Loco

An MCP server that lets AI assistants manage translations through the Loco API.

What it does

This MCP provides tools to:

• List, create, update, and delete translatable assets
• Get and update translations across locales
• Manage tags on your assets

Use it with your favorite tool

OpenCode

{
  "mcp": {
    "loco": {
      "type": "local",
      "command": "npx",
      "args": ["-y", "loco-mcp", "--api-key", "<your-api-key>"]
    }
  }
}

API Key Configuration

The API key can be provided in several ways. When multiple sources are available, the resolution order is:

1. Tool parameter — pass it as the apiKey parameter in a tool call (highest priority, overrides all others)
2. CLI argument --api-key <key> — pass the key directly as a command-line argument
3. Environment variable LOCO_MCP_API_KEY — set the key in your environment
4. File path --api-key-relative-path <path> — read the key from a file (path relative to the working directory)

Examples

# 1. Direct CLI argument
npx -y loco-mcp --api-key loco_abc123

# 2. Environment variable
LOCO_MCP_API_KEY=loco_abc123 npx -y loco-mcp

# 3. Read from a file
npx -y loco-mcp --api-key-relative-path .loco-api-key

You can find your API key in your Loco project under Developer Tools → API Keys (Full Access Key).
