概览

AI 生成的概览

托管式 MCP 服务器,可查验与核对原生 USDC 转账、生成链上凭证 PDF、审计 DNS/TLS,并运行付费的文档、OCR 与音频任务。

可以做什么
  • 查验、核对并出具 USDC 付款凭证:按交易哈希查验转账、确认精确收款地址与六位小数金额、生成 base64 凭证 PDF。
  • 审计单个公开主机名的 DNS 记录与 TLS 证书。
  • 通过需认证的中继抓取公开 HTTPS 页面、提取可见文本或做内容哈希变更监测。
  • 处理文档:提取 PDF 文本、对扫描件做 OCR、抽取发票字段、拆分或合并 PDF、转写音视频。
  • 跟踪预付任务:读取任务状态与带 SHA256 的结果,查询共享额度钱包余额。
  • 免费发现付费工具目录与上线状态。
适用场景
适合需要把加密付款与预期钱包和金额核对,或向会计提供可下载链上证明的场景。也适合希望用一个托管端点完成付费 OCR、发票抽取、PDF 处理与音频转写的团队。
运行要求
远程 Streamable HTTP 端点,无需本地安装包。免费发现与未付款的 402 询价无需钱包。付费区块链与域名工具需要支持 x402 的钱包客户端,在 Base 或 Solana 上签署原生 USDC;普通 MCP 客户端无法自动付款。处理中继需在 Authorization 头提供 Agent Tools Bearer 密钥,并具备预付额度或已接受的报价。
安装前请注意
付费工具每次调用都会花费真实 USDC(例如 0.02 至 0.05 USDC),授权前请核对 PaymentRequired 中的金额、资产与收款地址。切勿提供助记词或私钥,签名应留在自己的钱包中。处理中继需要 Bearer API 密钥,上传的文档与音频会发送给第三方。凭证 PDF 不是税务发票,结果受 RPC 可用性与最终性影响。

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.

输入参数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.
