Installation

NPX (Recommended)

The simplest way to use this MCP server is through npx, which allows you to run it without installing:

npx @devnagriai/devnagriai-translate-mcp API_KEY="your_devnagri_api_key"

This is ideal for integration with AI tools like Claude, GPT, Windsurf, and Cursor.

Manual Installation

If you prefer to install the server locally:

1. Clone the repository:

git clone https://github.com/DevnagriAI/devnagriai-translate-mcp.git
cd devnagriai-translate-mcp

1. Install dependencies:

npm install

1. Set up environment variables:

Create a .env file in the root directory with the following content:

DEVNAGRI_API_KEY=your_devnagri_api_key

Usage

Direct Integration

For local/private use or development, add the server to your MCP config:

{
  "mcpServers": {
    "devnagri-translation": {
      "command": "npx",
      "args": [
        "@devnagriai/devnagriai-translate-mcp",
        "API_KEY=\"your_devnagri_api_key\""
      ]
    }
  }
}

Running the Server

Start the server:

npm start

For development with auto-reload:

npm run dev

This MCP server can be used with any MCP client. For example, using the MCP CLI client:

mcp-client --transport stdio -- node src/index.js

{
  "devnagri-translation": {
    "command": "npx",
    "args": [
      "@devnagriai/devnagriai-translate-mcp",
      "API_KEY=\"your_devnagri_api_key\""
    ]
  }
}

Cursor

In Cursor's settings:

{
  "tools": {
    "devnagri-translation": {
      "command": "npx",
      "args": [
        "@devnagriai/devnagriai-translate-mcp",
        "API_KEY=\"your_devnagri_api_key\""
      ],
      "transport": "stdio"
    }
  }
}
