Features

• Fetches historical stock data (configurable period)
• Calculates technical indicators (RSI, EMA-20, EMA-50)
• RESTful API endpoints
• CORS enabled
• Written in TypeScript
• Generic MCP Integration

Prerequisites

• Node.js (v14 or higher)
• Angle One API credentials
• Any MCP-supporting platform (Cursor, Copilot, etc.)

Setup

1. Clone the repository
2. Install dependencies:

   npm install
   

3. Create a .env file in the root directory with your Angle One credentials:

   ANGLE_ONE_PUBLISHER_API_KEY=your_api_key_here
   ANGLE_ONE_CLIENT_ID=your_client_id_here
   ANGLE_ONE_PIN=your_pin_here
   ANGLE_ONE_TOTP=your_totp_secret_here
   PORT=3000
   DATA_PERIOD_MONTHS=6  # Optional: Number of months of historical data to fetch (default: 6)
   

Running the Server

Development mode (with hot reload):

npm run dev

Build and run in production:

DATA_PERIOD_MONTHS=3   # Fetch 3 months of data

MCP Integration

This API is available as a generic MCP that can be used with any platform supporting the MCP protocol.

TypeScript

The project is written in TypeScript and includes type definitions for:

• API responses
• Technical indicators
• Request/Response objects
• Environment variables
