安全提示

MCP 服務會接收對話中的工具呼叫請求，並可能執行外部操作。啟用前請先了解該服務能做什麼，並只授予它所需的權限。

註冊中心已驗證此服務的命名空間屬於 moneytools.dev，且該網域同時執行其端點。這可以確認發布者，但並不代表該服務的工具是安全的。

SourceWeft 的檢查只涵蓋條目是否完整、端點是否回應；不審查伺服器的程式碼，也不審查其工具的行為。

概覽

AI 產生的概覽

遠端 MCP 伺服器，提供唯讀的加密鏈上、網頁與開發者小工具：代幣安全、授權、交易解碼、DNS 與時間查詢。

可以做什麼: 檢查代幣與錢包：代幣安全模擬、ERC-20 資訊、餘額、地址画像、ENS 解析與可用性、NFT 中繼資料、Safe 多簽資訊、金庫資料
檢查與準備交易：解釋或解碼交易與 calldata、提示 EIP-712 簽章風險、產生授權撤銷方案、編碼 calldata、讀取合約、取得日誌與 ABI、查詢交易狀態
查詢市場與鏈上資料：多鏈 gas 比較、DEX 報價、穩定幣錨定、跨鏈橋狀態、依時間查區塊、RPC 健康、鏈資訊
檢查網頁與網域：HTTP 標頭、URL 中繼資料、DNS 紀錄、網域註冊資訊、robots.txt 規則、x402 端點檢查
轉換與驗證：時區、cron 排程、貨幣、單位、雜湊與編碼、JSON Schema 驗證、QR 付款連結
適用情境: 適合需要查核代幣或地址、在人工簽章前解釋與檢查交易，或快速進行 DNS、HTTP 與網域檢查的情境。也適合想大量做小型唯讀查詢、又不想自行管理 RPC 金鑰的代理程式。
執行需求: 遠端 streamable HTTP 端點；免費額度為每個工具每天 10 次呼叫，不需安裝、金鑰或錢包。更多呼叫需透過 X-API-Key 標頭（預付額度或月租方案），或按次使用 Base 上的 USDC x402 付款。需要能連線該端點及其上游資料來源。

安裝前請注意

超出每日免費額度後會產生費用：按次 x402 USDC 付款（Base 鏈）或預付額度；失敗呼叫不計費。工具皆為唯讀，不會簽章或持有資金，但撤銷與編碼工具回傳的是未簽章交易，需由人工或錢包審核後再簽章。查詢會把地址、網址與網域傳送給第三方資料提供者。

安裝

在 SourceWeft 中

開啟儀表板中的 MoneyTools Tools，將其新增到工作區。
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/dev.moneytools%2Ftools/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。
