What is the Country Data Resolver MCP Server?
When a CRM agent processes international contacts, it cannot guess that 'MK' is North Macedonia or that 'TL' is Timor-Leste. This MCP resolves any ISO 3166-1 alpha-2 code to its full name in English, Portuguese, Spanish, or French.
The Superpowers
- 249 Countries: Full ISO 3166-1 database with alpha-2, alpha-3, and numeric codes.
- 4 Languages: Country names in EN, PT, ES, and FR for multilingual CRM workflows.
Built-in capabilities (1)
Pass the alpha-2 code (e.g. "BR", "DE", "JP") and optionally a language for the name (en, pt, es, fr). Never guess country names for obscure codes. Resolves ISO country codes to full country names in 4 languages, plus alpha-3 and numeric codes. Essential for CRM and Martech agents handling international data
