kite-mcp

MCP server for Zerodha Kite -- trade Indian stocks through natural conversation with any MCP-compatible AI assistant.

Why an MCP server instead of a Python library?

Traditional Kite wrappers require you to write Python code to trade. With kite-mcp, you just talk:

You:       "Buy 50 Reliance at market price"
Assistant: checks quote, verifies funds, asks for confirmation, places order

You:       "How's my portfolio doing?"
Assistant: fetches holdings, calculates P&L, summarizes gainers and losers

You:       "Set a stop-loss on my HAL position at 3400"
Assistant: places a GTT trigger for you

No code. No scripts. No terminal. Just conversation.

kite-mcp connects any MCP-compatible AI assistant directly to your Zerodha account with 14 trading tools, automated TOTP login, and auto-retry on expired tokens.

How it works

You (natural language) --> AI Assistant --> kite-mcp (MCP server) --> Zerodha Kite API

Your AI assistant interprets your intent, maps stock names to symbols (e.g., "Infosys" to NSE:INFY), checks your funds, and executes trades -- all through the MCP protocol. The server handles authentication automatically, including daily token refresh via TOTP.

Quick Start

1. Install

pip install kite-mcp

2. Get your credentials

You need a Kite Connect API app. From your app dashboard, note your API Key and API Secret.

You also need:

• User ID -- your Zerodha client ID (e.g., AB1234)
• Password -- your Zerodha login password
• TOTP Secret (recommended) -- the base32 seed from setting up an external authenticator app for Zerodha 2FA. This enables fully automated login with no manual steps.

How to get your TOTP secret

1. Log in to console.zerodha.com
2. Go to My Profile > Security > 2FA Settings
3. Switch to an external authenticator app (Google Authenticator, Authy, etc.)
4. When the QR code appears, look for a "Can't scan? Copy this key" link
5. That key is your TOTP secret -- save it before completing setup
6. Enter the 6-digit code from your authenticator to finish

3. Configure your MCP client

Add this to your MCP client configuration. The config location depends on your client -- refer to your client's documentation for the exact path.

{
  "mcpServers": {
    "kite": {
      "command": "kite-mcp",
      "env": {
        "KITE_API_KEY": "your-api-key",
        "KITE_API_SECRET": "your-api-secret",
        "KITE_USER_ID": "your-user-id",
        "KITE_PASSWORD": "your-password",
        "KITE_TOTP_SECRET": "your-totp-secret"
      }
    }
  }
}

Restart your MCP client. You're ready to trade.

4. Try it out

Open a new chat and try:

• "Show my portfolio holdings"
• "What's Tata Motors trading at?"
• "Buy 10 Infosys at market price"
• "How much cash do I have available?"
• "Cancel my last pending order"
• "Show my top gainers and losers"

The AI assistant understands stock names in plain English -- no need to use trading symbols.

Environment Variables

Variable	Required	Description
KITE_API_KEY	Yes	Kite Connect API key
KITE_API_SECRET	Yes	Kite Connect API secret
KITE_USER_ID	Yes	Zerodha client ID
KITE_PASSWORD	Yes	Zerodha login password
KITE_TOTP_SECRET	No	TOTP base32 seed for auto-login. Without this, you must run kite-mcp-login manually each day.

Manual Login

If you don't have a TOTP secret, you can log in manually each day:

export KITE_API_KEY=your-api-key
export KITE_API_SECRET=your-api-secret
export KITE_USER_ID=your-user-id
export KITE_PASSWORD=your-password
kite-mcp-login

This caches the access token for the rest of the day. The MCP server will use the cached token until it expires.

Use Cases

• Quick trades -- "Buy 50 Reliance" / "Sell all my Yes Bank"
• Research + action -- "What's the 52-week high of HDFC Bank? Should I add more at current levels?"
• Risk management -- "Set a stop-loss GTT on my BDL position at 1100"
• Scheduled reports -- Combine with MCP scheduled tasks to get a daily portfolio summary at 9am
• Slack integration -- Pair with Slack MCP to receive portfolio alerts in your Slack channel
