Legal Entity Resolver

v1.1.0$0.007/resultEnrichment

Company domain in, the registered legal entity out: legal name, company number, jurisdiction, status, LEI and VAT number. Only returns a match when the legal names are identical after normalization, so an unresolved domain comes back null instead of a confidently wrong company number.

Install

bash
npx @mambalabsdev/mcp-legal-entity-resolver

Use Cases

  • Who buys it. Built for anyone who has a domain and needs the company behind it: KYB and onboarding, contracting and invoicing, sanctions screening, or telling apart similarly named companies before a deal.
  • Clay enrichment column. Turn a domain into a registered company number and VAT ID for KYB, contracting, and invoicing workflows.

Features

  • Legal name and company number, as the register spells them
  • Jurisdiction and status, active or dissolved, straight from the register
  • LEI, the 20 character global identifier
  • VAT number, validated live against EU VIES
  • A full audit trail of what was rejected and why
