概覽

AI 產生的概覽

託管式 MCP 伺服器,可查驗與比對原生 USDC 轉帳、產生鏈上證明 PDF、稽核 DNS/TLS,並執行付費的文件、OCR 與音訊工作。

可以做什麼
  • 查驗、比對並產出 USDC 付款證明:依交易雜湊查驗轉帳、確認精確收款位址與六位小數金額、產生 base64 證明 PDF。
  • 稽核單一公開主機名稱的 DNS 紀錄與 TLS 憑證。
  • 透過需驗證的中繼抓取公開 HTTPS 頁面、擷取可見文字,或以內容雜湊監測變更。
  • 處理文件:擷取 PDF 文字、對掃描檔做 OCR、抽取發票欄位、拆分或合併 PDF、轉寫影音。
  • 追蹤預付工作:讀取工作狀態與附 SHA256 的結果,查詢共用額度錢包餘額。
  • 免費探索付費工具目錄與上線狀態。
適用情境
適合需要把加密付款與預期錢包及金額核對,或提供會計可下載鏈上證明的情境。也適合希望用單一託管端點完成付費 OCR、發票抽取、PDF 處理與音訊轉寫的團隊。
執行需求
遠端 Streamable HTTP 端點,不需本機套件。免費探索與未付款的 402 詢價不需錢包。付費區塊鏈與網域工具需要支援 x402 的錢包用戶端,在 Base 或 Solana 簽署原生 USDC;一般 MCP 用戶端無法自動付款。處理中繼需在 Authorization 標頭提供 Agent Tools Bearer 金鑰,並具備預付額度或已接受的報價。
安裝前請注意
付費工具每次呼叫都會花費真實 USDC(例如 0.02 至 0.05 USDC),授權前請核對 PaymentRequired 中的金額、資產與收款位址。切勿提供助記詞或私鑰,簽章應留在自己的錢包。處理中繼需要 Bearer API 金鑰,上傳的文件與音訊會傳送給第三方。證明 PDF 不是稅務發票,結果受 RPC 可用性與最終性影響。

README

Skavio Agent Tools

New verified integration: Safe x402 buyer example — Node.js + Python. Free live HTTP 402 preview with no signup or wallet, plus opt-in Base USDC paid adapter with a per-call limit. No funded purchase is made by default. No-account visual examples.

[Skavio USDC Paid Micro-APIs MCP server — mcprush tool-list rating]

Official connection metadata and documentation for Skavio LLC's hosted MCP tools and x402 HTTP API. This repository contains discovery metadata, not the production server source.

Card-funded Agent Tools processing (no crypto wallet)

For authenticated Agent Tools document, OCR, invoice and audio processing, an administrator signs in to the Agent Tools Dashboard, selects Buy credits by card, chooses $5, $10, $20, $50, $100, $200 or $500, and completes a Stripe-hosted checkout. Verified settlement funds that same bound company wallet at 1 USD = 1,000 credits. Eligible jobs can then use the company's Agent Tools key with payment_mode=prepaid. USDC top-ups remain available.

Do not mix payment rails: the separate company Agent Tools MCP endpoint is https://getskavio.com/agent-tools/mcp, and OAuth Processing MCP is https://getskavio.com/processing/mcp. The four independently priced blockchain verification/DNS tools on https://getskavio.com/mcp and the paid HTTP x402 routes still require native USDC via x402. Card credits do not authorize those four calls, and neither MCP credential can initiate card charges.

Verification as of November 7, 2026: card checkout interface and private company binding deployed, isolated security and transactional ledger tests passed, and a Stripe TEST-mode unpaid $5 checkout was created and expired. A real paid external card-to-MCP completed job E2E has not yet been verified. Agent Tools docs · Prices.

Partner review / data-handling facts: public USDC MCP integration facts. Maintainer: Skavio LLC; email: [email protected]. GitHub contains metadata and documentation, not production source. Live runtime reports 1.30.0; registry descriptor 1.1.5 is independently versioned.

New practical guide: Verify an incoming USDC transfer from an AI agent using x402 — live 0.02/0.03/0.05 USDC operation prices, free HTTP 402 discovery and payment-safe steps. Try the hosted endpoint.

LIVE — DeepSeek-only x402 HTTP Web APIs: Seven-route discovery · OpenAPI. These four paid HTTP endpoints are separate from tenant-authenticated MCP Agent Tools:

x402 HTTP toolRouteNative Base USDC per request
Web FetchPOST /x402/v1/web/fetch0.01
Web SearchPOST /x402/v1/web/search0.02
Web ExtractPOST /x402/v1/web/extract0.02
Extract + AnalyzePOST /x402/v1/web/extract/analyze0.03

All four use DeepSeek Search, Fetch or Flash with no alternate provider. An unsigned call returns an x402-v2 HTTP 402 quote; compatible clients sign and retry with PAYMENT-SIGNATURE. One real 0.01 USDC Web Fetch purchase on 28 October 2026 settled and delivered the requested result. Do not assume the other three have independent funded checkout results. Keys and signing remain in the buyer's wallet.

Separate authenticated company Agent Tools: Legacy enterprise API integration notes. Those older web operations and their provider migration are not part of this new DeepSeek-only paid HTTP release.

Use Skavio in Cursor and Claude Desktop

Connection instructions and ready-to-copy Cursor / Claude Desktop JSON · Cursor config · Claude Desktop config. The publicly discoverable MCP server is https://getskavio.com/mcp; separate OAuth-protected Processing MCP is at https://getskavio.com/processing/mcp. Plain MCP clients do not automatically process x402 payments.

Connect an MCP client using Streamable HTTP at https://getskavio.com/mcp. Discovery and the skavio_catalog tool are free. Paid invocations use x402 MCP v2: inspect PaymentRequired, then retry with an authorization supplied by your wallet client in params._meta["x402/payment"]. Keep wallet keys in your own client. Paid MCP invocations accept native Circle USDC via x402 v2 on Base (eip155:8453) or Solana (solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp). The standalone HTTP Verify, Match and Evidence PDF routes accept Base USDC only. Obtain current payment requirements from the service.

Transfer inspection supports Base, Polygon, Arbitrum, Optimism, Ethereum, Avalanche and Solana. MCP x402 payment supports Base and Solana; the standalone HTTP x402 routes remain Base-only. Evidence PDFs are not tax invoices.

HTTP documentation: https://getskavio.com/x402/docs

The three established Base USDC verification routes remain public: /x402/v1/usdc/verify, /x402/v1/usdc/match, and /x402/v1/usdc/evidence.pdf. Four additional paid DeepSeek web POST routes are listed above; all seven are indexed in the canonical discovery document.

Public unsigned challenge and discovery checks do not establish successful funded settlement or profitability. No revenue claim is made. The current public tools/list also advertises tenant-authenticated document, OCR, invoice, audio and web Agent Tools. These require a valid Agent Tools credential and cannot be used anonymously. The separate OAuth-protected Processing API and its developer kit are at https://github.com/skavio-eu/skavio-processing-api.

Published in the official MCP Registry as eu.skavio/paid-micro-apis, version 1.1.5: https://registry.modelcontextprotocol.io/v0.1/servers/eu.skavio%2Fpaid-micro-apis/versions/1.1.5. Other directory registrations are tracked separately. Prices and capabilities may change; inspect current server responses before authorizing payment.

USDC payment verification for AI agents

Skavio USDC Payment Verification — x402 API inspects native Circle USDC transfers, matches an exact recipient and decimal amount, and generates blockchain evidence PDFs. Use it for merchant payment reconciliation, accountant transaction review and agent workflows. PDF evidence is not a tax invoice or a guarantee of third-party authorization.

  • HTTP Verify: 0.02 native USDC; Match: 0.03 USDC; PDF: 0.05 USDC. Payment settles separately on Base through x402 v2. Inspection supports Base, Polygon, Arbitrum, Optimism, Ethereum, Avalanche and finalized Solana.
  • API quickstart, schemas, errors and client configurations · seven-route discovery · OpenAPI.
  • Skavio USDC Payment Verification & Proof MCP, version 1.1.5. Stable registry namespace and tool IDs are unchanged. Connect using https://getskavio.com/mcp (Streamable HTTP).
  • MCP has four paid blockchain/domain tools (verify_native_usdc, match_native_usdc_payment, usdc_transfer_evidence_pdf, domain_dns_tls_audit), two free discovery tools, and twelve separate authenticated AgentTools processing/job/wallet relays. The DNS/TLS audit is 0.05 USDC and is not a vulnerability scan.
  • A standard MCP client without a wallet x402 extension cannot automatically pay. Discovery is free. Paid MCP retries preserve params._meta["x402/payment"]; HTTP retries use PAYMENT-SIGNATURE. Never send a private key or seed phrase. No custody or automatic spending is created by adding a server.
  • PayAPI publishes separate live listings and historical settlement receipts for HTTP Verify, 0.02 USDC, exact recipient/amount Match, 0.03 USDC, and blockchain PDF evidence, 0.05 USDC. Each route was independently read back on 2026-10-17, and each prior Base USDC receipt was checked read-only. No new payment was made for this documentation update. This is blockchain evidence, not a tax invoice.
  • RPC availability and finality affect results. No fixed latency SLA is promised. EVM requests use a 32-byte 0x hash; Solana uses its transaction signature. Match takes a recipient wallet and a positive exact USDC decimal string with at most six decimal places.

Expect HTTP 402 and decode PAYMENT-REQUIRED. Inspect the exact amount, Base USDC asset and recipient before authorizing an x402 wallet client; only then retry the same request. After an ambiguous response, inspect recovery state instead of blindly paying again.

Separate Skavio PDF, OCR & Document Processing MCP, version 0.2.8, uses company OAuth at https://getskavio.com/processing/mcp and shared prepaid credits. Processing docs explain company ownership and measured jobs. Optional AgentTools relays require the caller's own key and current backend availability; preserve the idempotency key, poll status, download results and verify SHA256. HTTP /x402/v1/processing stays disabled.

verify_native_usdc

Verify native USDC transaction

Inspect a completed native Circle USDC transfer by transaction hash on a supported chain (Base, Polygon, Arbitrum, Optimism, Ethereum, Avalanche or Solana). Use for transaction evidence; use match_native_usdc_payment to require an exact recipient and six-decimal amount, or usdc_transfer_evidence_pdf to obtain a PDF. This call does not initiate transfers or establish payment to a particular invoice. Costs 0.02 USDC via x402 v2; the paid MCP accepts Base or Solana USDC subject to wallet approval. Public-chain RPC finality and availability vary.

輸入參數networktx_hash必填

match_native_usdc_payment

Match exact USDC recipient and amount

Confirm an exact native Circle USDC recipient and six-decimal transfer amount for a completed transaction on a supported EVM chain or Solana, with chain-specific finality checks. Use when reconciling a payment with an expected wallet and amount; for inspecting a transfer without expected values choose verify_native_usdc; for a PDF choose usdc_transfer_evidence_pdf. Requires tx_hash, recipient and amount, does not send funds or create an invoice. Costs 0.03 USDC via x402 v2; paid MCP wallets can pay native USDC on Base or Solana.

usdc_transfer_evidence_pdf

USDC blockchain transfer evidence PDF

Generate a bounded base64-encoded PDF containing publicly verifiable native Circle USDC transaction evidence for an existing on-chain transfer. Use when a customer or accountant needs a downloadable blockchain proof, not when you need a machine-readable exact recipient and amount check (use match_native_usdc_payment) or a simple transaction lookup (use verify_native_usdc). The PDF is not an invoice, tax receipt or authorization. No custody or transfers. Costs 0.05 USDC via x402 v2 on Base or Solana MCP.

輸入參數networktx_hash必填

domain_dns_tls_audit

Public domain DNS and TLS audit

Audit the public DNS records and TLS certificate of ONE public hostname, using bounded DNS resolution and a TLS handshake to port 443. Use for a basic hostname/certificate check; do not use for web content fetching (web_fetch), page extraction (web_extract), vulnerability scanning, port scanning or private IP networks. Input is a hostname such as example.com, not a URL. Returns TLS validity, resolved public IPs, TLS version and certificate expiry where available; no HTTP request. Costs 0.05 native USDC via x402 v2 on Base or Solana MCP.
