How to Set Up and Use Better i18n

Better i18n MCP Server connects AI assistants such as Claude, Cursor, and Windsurf directly to your translation workflow using the Model Context Protocol. It provides TypeScript SDKs for Next.js, React, and Expo/React Native projects together with a CLI and CDN-powered translation delivery, letting agents manage multi-language content without leaving the editor.

Prerequisites

  • Node.js 18 or newer
  • An active Better i18n project (sign up at better-i18n.com)
  • An MCP-compatible AI client (Claude Desktop, Claude Code, Cursor, or Windsurf)
  • npm, pnpm, or yarn package manager
1

Install the Better i18n MCP package

Install the MCP server package from npm. This installs the server binary along with the TypeScript SDK used by your project.

npm install @better-i18n/mcp
2

Authenticate with Better i18n

Run the CLI login command to authenticate your local environment with your Better i18n project. This stores credentials that the MCP server uses when AI agents make translation requests.

npx @better-i18n/mcp login
3

Add the MCP server to your AI client config

Register the server with your MCP client by adding an entry to claude_desktop_config.json (Claude Desktop) or the equivalent config file for your client.

4

Integrate the SDK into your frontend project

Install the framework-specific SDK for your project and wrap your app with the Better i18n provider. Translations are served from the CDN and can be updated by AI agents through the MCP server.

# Next.js
npm install @better-i18n/next

# React
npm install @better-i18n/react

# Expo / React Native
npm install @better-i18n/expo
5

Verify the connection

Open your MCP client and ask it to list available translation keys or add a new string. The agent should be able to read and update your Better i18n project without leaving the IDE.

Better i18n Examples

Client configuration

Claude Desktop configuration that starts the Better i18n MCP server using npx so no global install is required.

{
  "mcpServers": {
    "better-i18n": {
      "command": "npx",
      "args": ["@better-i18n/mcp"]
    }
  }
}

Prompts to try

Use these prompts in your AI client to manage translations via the Better i18n MCP server.

- "List all translation keys that are missing a Spanish translation"
- "Add a new translation key 'welcome_message' with English value 'Welcome to our app'"
- "Translate all missing French strings in the homepage namespace"
- "Show me all translation keys modified in the last 7 days"

Troubleshooting Better i18n

MCP server fails to start with authentication error

Run npx @better-i18n/mcp login again to refresh your credentials. Ensure your Better i18n project API key is valid in the project dashboard.

AI client does not see Better i18n tools

Verify the mcpServers entry in claude_desktop_config.json uses the exact package name @better-i18n/mcp. Restart the AI client after editing the config file. Check that Node.js 18+ is on the PATH that your client uses.

Translations not updating in the CDN after agent writes

CDN propagation may take up to 60 seconds. Check the Better i18n dashboard to confirm the write was received. If using a self-hosted CDN endpoint, verify your project settings point to the correct CDN URL.
