What is the REST Countries Alternative MCP Server?
Connect your AI agent to the REST Countries database to retrieve instant, accurate information about any nation or territory in the world. This server provides a powerful interface to query geographic, economic, and political data through natural conversation.
What you can do
- Comprehensive Search — Find countries by common or official names, capital cities, or international codes (ISO 3166-1).
- Economic & Linguistic Data — Query countries based on the currencies they use or the languages spoken by their citizens.
- Regional Filtering — Browse nations by continent (Region) or specific subregions to analyze geographic clusters.
- Demographics & Identity — Search by demonyms (what citizens are called) or check independence status.
- Localized Results — Search for countries using translated names in various languages.
How it works
- Subscribe to this server
- Since this is a public API, no specific token is required (enter 'public' if prompted)
- Start asking about world geography and country statistics in Claude, Cursor, or any MCP client
Who is this for?
- Data Analysts — quickly gather country-level metadata for research and reporting
- Developers — verify ISO codes, currency formats, and language mappings without leaving the IDE
- Educators & Students — explore global facts and regional statistics through an interactive AI assistant

Frequently asked questions
How do I retrieve a list of all countries with specific data points?
Use the get_all_countries tool. You must provide a comma-separated list in the fields parameter (e.g., 'name,capital,population') to specify exactly which information you want to receive.
Can I find countries based on the currency they use?
Yes! Use the search_by_currency tool and provide the currency name or code (like 'euro' or 'USD'). The agent will return all countries where that currency is legal tender.
Is it possible to filter countries by their geographic region?
Absolutely. Use the filter_by_region tool with values like 'Europe', 'Americas', 'Asia', 'Africa', or 'Oceania' to get a list of countries in that specific part of the world.
How does the OpenAI Agents SDK connect to MCP?
Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
Can I use multiple MCP servers in one agent?
Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.
Does the SDK support streaming responses?
Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
