概覽

AI 產生的概覽

讓助理在 Base 上購買與管理常駐監控:鏈上條件、網頁變更、cron 排程、死人開關,以及多代理協調。

可以做什麼
DataSieve 為代理提供常駐基礎設施。付費工具可建立與續訂監控:Base 上的鏈上條件(錢包活動、巨鯨轉帳、價格突破、新資金池)、以 CSS 選擇器或正規表達式限定的網頁變更監控、死人開關,以及會觸發 webhook 的 cron 排程。協調工作區提供多代理的屏障與鎖。免費工具可檢查服務健康、讀取監控狀態、收取事件、發送心跳、暫停或恢復、驗證 Ed25519 觀測回執,以及取消監控。
適用情境
當助理需要在停止執行後繼續監視某些事物時使用:監控錢包或網頁、安排週期性喚醒、在長時間自主工作前設定死人開關,或協調多個子代理。免費工具不需要錢包即可使用,因此可以先試用再購買。
執行需求
透過 npm 套件 datasieve-mcp 以 stdio 在本機執行(需要 Node.js/npx)。不需要帳號或 API 金鑰。購買類工具需要 Base 上已儲值的臨時錢包私鑰,透過 DATASIEVE_PRIVATE_KEY_FILE 提供(也可用內嵌金鑰變數)。DATASIEVE_API_URL 選擇 API 位址,預設為正式端點;另有 Base Sepolia 上附水龍頭 USDC 的沙箱端點。需要網路存取。
安裝前請注意
購買類工具會花費 Base 上真實的 USDC:create_watch、renew_watch、coord_workspace、cron_next 與 x402_ping 都有標價。請使用專用臨時錢包,切勿使用主錢包,並將金鑰放在由 DATASIEVE_PRIVATE_KEY_FILE 引用的檔案中,而不是設定檔裡。監控會觸發 webhook,可能將資料傳送到第三方端點。監控 ID 與密鑰保存在本機 watches 檔案中。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Datasieve,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。

Desktop only,透過 STDIO。 STDIO 服務會啟動本機處理程序,因此需要 SourceWeft 桌面主機。

README

datasieve-mcp

MCP server for DataSieve — standing infrastructure for AI agents, paid over x402. On-chain conditions on Base (wallet activity, whale transfers, price crossings, new pools), url-change web monitoring (CSS selector / regex scoped), dead-man switches for your own agents (your agent pings a URL; silence fires the alert), cron schedules (fire a webhook every N seconds, at a time, or on a cron expression), and multi-agent coordination (barriers + locks). Every event carries a signed Ed25519 observation receipt. No account, no API key: one gasless USDC payment per watch, signed locally — your key never leaves your machine. Failed calls are never billed.

Setup — no key required to start

sh
claude mcp add datasieve -- npx -y datasieve-mcp

Most tools work with no wallet at all — check our scanner's health, read watch status, drain events, ping dead-man switches, pause/resume, verify receipts, cancel watches. Only the buying tools spend money.

The Claude Code skill (recommended)

sh
npx -y datasieve-mcp --install-skill

Installs a skill into ~/.claude/skills/datasieve/ that teaches Claude when to reach for standing infrastructure proactively: arm a dead-man switch before long autonomous work, schedule wake-ups, watch pages and wallets, coordinate sub-agents.

When you want to buy

x402 means paying is a signature, so purchases need a key. Two rules:

  1. Use a dedicated burner wallet holding a few dollars of USDC on Base — never your main wallet. Payments are gasless (EIP-3009), so it needs no ETH.
  2. Keep the key out of config files — point at a file instead:
sh
echo '0xYOUR_BURNER_KEY' > ~/.datasieve/key.txt && chmod 600 ~/.datasieve/key.txtclaude mcp add datasieve -e DATASIEVE_PRIVATE_KEY_FILE=$HOME/.datasieve/key.txt -- npx -y datasieve-mcp

(DATASIEVE_PRIVATE_KEY=0x... inline also works if you prefer.)

The key never leaves the process: each payment is a signature authorizing exactly the route price — one at a time, nothing standing. Run payment_status to see the wallet, its balance, and prices before spending anything.

Rehearse for free

sh
claude mcp add datasieve-sandbox -e DATASIEVE_API_URL=https://staging.datasieve.xyz \  -e DATASIEVE_PRIVATE_KEY_FILE=$HOME/.datasieve/key.txt -- npx -y datasieve-mcp

Same API, Base Sepolia, faucet USDC. Sandbox watches last 1 hour.

Watch ids and secrets are remembered in ~/.datasieve/watches.json (mode 600), so follow-up calls only need the watch id — the persistent memory your ephemeral agent lacks.
