Overview

Description from the maker (original English)

Corporate entity resolution, VAT verification and sanctions screening via Agentum.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

  • resolve_entity

    Resolves a company to its official registry record: legal name, registration number, status, legal form, LEI, VAT. Use when onboarding a vendor, verifying a counterparty on an invoice, or enriching a company name or domain with registry IDs. Inputs: query (name, domain or registr

  • verify_eu_vat

    Validates an EU VAT number against the European Commission VIES service and returns the registered name and address. Use when validating the VAT ID on a supplier invoice, applying reverse charge on a cross-border B2B sale, or confirming a vendor's VAT registration at onboarding.

  • screen_sanctions

    Screens a company or person against OFAC SDN, EU, UN and UK FCDO sanctions lists with exact and fuzzy matching. Use when screening a counterparty before paying, checking a new vendor or customer for sanctions exposure, or re-screening a payee after a detail change. Inputs: name;

  • check_vendor

    One-call vendor KYB: registry lookup, EU VAT check and OFAC/EU/UN/UK sanctions screening with a verdict. Use when onboarding a supplier, approving a vendor before first payment, or re-checking a counterparty. Inputs: name; optional country (ISO-2), vatNumber, registrationNumber,

  • verify_bank_payee

    Validates an IBAN (ISO 13616 format, length, MOD-97 checksum) and checks the account country matches the expected payee country. Use when validating bank details on an invoice, confirming a payee's account change before paying, or checking for invoice redirection. Inputs: iban; o

  • screen_address

    Checks a crypto wallet address (EVM, Bitcoin, Tron, Solana, Litecoin) against OFAC's listed digital-currency addresses. Exact match on the official list only; not behavioural or cluster risk. Use when about to pay or send funds to an address, vetting a counterparty wallet, or che

  • batch_resolve

    Resolves 1 to 25 companies to official registry records in one call; each item works like resolve_entity. Use when onboarding a supplier list, enriching a CSV of counterparties with registration numbers and status, or deduplicating a vendor file. Inputs: items[] of {query (name,

Common questions

Is Agentum Entity Resolver safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.0) reached the registry 2 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Agentum — Global Corporate Entity, VAT & Sanctions Resolver for AI Agents

Registry availability depends on the server configuration. UK Companies House is verified locally; hosted UK access is not yet confirmed. Australian ABR and New Zealand NZBN are disabled without credentials; Japan NTA is pending approval. GLEIF lookup can still return LEI holders in these countries. Check /v1/coverage for the connected server’s current registry coverage.

Zero-Signup Streamable HTTP MCP Server & REST API for deterministic corporate entity resolution across global national registries (UK Companies House, Swiss ZEFIX, Singapore ACRA, US SEC EDGAR, European Registries, and Worldwide GLEIF LEI), live EU Commission VIES VAT validation, and OFAC SDN + EU Financial Sanctions + UN Security Council screening (26,650+ live records).
