share the ticker. Example: {"name": "BO

  • token_safety

    Run before buying, accepting or recommending a token. Answers SAFE, CAUTION or AVOID with exact reasons from chain and market data, plus rug_chance (high, with reasons, or null). Simulates a real holder selling, then checks if liquidity can be pulled, the creator's record, inside

  • wallet

    Run when asked what a wallet holds or is worth. One call instead of balance + tokens + history; spam is left out of the total. SOL balance, top tokens with USD values, estimated total, and recent activity in one answer. Example: {"wallet": " "}. Cost: 25 free calls a day, then $0

  • trace

    Run when a wallet was drained or money went missing, or before trusting an address someone gave you: follows the money and flags sweeper, pass-through and lookalike-address patterns. Follows a wallet's money through its recent transactions: net SOL and token change and the other

  • balance

    Run before sending SOL or paying fees, to confirm the wallet has enough. Never trust a remembered balance. A wallet's SOL balance, read from the chain. Example: {"wallet": " "}. Cost: 25 free calls a day, then $0.01 USDC per call (x402). Outputs explained: GET /api/tools/balance.

  • tokens

    Run to learn which tokens a wallet holds and how much. Ranked by USD value; unverified (often spam airdrop) tokens are 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 USD value where p

  • history

    Run to see a wallet's recent activity or get a real transaction ID. Never make one up. Lists a wallet's latest transactions, newest first, whether each worked, and a plain error name for failures. Example: {"wallet": " ", "how_many": 5}. Cost: 25 free calls a day, then $0.01 USDC

  • blockhash

    Run just before building a transaction to sign. Blockhashes expire in about 60-90 seconds; this says how long is left. A fresh blockhash and how many blocks (and about how many seconds) are left before it expires. Example: {}. Cost: 25 free calls a day, then $0.01 USDC per call (

  • token_account

    Run before sending a token. Tokens go to the recipient's token account, not their wallet, and models can't work that address out. Finds the token account (ATA) for a wallet and token with the token's real program, says if it exists, and prices creating it. Example: {"wallet": " "

  • whats_this

    Run when unsure what an address is, before sending to it or passing it on. SOL sent to a token or program address can be lost for good. Says what any address is (wallet, token account, token, program, stake account and more) with its key facts. Example: {"address": "EPjFWdd5AufqS

  • convert

    Run before putting any token amount in 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 with the token's real on-chain decimals. Example: {"token": "SOL", "amount": "0.5"} gives 500000

  • why_failed

    Run whenever a Solana transaction or dry run fails, before retrying. Retrying blind burns fees. Turns a Solana error (hex code, log line or RPC error) into the plain cause and fix. Offline, no chain call. Example: {"error": "custom program error: 0x1771", "program": "JUP6LkbZbjS1

Solana Pulse

Transaction safety for AI agents on Solana. It checks transactions before an agent signs them, confirms a transaction does exactly what the agent meant, gives token safety verdicts, explains failures, and converts amounts with real on-chain decimals, so agents stop losing money to hallucinated values.

  • Add it to your AI in a minute (Claude, ChatGPT, Cursor, VS Code, Codex and more): step-by-step on the Connect page
  • Live: https://solana-pulse-gateway-1021990235790.us-central1.run.app
  • MCP endpoint: POST /mcp (Streamable HTTP) or /mcp/sse
  • Listed in the official MCP Registry as io.github.Timothymycompc/solana-pulse-gateway
  • Open source (MIT) and free to use: every tool gives 25 free calls a day
  • Built on our principles: real data with its source, "unknown" instead of a guess, and no false data on the chain. A safety check doesn't make a token safe, and it can't. It looks for the known ways people get robbed with a token. "SAFE" really means "none of the traps we know about are present." Every rule exists because it matches a real scam.

Proof

  • 9 of 9 attacks caught, no false alarm: 10 cases built from real mainnet accounts and simulated against live mainnet state (wrong recipient, wrong amount, wrong token, hidden transfer, balance drain, malicious program, replayed payment...). Benchmark; benchmark/score.ts scores any other checker on the same cases.
  • No BLOCK on 200 ordinary mainnet transactions that really worked: 80 of 80 transfers and 26 of 27 swaps MATCH. How it was measured.
  • 6 bugs found in other Solana projects, all fixed by their maintainers (elizaOS, rotki, Agent402, UltiMafia, taurvia, sol-parser-sdk-nodejs): the list.
  • Uptime, measured honestly: two long outages in September and early October, explained below.

Why

Automated accounts fail on Solana far more often than people expect: a study of over 1.5 billion failed transactions found bots failing 58% of the time (Why Does My Transaction Fail?, ISSTA 2025). For AI agents the usual causes are mistakes a model makes confidently: wrong decimals, copycat tickers, invented addresses or signatures, expired blockhashes, priority fees in the wrong unit, and signing transactions whose effects nobody checked. Each tool here removes one of those mistakes and returns a verdict, the reasons and a fix.

Bugs we found, fixed by their maintainers

Since 2026-09-15 Solana has version 1 transactions (41.9% of non-vote transactions in sampled mainnet blocks, Oct 16-30). Code that asks the RPC for version 0 at most gets error -32015 on them and silently misses payments, deposits and history. We report each case with the code line, a real mainnet transaction and the one-line fix. Fixed so far:

ProjectWhat brokeFix
Agent402Solana payments sent as version 1 reported as not foundFixed by the maintainer
elizaOSCloud wallet deposits sent as version 1 couldn't be verifiedPR #38116
UltiMafiaInvoices paid with version 1 never matchedPR #3128
rotkiVersion 1 transactions silently skipped in users' historyPR #13511
taurviaVersion 1 activity shown as a blank "Transaction"PR #93
sol-parser-sdk-nodejsparseTransactionFromRpc failed on version 1PR #5

Hitting the error yourself? The fix page has the fix for each library, which versions can read version 1 (tested on mainnet), and a live checker.

tx_version"Transaction not found" for a transaction that is on chain: says whether it is legacy, version 0 or version 1, and which RPC settings and library versions can read it$0.01

Every input and returned field is documented in plain words: what an input is looking for and where to get it, what each returned value is and how it's worked out (GET /api/tools/ ). The tools and their fields were renamed in October 2026 to short, plain names (preflight_transaction became check_tx, transaction became tx, walletChanges became balance_changes). The old tool names and input names still work.

Prices apply only after a tool's 25 free calls for the day.

Every tool documents each input (with how to get it) and each returned field (with what it means and exactly how it is computed): GET /api/tools and GET /api/tools/ . GET /api/tools/ /example returns ready-to-run inputs built from live mainnet data.

Solana Agent Kit (SendAI): a plugin in agent-kit/ (solana-agent-kit-plugin-pulse on npm) turns each tool into an action (PULSE_CHECK_TX, PULSE_TOKEN_SAFETY, ...) and a method (agent.methods.pulseCheckTx(agent, { tx })). Its tool list is generated from the same registry (npm run agent-kit), and tests/agent-kit.test.ts fails if it falls behind.

Agent templates: templates/ has five small agents to fork (Vercel AI SDK, Claude Agent SDK, LangChain, elizaOS, Coinbase AgentKit). Each one checks every transfer with check_tx (must be OK) and tx_matches (must be MATCH) before signing, refuses when Pulse can't answer, and is a dry run by default.
