What is ICU MessageFormat and why should I use it?

ICU MessageFormat is a standardized syntax for handling complex pluralization, gender agreement, and locale-specific formatting in translations. It eliminates the need for multiple translation strings per concept and scales better than simple key-value i18n.

How do I authenticate with the Lingo.dev MCP server?

The server is hosted at https://mcp.lingo.dev/main and uses HTTP transport. Check the Lingo.dev documentation for any required API keys or authentication headers needed for your specific setup.

Can I use this with my existing i18n library?

Lingo.dev is built around ICU MessageFormat, which is a standard format supported by many i18n libraries. Integration depends on your current stack—consult the Lingo.dev docs for compatibility with your framework.

What locales and languages does Lingo.dev support?

As an ICU MessageFormat implementation, it supports all locales that follow the ICU standard. Refer to the Lingo.dev documentation for the complete list of tested and recommended locales.
