# nuxt-i18n-mcp

An MCP server that lets your coding agent manage translations in Nuxt projects: spot missing keys, drop dead ones, rename across every locale.

## What it does

The server exposes your project's translations to an agent. It reports which keys are still untranslated, which no longer appear in code, and can rename a key across all locales and layers in one go. Everything runs on `@the-i18n-kit/cli`, the same library behind the terminal tool.

Because `@the-i18n-kit/nuxt` publishes the layer graph Nuxt has already resolved, the server knows where a key came from in a monorepo and where it is used in the wrong place. It starts through `npx`, so there is nothing to install globally.

On a Nuxt app with several locales this replaces a lot of manual file-by-file checking — you ask the agent what is missing instead. If your translations live in a single file with no layers, expect less out of it.

## Requirements
- Needs: Node.js (commands run via npx)

## Install

### Claude Code (native platform)

**Platform CLI**
```bash
claude mcp add nuxt-i18n-mcp -- npx -y nuxt-i18n-mcp
```

### Codex

**Platform CLI**
```bash
codex mcp add nuxt-i18n-mcp -- npx -y nuxt-i18n-mcp
```

### Cursor

**Config file**
File `.cursor/mcp.json`:
```json
{
    "mcpServers": {
        "nuxt-i18n-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "nuxt-i18n-mcp"
            ]
        }
    }
}
```

### GitHub Copilot

**Config file**
File `.vscode/mcp.json`:
```json
{
    "servers": {
        "nuxt-i18n-mcp": {
            "type": "stdio",
            "command": "npx",
            "args": [
                "-y",
                "nuxt-i18n-mcp"
            ]
        }
    }
}
```

### Gemini CLI

**Platform CLI**
```bash
gemini mcp add nuxt-i18n-mcp npx -y nuxt-i18n-mcp
```

## When to use it
- find keys that no locale has translated yet
- remove dead keys left behind after a refactor
- rename a key across all locales and layers at once
- check translation coverage per locale
- trace which layer a key came from in a monorepo

## Example prompts
- List the translation keys missing from the `de` locale
- Find dead i18n keys and show where they are still referenced
- Rename the key `home.hero.title` in every locale
