The reason is that current AI tools are scattered across documents, GitHub, and centralized directories, lacking an open tool registry and standardized access control. With ERC-8257 still in the draft stage, OpenSea invited developers to participate in refining the specification before the release of version 1.0.\n\nERC-8257 確認的技術架構:四層協議的分層組合.\n\nOpenSea 在說明中確認,ERC-8257 與三個相互補充的協議構成分層組合.MCP 告知代理有哪些工具可用;ERC-8004 顯示代理身份;ERC-8257 定義如何實際使用工具;x402 處理支付流程.四層各自獨立運作且互相組合,共同構成 AI 代理的完整鏈上操作基礎設施.\n\nERC-8257 的核心由兩個部分組成:\"清單\"(包含工具功能,名稱與定價資訊)和\"存取謂詞\"(一個回答單一問題的智慧合約:\"此地址是否擁有存取權限?\").謂詞可以查詢 NFT 所有權,活躍訂閱(ERC-5643),白名單,零知識證明,DAO 投票或質押閾值等鏈上狀態.OpenSea 說明,謂詞的設計模式類似於 Seaport 區域和 Uniswap v4 鉤子 - - 作為開放的可擴充點.\n\nOpenSea 說明的工具運作流程:403 到 200 的完整鏈上循環.\n\nOpenSea 在說明中提供了一個 NFT 估值工具的示範案例,完整描述了 ERC-8257 的實際運作方式.代理呼叫工具的持有者端點,謂詞回傳 403 並指示需要在 Base 上持有 CHONK NFT.代理通過 OpenSea 購買該 NFT,重試後收到 200 回應及包含低中高價格區間,置信度和可比較成交數據的完整估值報告.整個流程中沒有任何人工介入.\n\n工具開發者可透過 @opensea/tool-sdk npm 套件建置工具,並部署至 Vercel,Cloudflare 或 Express 平台.OpenSea 確認,工具發布後可設定多種存取層級,包括 NFT 持有存取,訂閱等級,席位數量限制,以及允許存取憑證在公開市場交易.支付流程通過外部協議(x402 用於小額支付,MPP 用於計量計費)處理,ERC-8257...",
