개요

제작자가 쓴 설명(영어 원문)

75 paid agent tools: website audits and research; BM25, MiniLM vector and hybrid discovery are free.

PopNx MCP의 세 기둥

이 세 가지는 절대 하나의 점수로 합치지 않아요. 의견, 측정, 인기는 서로 다른 것이니까요.

할 수 있는 일

이 서버는 아직 쉬운 말로 된 요약을 쓰지 못했어요. 아래는 레지스트리에서 읽어 온 사실이에요.

  • 연결 방식: 클라우드에서 실행
  • 전송 방식: Streamable HTTP
  • 카테고리: 검색 및 AI 기억
  • 입력해야 할 값: X-API-Key

설치

쓰고 있는 AI 앱을 고른 다음 설정을 복사하세요.

설치하기 전에

비밀로 표시된 값은 내 계정의 열쇠예요. 절대 다른 사람과 공유하거나 채팅에 붙여 넣지 마세요.

필요한 것

어떤 앱을 쓰세요?

위에서 앱을 고르세요. 기억해 두었다가 다음부터는 버튼에 “…에 설치”라고 표시해요.

이 주소는 요청 header에 키가 필요한데, 커넥터 추가 메뉴에서는 넣을 수 없어요. 대신 Claude Code, Cursor, VS Code를 쓰세요.

터미널에서 이 명령어를 실행하세요

claude mcp add --transport http hubvibe https://hubvibe-io.com/mcp --header 'X-API-Key: your-value'

실행하기 전에 빈 값을 채워 주세요.

Cursor에서 열기

또는 설정을 직접 복사하기

프로젝트의 .cursor/mcp.json 또는 ~/.cursor/mcp.json에 붙여 넣으세요

{
  "mcpServers": {

      "headers": {
        "X-API-Key": "your-value"
      }
    }
  }
}

브라우저가 앱을 열지 물어본 다음, 앱이 설정을 보여 주고 확인을 요청해요. 키 값은 비워 두니 직접 입력하세요.

HubVibe

One node, 75 machine-payable jobs, one price per call, one receipt per job. HubVibe sells work to autonomous agents over HTTP 402: 70 workers under /work/* — LLM inference, live web search and page extraction, Base chain reads, spot and prediction-market data, BigQuery analysis and forecasting, deterministic regression and probability statistics, image/speech/video generation, sandboxed Python, maps, and cited research, verification and company briefs that compose several of them in one call — plus 5 deterministic site audits (WCAG 2.1 A/AA, SEO, security headers, performance, bundle). Pay with x402 (USDC on Base) or an MPP transfer-hash credential. No account, no human in the loop, and every delivered job has a machine-verifiable receipt at /work/receipts/{id}.

Live: https://hubvibe-io.com

Building an agent platform? HubVibe also delivers custom agent discovery and purchasing infrastructure: lexical, semantic, vector and hybrid catalog routers, MCP/A2A integration, verifiable receipts, idempotency, spend limits and anti-loop controls. This is scoped professional work, separate from the pay-per-call tools below.

This public repository contains the buyer-side clients, schemas, integrations, and registry metadata needed to discover and call HubVibe. The production workers, provider configuration, payment ledger, deployment configuration, credentials, and customer data remain in the private production repository.

Every check is a deterministic rule run against the live page. Nothing here is a language model judging whether a site looks compliant, and a check that could not run is returned as an error, never as a passing result.

There are two ways in. Both take under a minute.


1 — Gate your CI on it: one step, nothing to install

- uses: Its-fortunatefolly/HubVibe@v1

with: url: https://staging.example.com wallet-key: ${{ secrets.HUBVIBE_WALLET_KEY }}

That is the entire integration. Every pull request now runs the full compliance bundle against your deployed preview and fails the build on the regression that caused it — not in an audit six months later.

  • Findings render in the job summary: rule, impact, nodes hit, link to the fix.
  • A check that failed to *execute* is an error, never a silent pass — a green build means the checks actually ran.
  • fail-on-error: false keeps our outage from ever blocking your deploy; your real regressions still gate it.
  • $0.15 per PR for all four checks as one bundle, $0.05 for a single check. A repo running 100 paid bundle audits a month spends $15. No subscription, no seat licence, no minimum.

Gate a promotion on it:

- name: Audit staging

id: audit uses: Its-fortunatefolly/HubVibe@v1 with: url: https://staging.example.com wallet-key: ${{ secrets.HUBVIBE_WALLET_KEY }}

  • name: Promote to production if: steps.audit.outputs.passed == 'true' run: ./deploy-production.sh

wallet-key is an EVM private key funded with USDC on Base. The step reads the 402, signs, and pays for its own run — no account, no checkout, nothing to provision first. max-price-usd (default 0.15) is a hard ceiling the client refuses to sign above, so fund the address like petty cash rather than a treasury. It needs no ETH: x402 signs the transfer off-chain and the facilitator pays the gas.

If you already hold a prepaid API key, pass api-key: instead of wallet-key: and the step spends that.

2 — Point your agent at it: no key, no signup, pay per call

An unauthenticated call is not an error here. It is the price sheet:

curl -i -X POST https://hubvibe-io.com/audit/wcag \

-H "Content-Type: application/json" \ -d '{"url":"https://example.com"}'

HTTP/1.1 402 Payment Required PAYMENT-REQUIRED:

{ "x402Version": 1, "error": "payment_required", "price_usd": 0.05, "accepts": [ { "scheme": "exact", "network": "base", "asset": "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913", "payTo": "0x837C40E2B4e976f43Ffb4451eE281A00fA9477dd", "maxAmountRequired": "50000", "resource": "https://hubvibe-io.com/audit/wcag", ... } ], "extensions": { "bazaar": { ... } }, "docs": "https://hubvibe-io.com/.well-known/agent.json" }

An agent reads the 402, signs an x402 payment (USDC on Base, or on Solana from the v2 header), retries with X-PAYMENT (v1) or PAYMENT-SIGNATURE (v2), and gets the audit. Payment is verified before the audit runs and settled only after it produces a result — a failed audit is never charged: x402 is settled only once the audit has run (and a settlement the facilitator refuses withholds the result and charges nothing), a prepaid key is refunded, and an MPP credential a failed audit consumed is accepted again on the retry.

For Python agents and swarms, the bundled tollbooth client does the whole loop — challenge, budget check, signing, retry — with two hard spending limits enforced *before* anything is signed:

from integrations.hubvibe_tollbooth import HubVibeTollbooth

booth = HubVibeTollbooth.from_env() # HUBVIBE_WALLET_KEY or HUBVIBE_API_KEY result = booth.audit("https://example.com") # full bundle, $0.15 result = booth.audit("https://example.com", endpoint="wcag") # $0.05

accepts lists only the payment rails that can genuinely settle on this deployment. A rail that is not configured is omitted rather than advertised with a null recipient, so a paying agent never builds a payment that cannot land.

How machines find this node without being told the URL: every 402 carries x402 Bazaar discovery data, so the facilitator catalogs this node by capability and price on the payment that settles through it — the spec has no other ingestion path; the /mcp endpoint is published in the official MCP registry as io.github.Its-fortunatefolly/hubvibe; A2A agents read /.well-known/agent-card.json; and /.well-known/agent.json is generated from the same catalog the routes charge from, so the advertised price is the charged price by construction.

Worker network (/work/*)

The same payment gate sells a wider catalog beside the audits — each worker validated for free before any payment is read, never billed for a call that produced no result, with per-provider retries, exponential backoff, failover and a circuit breaker behind it. All 70 are in the catalog; every one the node can serve is live on the public node at hubvibe-io.com (GET /work lists them, free). On any other deployment a worker whose provider is not configured is absent, with a specific reason, until it is.

A worker whose provider is not configured is absent — no route, no price, no tool, no manifest entry — the same rule the payment rails follow. See deploy/vps/.env.example for every provider key. GET /work (free) lists what is live on this deployment and why anything else is not.

Prices are flat per call and published where the audits' are: the 402 challenge, /.well-known/agent.json, /openapi.json, and the MCP tool list. Callers can send Idempotency-Key to make retries of one request return the first delivery instead of buying the work twice.

Paying

Three rails, all fail-closed — no valid credential means no job runs:

  • `X-PAYMENT` / `PAYMENT-SIGNATURE` — x402 v2, exact scheme, USDC on Base, settled through the Coinbase facilitator. This is the primary rail.
  • `Authorization: Payment ...` — MPP evm method, hash credential: the payer sends the exact USDC amount to the recipient itself and presents the transaction hash. No signature is verified, so smart-wallet payers (Coinbase Base Account and other EIP-7702 / ERC-433
