Prerequisites

• Python

• Zerodha trading account with Personal API access from here

• Zerodha API key and secret

• Gemini API key or Application Default Credentials (for Google ADK Agent)

Installation

1. Clone the repository:

git clone https://github.com/jainsourabh2/zerodha-mcp.git
cd zerodha-mcp

2. Create and activate a virtual environment:

python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

3. Install dependencies:

pip3 install -r requirements.txt

4. Set up environment variables:

# Copy the example environment file
cp .env.example .env

# Edit the .env file with your credentials

5. Create a .env file with your configuration:

# Server Configuration
ZERODHA_API_KEY=your_api_key
ZERODHA_API_SECRET=your_api_secret
PORT=8001
SERVER_MODE=sse  # or stdio

# Client Configuration
MCP_HOST=localhost
MCP_PORT=8001
GOOGLE_API_KEY=your_google_api_key

Server Usage

The server provides a set of tools for interacting with the Zerodha trading platform. To start the server:

1. Make sure your .env file is properly configured with your Zerodha API credentials.

2. Start the server using one of the following methods:

# Using environment variables
python server.py

# Or using command line arguments
python server.py --api-key your_api_key --api-secret your_api_secret --port 8001 --mode sse

The server provides the following tools:

• get_login_url: Get the login URL for user authentication

• get_access_token: Generate access token using request token

• get_user_profile: Get user's Zerodha profile information

• get_margins: Get available margins and fund details

• get_holdings: Get portfolio holdings

• get_positions: Get current positions

• get_orders: Get all orders for the day

• get_order_history: Get history of a specific order

• get_order_trades: Get trades generated by an order

• place_order: Place a new order

• modify_order: Modify an existing order

• cancel_order: Cancel an order

Client Usage

This project provides three client implementations:

1. Using Google ADK (client/google_adk_client.py)

All clients connect to the MCP server and provide an interactive interface for trading operations.

### Running the Google ADK Client

1. Ensure you have authenticated with Google AI, either by setting the `GOOGLE_API_KEY` environment variable (and uncommenting it in `.env`) or by using Application Default Credentials (run `gcloud auth application-default login`).
2. Start the client using one of the following methods:

```bash
# Using environment variables from .env file
python client/google_adk_client.py

# Using command line arguments
python client/google_adk_client.py --host localhost --port 8001

# Using a combination (command line arguments take precedence)
MCP_HOST=localhost MCP_PORT=8001 python client/google_adk_client.py --host otherhost --port 9000

Client Configuration

Both clients support configuration through multiple sources, with the following precedence:

1. Command-line arguments (highest precedence)

2. Environment variables

3. .env file variables

Configuration options:

• Environment variables: MCP_HOST and MCP_PORT

• Command-line arguments: --host and --port

• .env file variables: MCP_HOST, MCP_PORT, OPENAI_API_KEY, and GOOGLE_API_KEY

Default values (if no configuration is provided):

• Host: localhost

• Port: 8001

The client automatically loads environment variables from the .env file in the project root directory. Make sure your .env file contains the necessary configuration:

# Client Configuration
MCP_HOST=localhost
MCP_PORT=8001
OPENAI_API_KEY=your_openai_api_key
# GOOGLE_API_KEY=your_google_api_key

3. The client will automatically connect to the MCP server using the provided configuration.

4. Once connected, you can interact with the assistant using natural language commands. For example:

   • "Show me my portfolio holdings"

   • "What are my current positions?"

   • "Place a market order for 10 shares of RELIANCE"

   • "Cancel order ID 123456"

5. To exit the client, type 'quit' when prompted.
