它能做什么

工具名称和描述与服务器在 2026年11月7日报告的完全一致。这些内容由作者撰写，不是我们写的；我们以纯文本形式显示。

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:

Project	What broke	Fix
Agent402	Solana payments sent as version 1 reported as not found	Fixed by the maintainer
elizaOS	Cloud wallet deposits sent as version 1 couldn't be verified	PR #38116
UltiMafia	Invoices paid with version 1 never matched	PR #3128
rotki	Version 1 transactions silently skipped in users' history	PR #13511
taurvia	Version 1 activity shown as a blank "Transaction"	PR #93
sol-parser-sdk-nodejs	`parseTransactionFromRpc` failed on version 1	PR #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.

Tools

Tool	Prevents	Price
`check_tx`	Signing a drainer or a transaction that will fail: shows each wallet's exact gains and losses, flags approvals, authority changes and account closures, expired blockhashes and fee overpay	$0.02
`build_tx`	Hand-built transactions nobody checked: builds a SOL or token transfer, or a Jupiter swap, unsigned, then runs `check_tx` and `tx_matches` on it and says whether it's ready to sign. Never signs or sends	$0.03
`tx_matches`	A transaction that differs from what was asked ("send 5 USDC to X", or "swap 1 USDC for JUP"): compares token, exact amount, recipient and sender, checks a swap pays the bought token back to you, and flags anything extra	$0.02
`token_safety`	Buying scam tokens: SAFE / CAUTION / AVOID from a simulated sale by a real holder, whether the liquidity can be pulled, the creator's rug record, insider wallet networks, value vs. liquidity, same-ticker copies, mint and freeze powers, Token-2022 traps, verification, liquidity, who holds it and age, plus a separate `rug_chance` with its reasons	$0.02
`explain_tx`	Guessing from logs: real balance changes by wallet, programs used, and why it failed	$0.01
`find_token`	Copycat tickers: the verified token address for a ticker, with copycats counted	$0.01
`fee`	Fee unit mistakes: cheap, normal and fast prices in micro-lamports per compute unit, plus the exact cost in SOL	$0.01
`wallet`	Totals inflated by spam airdrops: holdings with USD values, priced vs unpriced, verified vs unverified	$0.01
`trace`	Guessing where money went after a drain: each transaction's net SOL and token change and the other side, where most of it went (and whether that's a wallet or program-controlled), and drain patterns with the transactions that show them (swept with someone else paying the fee, passed straight through, emptied, lookalike-address dust, dust from strangers), and a ready report: the problem in one line, every transaction with its Solscan link and the caller's local time, a confidence level with its reason, what it points to, and next steps	$0.02
`convert`	Decimal errors: normal amounts to exact raw units using the token's real decimals	$0.01
`why_failed`	Blind retries: Solana error codes in plain words, with a fix	$0.01
`whats_this`	Sending to the wrong kind of address: wallet, token account, token, program and more	$0.01
`token_account`	Wrong token accounts: Token-2022 aware address, whether it exists, and what creating it costs	$0.01
`balance`	A balance remembered from earlier in a chat: the live SOL balance	$0.01
`tokens`	Fake holdings: tokens held, ranked by USD value, with unverified (often spam) tokens flagged	$0.01
`history`	Made-up transaction IDs: a wallet's recent transactions, real and checkable	$0.01
`blockhash`	Expired blockhashes: a fresh one with the seconds it has left	$0.01
`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.

ElizaOS and Coinbase AgentKit: setup on the Connect page.

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.
