Agent Decision & Evidence Tools (MCP + X402)

Agent Decision & Evidence Tools over MCP and x402

40 machine-callable tools, including 10 free preparation, routing and verification tools. Pay only for a successfully delivered result in USDC through x402. No account, API key, subscription or minimum purchase is required.

• Live catalog: eucompliance.tools
• MCP endpoint: https://mcp.eucompliance.tools/mcp
• Exact machine-readable catalog: agents.json
• Agent guide: llms.txt
• x402 discovery: .well-known/x402

The service is built for agents that need a bounded decision or a cited piece of evidence, not an unstructured report. Paid successes return machine-readable structured content and a signed receipt. Invalid input, unavailable required evidence and tool errors are not settled.

Add the MCP server

Claude Code:

claude mcp add --transport http eucompliance https://mcp.eucompliance.tools/mcp

Claude Desktop, Cursor or another streamable-HTTP MCP client:

{
  "mcpServers": {
    "eucompliance": {
      "type": "http",
      "url": "https://mcp.eucompliance.tools/mcp"
    }
  }
}

If the right product is unclear, call the free recommend_agent_tool tool with the job, available inputs and optional price cap. It returns one to three exact catalog matches and a safe workflow without calling a model, making a payment or executing the selected tool.

Start from the job, not the catalog

The complete 40-tool list, exact input and output schemas, current prices and transport-specific HTTP offers are always published in agents.json.

Read-only chain evidence

rpc_read_batch is the broad entry point: one default chain plus optional per-request chain overrides, up to 20 allowlisted read calls, and 28 named EVM mainnets. Focused tools are also available for wallet balance, gas estimate, contract information, transaction status and ERC-20 balance/allowance. None of them signs, approves, transfers or broadcasts a transaction.

For a decision rather than raw evidence, use tx_preflight. Missing evidence is never treated as approval. Wallet-address sanctions screening is not claimed because name lists cannot clear an address.

Market evidence and decisions

Agents can buy the smallest useful observation or a complete decision:

• spot_price — multi-exchange median and spread: $0.001
• open_social_search — bounded Bluesky and Hacker News evidence: $0.002
• perp_market_data — Hyperliquid funding, open interest, premium and volume: $0.005
• market_history — archived raw or daily series: $0.008
• market_data or coin_positioning_brief — computed context with disclosed rules: $0.01
• market_decision_pack — action, confidence, reasons, risk flags and invalidation: $0.05

Every paid market result identifies its sources and freshness. The decision pack expires after 15 minutes instead of encouraging an agent to reuse stale market advice.

High-value guarded workflows

The invoice and US-import products have free preparation tools. Run them first; they validate shape and required context and return the exact paid next step. The paid tools never release a payment, place an order, create a forwarding address, book a carrier, sign a wallet transaction or broadcast anything.

invoice_to_pay_dossier_eu accepts UBL/CII XML or ZUGFeRD/Factur-X PDFs with one embedded invoice XML. An ordinary or scanned PDF is intentionally unsupported. READY_FOR_BUYER_APPROVAL is an evidence decision, not proof of delivery, internal approval, duplicate-ledger status or bank-account ownership.

Add invoice evidence to your existing approval workflow

The invoice-guard integration is a small, opt-in Python adapter for buyers. It runs the free preparation check, delegates a single capped 1.00-USDC purchase to your authorized transport, and checks the signed dossier against the exact invoice, buyer context and freshness window. A persistent journal reuses valid identical evidence and stops instead of buying again after an ambiguous timeout. Equivalent decimal amount formats share one claim. READY_FOR_BUYER_APPROVAL advances only to your existing approval stage; the adapter never signs or submits an invoice payment.

You supply the authorized MCP/x402 transport and pin the trusted receipt issuer. The adapter accepts invoice XML only; its tests are offline, not a paid end-to-end certification. Making this check mandatory is an explicit operator policy for your own workflow, not a requirement imposed on other agents or platforms.

us_import_readiness_guard is limited to declared ordinary goods from Germany or Austria to the United States. It supplies non-binding HTS evidence and readiness guidance; it is not customs clearance, a binding classification or a shipping service.

x402 payment behavior

HTTP products return an x402 v2 payment requirement with the exact amount. Payment options are published for Base, Arbitrum, Polygon and Solana. The caller signs the selected option and retries the identical request. The server never receives a wallet private key and does not perform a buyer-side transfer.

Use a payment policy that pins the exact HTTPS resource, method, network, recipient and maximum amount. The free prepare_x402_purchase_guard plus paid x402_purchase_guard workflow can check an already received x402 challenge before a buyer confirms it; it never pays the target.

Verify a delivered result

Signed receipts can be checked independently:

pip install eucompliance-verify

from eucompliance_verify import verify_receipt, PaymentPolicy

verified = verify_receipt(response_json)
decision = PaymentPolicy(max_age_hours=24).check(response_json)
if not decision.allowed:
    raise RuntimeError("receipt outside policy")

Verifier source: eucompliance-verify. VAT conformance fixtures: eu-vat-conformance.

Operator

eucompliance.tools is operated by Patrick Kaufmann, sole proprietor in Vienna, Austria. The service exposes evidence and decision APIs; it does not act as a bank, wallet signer, customs broker, freight forwarder or legal adviser.

On-chain identity: ERC-8004 agent #60255 on Base.
