"address validation" matching MCP servers:

IBAN validation across 89 countries, BIC/SWIFT and Swiss clearing lookup, batch validation, payment-reference, postal-address and Swiss QR-bill checks for AI agents. Connect via MCP or the REST API. Includes free quotas, paid credits and a Pro subscription. SEPA and country-risk indicators support payment-data checks; they do not confirm account ownership or replace beneficiary AML/KYC screening.

Provides a validation suite for VAT, IBAN, email, geo lookup, and VIN decoding, with per-call pricing and optional x402 payment support.

Check a backtest before trusting it: deflated Sharpe, CSCV overfitting, minimum track record length, breadth ceiling and paper-evidence checks. Deflated Sharpe and track record are tested in CI against the papers' worked examples, CSCV against CRAN pbo. Runs hosted with no signup, or fully on your machine in private local mode. Also reads SEC-reported company financials by ticker.

Enables real-time validation of EU VAT numbers using the official VIES service. Supports all 27 EU member states with automatic country code detection and provides company information for valid VAT numbers.

An MCP server that exposes ISO 20022 postal-address classification, assessment, and remediation tools for AI agents, enabling them to prepare debtor/creditor addresses for the November 2026 structured-address cutover.

Enables Claude to act as an independent credit-model validator: it runs discrimination, calibration, population stability and variable stability tests on a local PD model output file, then checks every number in a draft report against a ledger of tool-computed values before saving. Reports containing any figure the code did not compute are refused, so grounding is enforced rather than requested.

MCP server that allows querying Hyperliquid open positions and unrealized PnL for any wallet address.

IBAN validation, extraction, format specs, and BIC/SWIFT lookup tools for AI assistants, backed by ibanchecker.cash. Covers 90 countries; no IBAN data is stored.

Verified validation of structured identifiers — IBAN, payment cards, ISBN-13 and VIN — for AI agents. Runs the real checksum algorithms (mod-97, Luhn, mod-10, ISO 3779) instead of letting the model guess, and returns structured results with clear errors.

Enables AI agents to discover, retrieve, compare, and analyze trusted macroeconomic statistics from central banks and international organizations, resolving concepts to official series with provenance and validation.

MCP server for ISO 20022 acmt.001 Account Opening (and companion acmt.* messages): message-type discovery, required-field lookup, JSON Schema introspection, IBAN/BIC/LEI validation, flat-record validation, and validated acmt XML generation.

Official MCP server: EU VAT validation via VIES, plus offline rates and format checks.

An MCP server that exposes the pacs008 ISO 20022 FI-to-FI Customer Credit Transfer library as tools for AI agents and assistants, enabling generation, validation, and parsing of pacs.008 credit transfer XML messages.

Provides tools for El Salvador electronic invoicing (DTE), including IVA calculation, document-type catalog, and DUI/NIT validation.

Validates EU electronic invoices (Peppol, XRechnung, FatturaPA, etc.) and explains validation error codes, enabling AI coding agents to check invoice validity and get fixes before rejection.

Generates and validates ISO 20022 Exceptions & Investigations payment cancellation messages (camt.056) with XSD validation.

An AI-native MCP server for Saudi e-invoicing that generates ZATCA-compliant invoices, QR codes, and XML from natural language, with validation and Phase 2 signing capabilities.

Latin American business compliance suite — 28 tools for tax ID validation (CPF, CNPJ, RFC, RUT, CUIT, NIT), banking (PIX, CLABE, CBU), VAT rules, e-invoicing (NF-e, CFDI, DTE), holidays, and labor calendar across Brazil, Mexico, Chile, Argentina, and Colombia.

Enables MCP agents to verify Spanish companies by CIF against the BORME, returning registry data, recent acts, and explainable 0–100 risk scoring. Also exposes the x402 payment challenge (price, network, asset, pay-to address) so a wallet the user controls can settle it and the verification can be retried.

Enables AI agents to safely query FINOS data standards with typed, read-only tools for AIGF risks and controls, CDM type and validation, and FDC3 intents and context schemas.
