EU Compliance Tools (pay-per-call, x402) MCP Server

Validate an electronic invoice against EN 16931 (XRechnung, ZUGFeRD/Factur-X, Peppol BIS, UBL or CII): detects syntax and profile, checks mandatory fields, the arithmetic consistency of all totals, the VAT breakdown and category rules (reverse charge, intra-Community supply, export). Every finding carries its official business-rule code (BR-..). The result comes with a signed, independently verifiable compliance receipt. Paid tool: $0.02 per invoice via x402 (USDC on Base, Arbitrum, Polygon or Solana).

FREE, no payment required: validate an IBAN (checksum and country structure, all countries).

FREE, no payment required: validate an EU VAT ID against the live EU VIES register and get the registered name and address where the member state publishes them. Free entry tool - the paid tools in this server add sanctions screening, counterparty due diligence, VAT rules and e-invoice validation.

Computed market and commodity indicators, not a data relay: we buy raw feeds from several upstream x402 providers and compute our own disclosed indicator. Products: market_brief (crypto market regime), gas (Base gas price), yield, commodities (supply-stress score per growing belt plus farmgate prices). The scoring rule is in every response, so the result is reproducible. Paid tool: $0.002-0.04 per call via x402 (USDC on Base, Arbitrum, Polygon or Solana).

Historical time series that no upstream provider sells: they sell the current value, we archive every value we buy, so the series over days and weeks is ours alone - it cannot be copied because a competitor lacks the past. Products: gas, yield, commodities, market_brief. resolution 'raw' (every point) or 'daily' (daily median). A short series says so honestly. Paid tool: $0.008 per call via x402 (USDC on Base, Arbitrum, Polygon or Solana).

EU AI Act Article 50 disclosure for deployers, in force since 2 August 2026. Pass the AI-generated content (or only its content_sha256 - the hash-only, privacy-first path) and get a signed machine-readable provenance record, the human-readable disclosure in German and English, and the obligations that apply with their article references. We attest origin, we do not claim to detect AI in arbitrary text. Paid tool: $0.01 per call via x402 (USDC on Base, Arbitrum, Polygon or Solana); verification is free.

Turn an AI agent's own crypto spending into a bookkeeping statement: reads every USDC payment of the wallet from Base, converts each to EUR at the ECB reference rate of the payment date, groups by payee, states the VAT treatment (reverse charge for services bought abroad, Art. 44/196 VAT Directive) and returns an auditable statement with CSV export and a signed receipt. Use it to make agent micro-payments bookable. Paid tool: $0.10 per statement via x402 (USDC on Base, Arbitrum, Polygon or Solana).

Counterparty due diligence (KYB) in one call: validates an EU VAT ID against the live VIES register, screens the name against the official EU consolidated sanctions list, checks the IBAN, and returns a traffic-light verdict (clear / review / blocked) with reasons and a recommendation. Use before onboarding a new supplier, customer or payee. Paid tool: $0.02 per check via x402 (USDC on Base, Arbitrum, Polygon or Solana).

Company register lookup straight from the official national registers: Norway (Brønnøysund), Czechia (ARES), Finland (PRH/YTJ), Slovakia (RPO), Poland (KRS). Returns name, registration number, status, legal form, address and registration date in one normalised shape, with a signed receipt. Search by name (not for PL) or by registration number. Paid tool: $0.01 per lookup via x402 (USDC on Base, Arbitrum, Polygon or Solana).

Payment gate for autonomous agents: decide whether a payment may go out. Screens the payee against EU/UN/UK sanctions lists, validates the VAT ID against VIES and checks the IBAN, then answers allow or deny with reasons. Deny is the default - a payment is released only when the check comes back clear. The answer carries a signed receipt, so the decision stays provable in an audit long afterwards; verify it offline with the free library `pip install eucompliance-tools` and `from eucompliance_tools import verify`. Paid tool: $0.02 per decision.

Will this transaction go through? Six checks in one call before any gas is spent: gas vs balance, full simulation with the revert reason decoded into plain text, stuck nonces, contract-or-wallet recipient, ERC-20 allowance, and a sanctions screen of the counterparty. Straight send / do-not-send verdict with every reason. Chains: base, ethereum, arbitrum, optimism, polygon. Paid tool: $0.005 per call via x402 (USDC on Base, Arbitrum, Polygon or Solana).

Sanctions screening (AML/KYC) against three official lists in one call: EU (European Commission FSF), UN Security Council, and UK (HM Treasury OFSI) - over 12,000 listed entities, 50,000 name variants, re-indexed daily. Fuzzy matching tolerates transliteration and spelling variants. Each hit states its list, programme, reference number, regulation, countries, birth dates and the list generation date, so the result is auditable; optional lists=eu,un,uk narrows the search. Result carries a signed, freely verifiable receipt. Paid tool: $0.05 per check via x402 (USDC on Base, Arbitrum, Polygon or Solana).

Status of an on-chain transaction by hash: mined or pending, success or revert with the decoded revert reason, gas used, block and confirmations. Chains: base, ethereum, arbitrum, optimism, polygon. Paid tool: $0.002 per call via x402 (USDC on Base, Arbitrum, Polygon or Solana).

ERC-20 balance and allowance from the chain in one call: does this owner hold enough, and has it approved enough for a given spender? Live, no node of your own. Chains: base, ethereum, arbitrum, optimism, polygon. Paid tool: $0.002 per call via x402 (USDC on Base, Arbitrum, Polygon or Solana).

Fetch a web page and return it as clean markdown (or plain text), with internal and private addresses refused for safety. A reliable read tool an agent can call before acting on a link. Paid tool: $0.003 per fetch via x402 (USDC on Base, Arbitrum, Polygon or Solana).

EU VAT decision engine for invoices and e-invoicing (XRechnung, ZUGFeRD, Peppol BIS, OSS): given supplier country, customer country, B2B/B2C and goods/service it returns place of supply, whether to charge VAT, the rate, the EN 16931 VAT category code (BT-151), the exemption reason code (BT-121), ready-to-use invoice wording in English and German, and the legal article of the VAT Directive. Paid tool: $0.005 per call via x402 (USDC on Base, Arbitrum, Polygon or Solana).
