@pipeworx/libretranslate

LibreTranslate MCP — thin abstraction over any LibreTranslate-compatible instance.

Part of Pipeworx — an MCP gateway connecting AI agents to 1394+ live data sources.

Tools

• translate(text, target, source?, format?)

• detect_language(text)

• list_languages()

Related MCP server: DeepL MCP Server

Auth / endpoint

LibreTranslate's free public instances have largely shut down or migrated to paid. You must provide an instance:

• Self-host: https://github.com/LibreTranslate/LibreTranslate

• Paid: https://libretranslate.com (BYO their API key)

• Community instance that's still up

Configure via:

• Platform: gateway env vars PLATFORM_LIBRETRANSLATE_ENDPOINT (URL) and optionally PLATFORM_LIBRETRANSLATE_KEY.

• BYO: pass ?_endpoint=https://your-instance/&_apiKey=... on the gateway URL.

Data shape

Standard LibreTranslate v1 API — see the spec.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "libretranslate": {
      "url": "https://gateway.pipeworx.io/libretranslate/mcp"
    }
  }
}

Or connect to the full Pipeworx gateway for access to all 1394+ data sources:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English:

ask_pipeworx({ question: "your question about Libretranslate data" })

The gateway picks the right tool and fills the arguments automatically.
