Smartling MCP Docker

A Docker-based MCP (Model Context Protocol) server that wraps smartling-cli — the official Smartling command-line tool. This MCP server is a thin wrapper and can only do what smartling-cli supports. Refer to the smartling-cli documentation for the full list of capabilities and limitations.

Requirements

  • Docker

  • Smartling account credentials

Tools

Tool

Description

smartling-cli

Run any smartling-cli command (projects, files, mt)

smartling-ls

List files in /smartling or a subdirectory

smartling-cat

Print the contents of a file inside /smartling

Setup

1. Pull the image

docker pull smartlinginc/smartling-cli-mcp

2. Configure Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "smartling": {
      "command": "docker",
      "args": [
        "run", "-i", "--rm",
        "-e", "SMARTLING_USER_ID",
        "-e", "SMARTLING_SECRET",
        "-e", "SMARTLING_PROJECT_ID",
        "-e", "SMARTLING_ACCOUNT_ID",
        "-v", "/absolute/path/to/your/project:/smartling",
        "smartlinginc/smartling-cli-mcp"
      ],
      "env": {
        "SMARTLING_USER_ID": "your-user-id",
        "SMARTLING_SECRET": "your-secret",
        "SMARTLING_PROJECT_ID": "your-project-id",
        "SMARTLING_ACCOUNT_ID": "your-account-id"
      }
    }
  }
}

Important: The volume mount must map to /smartling inside the container. The smartling-ls and smartling-cat tools only work within that path.

SMARTLING_ACCOUNT_ID is required for most commands (files push, projects list, glossaries *, etc.). The MCP server injects it automatically as -a <account-id> — it is not natively supported by the CLI as an env var.

To use a custom smartling.yml (e.g. with file type mappings), mount it into /app/smartling.yml inside the container:

"-v", "/absolute/path/to/your/project:/smartling",
"-v", "/absolute/path/to/smartling.yml:/app/smartling.yml",

Restart Claude Desktop after editing the config.

3. Configure Claude Code

Add to your project's .claude/settings.json or run /mcp in Claude Code:

{
  "mcpServers": {
    "smartling": {
      "command": "docker",
      "args": [
        "run", "-i", "--rm",
        "-e", "SMARTLING_USER_ID",
        "-e", "SMARTLING_SECRET",
        "-e", "SMARTLING_PROJECT_ID",
        "-e", "SMARTLING_ACCOUNT_ID",
        "-v", "/absolute/path/to/your/project:/smartling",
        "smartlinginc/smartling-cli-mcp"
      ],
      "env": {
        "SMARTLING_USER_ID": "your-user-id",
        "SMARTLING_SECRET": "your-secret",
        "SMARTLING_PROJECT_ID": "your-project-id",
        "SMARTLING_ACCOUNT_ID": "your-account-id"
      }
    }
  }
}

With a custom smartling.yml:

{
  "mcpServers": {
    "smartling": {
      "command": "docker",
      "args": [
        "run", "-i", "--rm",
        "-e", "SMARTLING_USER_ID",
        "-e", "SMARTLING_SECRET",
        "-e", "SMARTLING_PROJECT_ID",
        "-e", "SMARTLING_ACCOUNT_ID",
        "-v", "/absolute/path/to/your/project:/smartling",
        "-v", "/absolute/path/to/smartling.yml:/app/smartling.yml",
        "smartlinginc/smartling-cli-mcp"
      ],
      "env": {
        "SMARTLING_USER_ID": "your-user-id",
        "SMARTLING_SECRET": "your-secret",
        "SMARTLING_PROJECT_ID": "your-project-id",
        "SMARTLING_ACCOUNT_ID": "your-account-id"
      }
    }
  }
}

Usage examples

Once configured, ask Claude naturally:

  • "List my Smartling projects"

  • "Show files available for translation"

  • "Push /smartling/en/strings.json to Smartling with URI en/strings.json"

  • "Pull Spanish translations for all JSON files into /smartling"

  • "Check translation status for my project"

  • "Machine translate /smartling/en/strings.json to French"
