Kite MCP Server

Kite MCP Server

A Model Context Protocol (MCP) server for integrating with Zerodha Kite API. This server provides Claude with tools to interact with your Kite trading account.

Features

• Portfolio Management: Get positions, holdings, and orders
• Market Data: Real-time quotes, LTP, and instrument data
• Order Management: Place, modify, and cancel orders
• Account Info: Profile, margins, and authentication status
• Secure Authentication: OAuth 2.0 flow with token persistence

Prerequisites

1. Zerodha Kite Connect App: Create an app at Kite Connect
2. API Credentials: Get your API Key and Secret
3. Bun: Latest version of Bun runtime

Installation

1. Clone and install dependencies:

bun install

2. Set up environment variables:

# Edit .env with your API credentials

3. Configure your Kite Connect app with redirect URL:

http://localhost:50000/zerodha/auth/redirect

Quick Start

1. Authenticate with Kite API

bun run auth

This will:

• Start a local OAuth server
• Open your browser to Kite login
• Save your access token securely

2. Start the MCP Server

bun start

3. Configure Claude Desktop

Add to your Claude Desktop configuration:

{
  "mcpServers": {
    "kite": {
      "command": "bun",
      "args": ["run", "/path/to/kite-mcp/src/index.ts"]
    }
  }
}

Development

Build (Optional)

bun run build

Development Mode

bun run dev          # Watch mode for MCP server
bun run dev:auth     # Watch mode for auth server

Architecture

The project follows the Single Responsibility Principle:

• ConfigManager: Environment and configuration handling
• TokenManager: Token persistence and validation
• OAuthServer: OAuth 2.0 authentication flow
• KiteClient: Kite API wrapper with error handling
• KiteMCPServer: MCP protocol implementation
• Tools: Individual MCP tool implementations

Environment Variables

API_KEY=your_kite_api_key        # Required: Kite Connect API Key
API_SECRET=your_kite_api_secret  # Required: Kite Connect API Secret
OAUTH_PORT=50000                 # Optional: OAuth server port (default: 50000)

Security

• Tokens are stored locally in access_token.json
• OAuth flow uses secure redirect handling
• API credentials are never logged or exposed
• Tokens auto-expire for security

Troubleshooting

Authentication Issues

1. Verify API credentials in .env
2. Check redirect URL in Kite Connect app settings
3. Ensure OAuth port (50000) is available

Token Expiry

• Kite tokens expire every ~6 hours
• Re-run bun run auth when expired
• Server will notify you of authentication status

MCP Connection Issues

1. Verify Claude Desktop configuration
2. Check server is running: bun start
3. Look for errors in Claude Desktop logs
