icici-mcp

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

Why an MCP server instead of a Python library?

Traditional Breeze Connect wrappers require you to write Python code to trade. With icici-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:       "Show me the NIFTY option chain for next expiry"
Assistant: fetches option chain data with strikes, premiums, and OI

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

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

How it works

You (natural language) --> AI Assistant --> icici-mcp (MCP server) --> ICICI Direct Breeze API

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

Features

14 tools for complete trading control:

Key capabilities:

• Fully automated login -- TOTP generated on the fly, no manual intervention

• Auto-retry on stale tokens -- re-authenticates transparently if a token expires mid-session

• Option chain data for F&O analysis

• Supports equity (cash), futures, options, margin, and BTST orders

Compatible with

Works with any MCP-compatible client, including:

Quick Start

1. Install

pip install icici-mcp
playwright install chromium

Note: The playwright install chromium step is required once for automated TOTP login. It downloads a headless Chromium browser (~90MB) used to log in to ICICI Direct automatically.

2. Get your credentials

You need an ICICI Direct API app. From your app dashboard, note your API Key and API Secret.

You also need:

• User ID -- your ICICI Direct client ID

• Password -- your ICICI Direct login password

• TOTP Secret (recommended) -- the base32 seed from setting up an external authenticator app for ICICI Direct 2FA. This enables fully automated login with no manual steps.

1. Log in to secure.icicidirect.com

2. Go to Profile > Security Settings > 2FA / TOTP Settings

3. Choose to set up an external authenticator app (Google Authenticator, Authy, etc.)

4. When the QR code appears, look for a "Can't scan? Copy this key" link or use a QR decoder to extract the secret

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": {
    "icici": {
      "command": "icici-mcp",
      "env": {
        "ICICI_API_KEY": "your-api-key",
        "ICICI_API_SECRET": "your-api-secret",
        "ICICI_USER_ID": "your-user-id",
        "ICICI_PASSWORD": "your-password",
        "ICICI_TOTP_SECRET": "your-totp-secret",
        "ICICI_SESSION_TOKEN": ""
      }
    }
  }
}

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 Reliance trading at?"

• "Buy 10 Infosys at market price"

• "How much cash do I have available?"

• "Cancel my last pending order"

• "Show me NIFTY option chain for the nearest expiry"

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

Environment Variables

Manual Login

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

Option 1: Use the CLI tool

export ICICI_API_KEY=your-api-key
export ICICI_API_SECRET=your-api-secret
export ICICI_USER_ID=your-user-id
export ICICI_PASSWORD=your-password
icici-mcp-login

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

Option 2: Set ICICI_SESSION_TOKEN directly

1. Visit https://api.icicidirect.com/apiuser/login?api_key=YOUR_API_KEY

2. Complete the login flow manually

3. Copy the apisession value from the redirect URL

4. Set it as ICICI_SESSION_TOKEN in your MCP client config

Use Cases

• Daily portfolio monitoring -- "Give me a summary of my portfolio with top gainers and losers"

• Quick trades -- "Buy 50 Reliance" / "Sell all my Yes Bank"

• F&O trading -- "Show me BANKNIFTY option chain" / "Buy 1 lot NIFTY 25000 CE"

• Research + action -- "What's the 52-week high of HDFC Bank? Should I add more at current levels?"

• Position management -- "Square off all my margin positions"

• Scheduled reports -- Combine with MCP scheduled tasks to get a daily portfolio summary at 9am
