Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
balances
balances
Use when you need what a wallet or contract holds: reads the native ETH balance and ERC-20 balances (a default set of major tokens, or up to 20 token symbols/addresses you pass) for one address on Base or Ethereum in a single multicall, with human-readable amounts and USD values from Chainlink feeds, plus a total. Zero balances are omitted unless asked. Paid tool: x402 USDC on Base, $0.003 per successful call; call without payment to receive the PaymentRequired object.
dex
dex_price
Use when a token has no Chainlink feed (long-tail, new or memecoins) and you need its current market price: finds every Uniswap v3 pool of the token against WETH, USDC (and USDT on Ethereum) across fee tiers, reads each pool's price (slot0) and reserves in one multicall, converts to USD with Chainlink, and returns the price from the deepest pool plus all pools with their depth. Flags thin liquidity. Uniswap v3 only (Aerodrome and other DEXs not included). Paid tool: x402 USDC on Base, $0.002 per successful call; call without payment to receive the PaymentRequired object.
ens
ens
Use before sending funds or when you only have a human-readable name: resolves ENS names (.eth and DNS names on ENS, including offchain/wildcard resolvers via CCIP-Read such as *.cb.id) and Basenames (*.base.eth, read directly on Base) to a checksummed address; or, given an address, returns its primary ENS name and primary Basename, each forward-verified (the name must resolve back to the address). Names are normalized per ENSIP-15. Unresolvable names are not charged. Paid tool: x402 USDC on Base, $0.001 per successful call; call without payment to receive the PaymentRequired object.
gas
gas
Use before sending a transaction or to tell a user what it will cost: reads eth_feeHistory over the last 20 blocks (10th/50th/90th percentile tips), the next base fee and gas price, on Base also the L1 data fee upper bound from the OP-stack GasPriceOracle, and prices typical actions (ETH transfer 21k gas, ERC-20 transfer 65k, DEX swap 180k) in ETH and USD (Chainlink ETH/USD). Paid tool: x402 USDC on Base, $0.001 per successful call; call without payment to receive the PaymentRequired object.
price
price
Use when you need a trustworthy USD price for crypto assets (ETH, BTC, cbBTC, SOL, LINK, AAVE, stablecoins), fiat FX rates (EUR, GBP, JPY…) or metals (XAU, XAG): reads the Chainlink price feed contracts directly from Base or Ethereum in one multicall and returns price, last update time, age in seconds, a stale flag and the feed address so the value is verifiable on-chain. Up to 10 symbols per call. Paid tool: x402 USDC on Base, $0.002 per successful call; call without payment to receive the PaymentRequired object.
token
token
Use when you have a token contract address and need to know what it is: reads name, symbol, decimals and totalSupply straight from the contract (one multicall) on Base or Ethereum, confirms there is contract code at the address, and adds a Chainlink USD price when one exists for the symbol. Answers 404 (not charged) when the address is not a token. Paid tool: x402 USDC on Base, $0.001 per successful call; call without payment to receive the PaymentRequired object.
tx
tx
Use when you need to confirm or explain a transaction (e.g. verify a payment arrived): fetches the transaction, its receipt and block from Base or Ethereum and returns success/failed/pending, confirmations, timestamp, from, to, native value, gas used and fee, the 4-byte method selector, contract created, and every ERC-20 Transfer log decoded with token symbol and human amount. 404 (not charged) if the hash is unknown. Paid tool: x402 USDC on Base, $0.002 per successful call; call without payment to receive the PaymentRequired object.

ScrapeMole Onchain — questions
Answers built from our own checks of this server.
What can ScrapeMole Onchain do?
It exposes 7 tools, read directly from the server on our last check. Among them: balances, dex_price, ens, gas, price, token and 1 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
Is ScrapeMole Onchain working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 12 of 12 checks got a reply (100.0%), average response time 308 ms. The bar chart above shows every period we have measured.
How do I connect ScrapeMole Onchain?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does ScrapeMole Onchain need an API key?
No. ScrapeMole Onchain completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is ScrapeMole Onchain?
It answers our handshake in 308 ms on average, which is faster than 46% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
