MCP server for managing i18n translation files. Gives your agent 15 purpose-built tools so it can touch the keys it needs without reading whole locale files into context.

Built on @the-i18n-kit/cli, so a tool and its command produce the same result. Part of the-i18n-kit.

📖 Documentation

Quick Start

No install needed — your MCP host runs the server with npx.

Cursor — .cursor/mcp.json:

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

VS Code — .vscode/mcp.json, which uses a different key:

{
  "servers": {
    "the-i18n-mcp": {
      "type": "stdio",
      "command": "npx",
      "args": ["@the-i18n-kit/mcp@latest"]
    }
  }
}

→ Zed, Claude Desktop and the rest

Documentation
Set up the server Every host, and how to check it is working
Tools Generated from the listing a host receives
Agent contract Exit codes, gates, failure reasons, output diversion, env vars
Configuration Glossary, tone, protected locales — every field
Monorepos and layers What the agent needs to know before deleting a key

Translation modes covers what happens with and without a provider configured — including that this server returns fallback contexts for your agent rather than translating nothing.

Migrating

the-i18n-mcp was renamed to @the-i18n-kit/mcp. The old name is deprecated and receives no updates; the binary name is unchanged.
