This diagram illustrates the Model Context Protocol (MCP) flow between Cursor, your MCP server, and Lokalise.

📁 Project Files

TypeScript Source Files (src/):

• src/mcp-server.ts: The main MCP server entry point for Cursor integration.
• src/mcp.ts: Shared logic for interacting with the Lokalise API (used by the server).
• src/server.ts: (Optional) HTTP server version (not required for Cursor).
• src/add-key.ts: (Optional) CLI tool for adding a key interactively (not required for Cursor).

Compiled JavaScript Files (dist/):

• dist/mcp-server.js: Compiled MCP server.
• dist/mcp.js: Compiled API logic.
• dist/server.js: Compiled HTTP server.
• dist/add-key.js: Compiled CLI tool.

Other Files:

• tsconfig.json: TypeScript configuration.
• Dockerfile: For building the Docker image of the MCP server.
• package.json: Project dependencies and scripts.
• README.md: This documentation file.

Available Scripts

• npm run build - Compile TypeScript to JavaScript
• npm run dev - Run the MCP server in development mode with tsx
• npm run server - Run the HTTP server in development mode with tsx
• npm run add-key - Run the CLI tool in development mode with tsx
• npm start - Run the compiled MCP server from dist/

Requirements

📦 Installation

# For MCP usage (global installation)
npm install -g lokalise-mcp-server

# For library usage (project dependency)
npm install lokalise-mcp-server

NPM Package: https://www.npmjs.com/package/lokalise-mcp-server

⚡️ Usage (Quick Start with Cursor MCP)

Option 1: NPM Package (Recommended)

🛠️ Add this to your mcp.json (or configure via Cursor UI):

{
  "mcpServers": {
    "lokalise": {
      "command": "npx",
      "args": ["-y", "lokalise-mcp-server"],
      "env": {
        "LOKALISE_API_KEY": "your_actual_api_key"
      }
    }
  }
}

3. 🔄 Reload Window. It will automatically use the npm package.

Option 2: Docker (Alternative)

No need to run Docker or Podman manually!

1. 🐳 Make sure Docker or Podman is installed and running.

2. 🛠️ Add this to your mcp.json (or configure via Cursor UI):

   Copy & paste — that's itCopy

   {
     "mcpServers": {
       "lokalise": {
         "command": "docker", // podman
         "args": [
           "run",
           "--rm",
           "-i",
           "-e", "LOKALISE_API_KEY",
           "rafee03/mcp-lokalise:latest"
         ],
         "env": {
           "LOKALISE_API_KEY": "your_actual_api_key"
         }
       }
     }
   }

   • You can use podman instead of docker if you prefer.
   • Cursor will automatically pull and run the image as needed.

3. 🔄 Restart Cursor. It will handle everything for you.

📝 How to Use in Cursor

This tool takes these inputs:

• projectName (required): The name of your Lokalise project (e.g., SpaceX).
• keys (required): An array of objects, each with:
  • keyName (required): The translation key (e.g., hello)
  • defaultValue (optional): The default translation value (e.g., Hello)
  • platforms (optional): The platforms this key applies to (e.g., web, ios)

Example:

I want to add two keys, one is hello and another one is bye. their default values are Hello and Goodbye. both are in web platform. the project is spaceX

Cursor will automatically convert this to the correct input for the MCP tool.
