Compatible with every major AI agent and IDE
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

Frequently asked questions
How many countries are supported?
All 249 countries and territories in the ISO 3166-1 standard, including overseas territories and special regions.
What languages are available for country names?
English (en), Portuguese (pt), Spanish (es), and French (fr). The engine defaults to English if the requested language is not available.
Does it validate country codes?
Yes. If you pass an invalid code like 'XX', the engine returns a clear error instead of guessing. This prevents data corruption in CRM systems.
How does Mastra AI connect to MCP servers?
Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.
Can Mastra agents use tools from multiple servers?
Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.
Does Mastra support workflow orchestration?
Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
