Ten x402-paid tools for JSON, YAML, cron, diff, text, DNS, WHOIS, GitHub, crypto, and email.
这三项永远不会合并成一个分数:意见、测量和人气是不同的东西。
我们还没有为它写通俗的介绍。下面是我们从注册中心读取到的事实。
选择你使用的 AI 应用,然后复制设置。

你用的是哪个应用?
在上方选择你的应用。我们会记住它,下次按钮会显示“安装到 …”。
适用于网页版、桌面版和手机版 Claude:
https://penniless-json-repair.sjaman.workers.dev/mcp在终端中运行这条命令
claude mcp add --transport http penniless-data-utilities https://penniless-json-repair.sjaman.workers.dev/mcp粘贴到项目中的 .cursor/mcp.json,或 ~/.cursor/mcp.json
{
"mcpServers": {
"penniless-data-utilities": {
"url": "https://penniless-json-repair.sjaman.workers.dev/mcp"
}
}
}浏览器会先询问是否打开应用,然后应用会显示设置并请你确认。密钥的值会留空,由你自己填写。
粘贴到项目中的 .vscode/mcp.json
{
"servers": {
"penniless-data-utilities": {
"type": "http",

}
}

与注册中心里这个分类中所有活跃的服务器比较。只有当发布者拥有该仓库时,星标数才计入。
它在 1 项适用的基础检查中通过了 1 项。我们没有阅读代码。在添加密钥或令牌之前,请先看看这个服务器要求哪些权限,并使用只具备所需权限的密钥。
注册中心没有列出必需的密钥,不过有些服务器会在首次使用时要求你登录。
它在作者的云端运行。通过互联网连接,无需安装,但你发送的内容会经过作者的服务器。
GitHub 仓库最后更新于–,最新版本(3.1.0)于2个月前进入注册中心。
支持 MCP 的应用,例如 Claude Desktop、Claude Code、Cursor 和 VS Code。它通过 URL 连接,所以接受远程 MCP 服务器的应用也可以使用,例如开启开发者模式的 ChatGPT。

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:
{
"mcpServers": { "penniless-data-utilities": { "type": "http", "url": "https://penniless-json-repair.sjaman.workers.dev/mcp" } } }
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.
| MCP name | REST path | Arguments | Returns |
|---|---|---|---|
repair_json | POST /repair/json | {input} | repaired JSON + which fixes applied |
yaml_to_json | POST /yaml/tojson | {input} | parsed value + warnings |
cron_next_run | POST /cron/nextrun | {expr, after?} | next UTC fire time |
text_diff | POST /diff | {old, new, context?} | unified diff + counts |
text_extract | POST /text/extract | {input, numbers?, codeBlocks?} | text, title, headings, links, URLs, emails |
domain_whois | POST /domain/whois | {domain} | registrar, statuses, expiry, nameservers, DNSSEC |
dns_lookup | POST /dns/lookup | {domain, type?} | DoH answers for A/AAAA/CNAME/MX/TXT/NS/SOA/PTR/SRV/CAA |
github_repo_stats | POST /github/repo-stats | {repo} | stars, forks, open issues, language, license |
email_validate | POST /email/validate | {email} | syntax + live MX deliverability |
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:
import { x402Client } from "@x402/core/client";
import { registerExactEvmScheme } from "@x402/evm/exact/client"; import { wrapFetchWithPayment } from "@x402/fetch"; import { privateKeyToAccount } from "viem/accounts";
const client = new x402Client(); registerExactEvmScheme(client, { signer: privateKeyToAccount(key), networks: ["eip155:8453"] }); const pay = wrapFetchWithPayment(fetch, client);
const res = await pay("https://penniless-json-repair.sjaman.workers.dev/repair/json", { method: "POST", headers: { "content-type": "application/json" }, body: JSON.stringify({ input: "{foo: 'bar',}" }), }); // -> { ok: true, repaired: { foo: "bar" }, applied: ["unquoted-keys","single-quotes","trailing-commas"] }
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.
npm install
npm test # 133 tests, runs fully offline (facilitator + upstream are injected) npx wrangler dev npx wrangler deploy
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.
