Ten x402-paid tools for JSON, YAML, cron, diff, text, DNS, WHOIS, GitHub, crypto, and email.
遠端 MCP 伺服器，提供九種小型資料工具——JSON 修復、YAML 轉換、cron、diff、文字擷取、DNS、WHOIS、GitHub 統計與電子郵件驗證，按次付費。
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。
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/io.github.danielarif26%2Fpenniless-data-utilities/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。把它新增到你客戶端的 mcpServers 設定中。

}Nine deterministic data and lookup tools for AI agents, paid per call in USDC. REST advertises both native MPP and x402; MCP uses x402 v2. No accounts, no API keys, no rate-limit tiers. Every tool is pure computation or a keyless public lookup — none of them call another AI model, so results are reproducible.
/health, /openapi.json, /llms.txt, /.well-known/x402$0.001 USDC per call. REST advertises native MPP plus x402 v2 (eip155:8453, scheme exact); MCP uses x402 v2.
Base x402 settlements are verified by the free-tier PayAI facilitator. Native MPP is negotiated by mppx. Recipient (payTo): 0x3D98800c64C345950E1eAaa076D88C12d1BF5F37.
Any MCP client that speaks streamable HTTP can connect directly:
The transport is stateless — no session id is issued or required, and every
request is independent. initialize and tools/list are free. An unpaid
tools/call returns an x402 payment-required payload in result.content[0].text
(and result.structuredContent); attach the signed payment as
params._meta["x402/payment"] and repeat the call.
If you use an x402-aware MCP client, @x402/mcp handles that exchange for you.
POST /diagnose is free: it classifies what is wrong with a malformed JSON
payload without returning the repaired output, so a caller can check whether
paying is worthwhile before paying.
Any x402 v2 client works. With the reference TypeScript client and a viem account:
wrapFetchWithPayment handles the 402 round-trip: it receives the requirement,
signs the USDC authorization, retries, and only returns a 200 once the
facilitator has settled.
Environment (set in wrangler.toml): X402_NETWORK, X402_FACILITATOR,
X402_PRICE, X402_PAY_TO. Production also has an encrypted Cloudflare secret
MPP_SECRET_KEY used only to authenticate MPP challenges. Wallet private keys are
never deployed to the Worker.
