Is com.mcpscores/onchain-toolkit live?

Yes — it answered the hub's last check (checked 38m ago). It answered 99% of checks over the last 30 days.

Is com.mcpscores/onchain-toolkit free to use?

Yes — the hub reached it with no key and no payment.

What tools does com.mcpscores/onchain-toolkit have?

6 tools: demand_report, gas_now, token_info, tx_status, address_info, request_data.

Is com.mcpscores/onchain-toolkit safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• demand_report reads unknown never probed

  FREE, no payment. The aggregate of what agents have told us they are looking for, most-requested first, with the categories nothing available yet serves.

• gas_now reads unknown never probed

  Live gas price on Ethereum, Base, Arbitrum, Optimism or Polygon — in wei and gwei, plus what a plain 21,000-gas transfer would cost in the native token, which is the number you actually budget with. Pass several chains comma-separated to compare where to execute. Call this immediately before sending a transaction: gas moves every block, so the answer is good for seconds, not minutes. Costs $0.005 USDC per call via x402 on Base.

• token_info reads unknown never probed

  Read an ERC-20's name, symbol, decimals and total supply straight from the contract on the chain you name, and confirm the address actually has code there. Use before quoting an amount or building a transfer: getting decimals wrong is the classic way to send 1,000,000x the intended value. An address with no code, or a contract that is not an ERC-20, is reported as such and is NOT charged. Costs $0.005 USDC per call via x402 on Base.

• tx_status reads unknown 12h ago

  Status of a transaction by hash: success, failed or still pending, with the block it landed in, sender and recipient, value moved, gas used, the fee actually paid, and how many logs it emitted. Use to confirm an action you took really settled rather than assuming it did. An unknown hash is reported as not_found and is NOT charged. Costs $0.005 USDC per call via x402 on Base.

• address_info reads unknown never probed

  Native balance, the next nonce to use, and whether the address holds contract code — the three things needed before sending from or to an address. Pass 'token' as well to read an ERC-20 balance for the same address in the same call. Values are read at the latest block, so a reorg can change them. Costs $0.008 USDC per call via x402 on Base.

• request_data changes data unknown never probed

  FREE, no payment. Describe in your own words the data you are trying to buy — anything, not just on-chain data — and get back whether we operate a service that supplies it, with the MCP endpoint if so. Every request is catalogued so repeatedly-requested data gets built. Nothing identifying is stored, only the words of the request.
