## What it does

This MCP server brings Translatize translation management straight into AI development agents. Working across stdio, it gives tools like Claude Code or Cursor access to inspect, query, edit, and branch project labels.

Under the hood, the server runs on `@translatize/core`. Because it relies on native fetch, your environment needs Node.js version 18.17 or higher.

Authentication demands a machine token passed in `TRANSLATIZE_API_TOKEN`. Without this credential, the API rejects any label lookups or updates. Custom backend endpoints can also be supplied via `TRANSLATIZE_API_URL` and `TRANSLATIZE_APP_URL`.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `TRANSLATIZE_API_TOKEN`, `TRANSLATIZE_API_URL`, `TRANSLATIZE_APP_URL` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## Install

### Claude Code (native platform)

**Platform CLI**
```bash
claude mcp add --env TRANSLATIZE_API_TOKEN=<TRANSLATIZE_API_TOKEN> --env TRANSLATIZE_API_URL=<TRANSLATIZE_API_URL> --env TRANSLATIZE_APP_URL=<TRANSLATIZE_APP_URL> --transport stdio translatize-mcp -- npx -y @translatize/mcp
```
Replace <…> with your own values

### Codex

**Platform CLI**
```bash
codex mcp add translatize-mcp --env TRANSLATIZE_API_TOKEN=<TRANSLATIZE_API_TOKEN> --env TRANSLATIZE_API_URL=<TRANSLATIZE_API_URL> --env TRANSLATIZE_APP_URL=<TRANSLATIZE_APP_URL> -- npx -y @translatize/mcp
```
Replace <…> with your own values
