Shoonya MCP Server (Mock)

Description

This project is a mock Market Connectivity Protocol (MCP) server designed to simulate interactions with a Shoonya-like trading API. It provides a basic framework for testing client applications that would connect to Shoonya for order placement and market data.

Note: This is a mock server. All interactions with the "Shoonya API" are simulated through placeholder functions. No actual trading or connection to live Shoonya systems occurs.

Key Features

• Authentication:
  • /connect endpoint for client authentication.
  • Simulates Shoonya login and returns an MCP-specific session token.
• Order Management:
  • /order endpoint for placing trading orders.
  • Comprehensive validation of order parameters (data types, allowed values for exchange, order type, etc.).
  • Basic pre-trade risk checks (maximum order quantity, maximum order value for LIMIT/SL orders).
  • Returns mock responses from the "broker," including order status.
• Market Data (Mock):
  • /marketdata/subscribe endpoint to simulate subscribing to instrument data.
  • /marketdata/fetch endpoint to retrieve mock market data for subscribed instruments.
  • Simulated data includes LTP, volume, OHLC, and changes randomly on fetch to mimic a live feed.
• API Definition:
  • A detailed API definition is available in mcp_server_api_definition.md.

Setup and Running

1. Prerequisites:

   • Python 3.x
   • pip (Python package installer)

2. Installation:

   • Clone the repository (if you haven't already).
   • Navigate to the project directory.
   • Install the required dependencies:

     pip install -r requirements.txt
     

3. Running the Server:

   • To start the Flask development server:

     python mcp_server/app.py
     

   • The server will typically start on http://127.0.0.1:5000/.

API Endpoints Overview

• POST /connect: Authenticate and get a session token.
• POST /order: Place a new order. Requires Bearer token.
• POST /marketdata/subscribe: Subscribe to mock market data. Requires Bearer token.
• GET /marketdata/fetch: Fetch mock market data for subscriptions. Requires Bearer token.

Refer to mcp_server_api_definition.md for detailed request/response formats.

Current Status

• The server is a mock implementation intended for development and testing of client applications.
• All interactions that would normally go to the Shoonya trading platform are handled by placeholder functions within mcp_server/app.py.
• No real financial transactions occur.
• Further development would be required to integrate with the actual Shoonya API.
