概覽

AI 產生的概覽

遠端 MCP 端點，按次付費提供代理信任、購買前風險、交付物評估、資料與 SEO 檢查，透過 x402 以 Base 上的 USDC 結算。

可以做什麼
  • 列出付費工具與價格，並讀取非同步工作結果
  • 探測其他代理與端點：x402 報價、MCP 握手、A2A 卡片、供應方信任與品質比較
  • 稽核網站：被動站點、SEO、安全、結帳流程與交付驗證，並附簽章證明
  • 檢查交易風險：賣家信譽、價格與庫存、召回、制裁、歐盟合規、香水商品頁
  • 查詢資料：美國地址地理編碼、英國郵遞區號、電子郵件與網域郵件健康度、歐洲央行匯率
  • 依標準評估交付物並驗證其證明
適用情境
適合在整合其他付費代理或端點前做盡職調查、購買商品前查核店家與商品、依驗收標準核驗交付的網站或交付物，或取得匯率、地理編碼、制裁篩查等小型參考資料。
執行需求
遠端 streamable HTTP 端點，未宣告帳號或金鑰。初始化、工具清單與定價查詢免費。付費工具需要支援 x402 的用戶端與營運方授權的錢包，錢包需持有 Base 主網 USDC；一般 MCP 連線不會提供付款能力。限流為每 IP 每分鐘 120 次請求。
安裝前請注意
付費工具按次消耗真實 USDC，單次 0.002 至 99 USDC，應設定明確的預算策略；文件所述預算以行程為單位，結果不確定時保留額度仍會被消耗，重試前需核對回執。簽章憑證應留在伺服器端。工具會把目標網址、地址、姓名與加密貨幣地址傳送給第三方營運方。評分與證明僅供參考，任何工具都不授權購買或釋放託管資金，檢查也無法證明商品真偽或信箱可達。

README

Novarithm Agent Hub

Trust and commerce checks for agent operators, through HTTP x402 and one remote MCP endpoint. Current settlement: Coinbase CDP, USDC on Base mainnet. There are 29 paid tools and one free pricing tool at the verification dated 24 October 2026.

Start with Agent Check: inspect an x402 quote, an MCP handshake, or an A2A card before integrating another agent. These checks observe protocols and evidence; they do not certify the provider or the quality of a paid result.

Connect and inspect for free

json
{  "mcpServers": {    "novarithm": {      "type": "streamable-http",      "url": "https://gogeta2-u35175.vm.elestio.app/agents/mcp"    }  }}

The client-specific configuration format may differ. MCP initialization, tools/list, and pricing are free. Paid calls require an x402-capable client and an operator-authorized wallet; an ordinary MCP connection does not provision payment.

sh
# Node 22+; no dependencies or wallet needed for this commandnode examples/buyer.mjs quote /v1/agent/x402-probe

This only obtains an unsigned 402 quote: zero signatures and zero spending. It does not run the paid tool.

Add an explicitly bounded buyer

The example supports HTTP and MCP. Dependencies are pinned to the versions used for the free integration check. enablePaid defaults to false. No wallet is created and no paid call runs on import.

sh
cd examplesnpm installnode --test test_buyer.mjs

For a backend with an existing signer:

js
import { BASE, budgetPolicy, makePaymentClient, httpBuyer, mcpBuyer } from './buyer.mjs';
const policy = budgetPolicy({  maxPerCallAtomic: '10000',  // 0.01 USDC  totalAtomic: '20000',      // at most 0.02 USDC authorized in this process  allowedResources: [BASE + '/v1/agent/x402-probe', 'mcp://tool/x402_probe']});const paymentClient = await makePaymentClient(operatorProvidedSigner, policy);const http = await httpBuyer({client: paymentClient, allowedPaths: ['/v1/agent/x402-probe']});// Still unsigned by default. Explicit enablePaid:true permits spending under the policy.const response = await http('/v1/agent/x402-probe', {url: 'https://example.com/paid'});console.log(response.status); // 402 while enablePaid is false
const mcp = await mcpBuyer({paymentClient, allowedTools: ['x402_probe']});console.log(await mcp.pricing());await mcp.close();

Keep signer credentials server-side. The policy checks resource, recipient, chain, token, price, timeout and total authorization before signing. Reservations remain consumed after uncertain outcomes; reconcile before retrying. The budget is per process, so production operators need persistent wallet limits across restarts and instances. Tests of policy and free integration do not constitute a paid end-to-end test of this new client.

Scores are indicative. Fragrance checks do not authenticate a physical bottle. Email/DNS checks do not prove mailbox delivery. The rule-based evaluator cannot establish free-text semantic truth; a signed attestation proves the signer and the report's integrity. It holds no funds and sends no escrow transaction. Use measurable structured criteria and inspect the returned limitations.

HTTP results use {service,data}. Failed or invalid upstream requests are not settled; after an uncertain payment response, reconcile the receipt before retrying. An HTTP 200 MCP envelope may contain a tool error. The public limit is 120 requests/minute/IP, including unpaid attempts. There is no contractual availability guarantee in this repository.

Registry metadata

server.json uses the existing official registry identity com.novarithm.www/agent-hub. A GitHub merge updates repository metadata; registry publication is a separate authenticated action with domain ownership proof. Preserve the existing namespace when publishing a new version.
