概覽

AI 產生的概覽

遠端 MCP 伺服器,為助理提供唯讀鏈上事實:Gas 價格、ERC-20 中繼資料、交易狀態與地址狀態,另有免費的資料需求登記。

可以做什麼
  • 查詢以太坊、Base、Arbitrum、Optimism、Polygon 的即時 Gas 價格及一般轉帳成本,可一次比較多條鏈。
  • 從合約讀取 ERC-20 的名稱、代號、精度與總供應量,並確認該地址上確實有合約程式碼。
  • 依雜湊查詢交易:狀態、所在區塊、發送方、接收方、轉移金額、Gas 用量、實際手續費與日誌數量。
  • 讀取地址的原生代幣餘額、下一個 nonce、是否為合約地址,並可同時讀取某個 ERC-20 餘額。
  • 以自然語言免費提交資料需求,並查看其他代理所提需求的彙總報告。
適用情境
適合在助理協助準備或核對加密貨幣交易時使用:需要即時 Gas 估算、正確的代幣精度、nonce 與餘額檢查,或確認交易是否已結算。也可用於在圍繞某類資料開發前,先確認是否已有可用資料來源。
執行需求
遠端 streamable HTTP 端點;未宣告任何套件、帳號、API 金鑰或環境變數。需要能連線至該提供者的端點。
安裝前請注意
所有工具皆描述為唯讀查詢,但數值取自最新區塊,鏈重組後可能改變,不能視為送出當下的保證。資料需求會被提供者收錄,請勿在其中填入敏感資訊。此伺服器不簽章、不送出交易。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 MCPFax On-Chain Toolkit,將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

Web executable,透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。

交給代理程式安裝

把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式,或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南,先向你展示發布者、端點和登入方式,經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。

閱讀 https://sourceweft.com/mcp/com.mcpscores%2Fonchain-toolkit/install.md,並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前,先告訴我它的發布者、端點和登入方式,等我確認。不要把 API 金鑰寫進命令或我會提交的檔案;問我金鑰應從哪裡取得。

request_data

Tell us what data you are looking for (free)

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.

輸入參數need必填

demand_report

What agents are asking for most (free)

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.

輸入參數days

gas_now

Current gas price on one or several chains

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.

輸入參數chain

token_info

ERC-20 token details by contract address

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

Did this transaction succeed?

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.

輸入參數hash必填chain

address_info

Balance, next nonce, and whether an address is a contract

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.
