Prerequisites

• Python 3.10 or higher

• DhanHQ account with API access

• DhanHQ Client ID and Access Token

Installation

Option 1: Install from PyPI (when published)

pip install dhan-mcp-server

Option 2: Install from source

git clone https://github.com/Vedhasagaran/dhan-mcp-py.git
cd dhan-mcp-py
pip install -e .

Option 3: Direct installation from GitHub

pip install git+https://github.com/Vedhasagaran/dhan-mcp-py.git

Configuration

1. Set Environment Variables

The server requires DhanHQ credentials to be set as environment variables:

Windows (PowerShell):

$env:DHAN_CLIENT_ID="your_client_id"
$env:DHAN_ACCESS_TOKEN="your_access_token"

Windows (Command Prompt):

set DHAN_CLIENT_ID=your_client_id
set DHAN_ACCESS_TOKEN=your_access_token

Linux/Mac:

export DHAN_CLIENT_ID="your_client_id"
export DHAN_ACCESS_TOKEN="your_access_token"

Using .env file (recommended):

Create a .env file in your project directory:

DHAN_CLIENT_ID=your_client_id
DHAN_ACCESS_TOKEN=your_access_token

2. Configure MCP Client

Add the server to your MCP client configuration. The configuration file location varies by application:

• Claude Desktop: %APPDATA%\Claude\claude_desktop_config.json (Windows) or ~/Library/Application Support/Claude/claude_desktop_config.json (Mac)

• Other MCP Clients: Refer to your client's documentation

Example configuration:

{
  "mcpServers": {
    "dhan": {
      "command": "dhan-mcp-server",
      "env": {
        "DHAN_CLIENT_ID": "your_client_id",
        "DHAN_ACCESS_TOKEN": "your_access_token"
      }
    }
  }
}

Alternative using Python directly:

{
  "mcpServers": {
    "dhan": {
      "command": "python",
      "args": ["-m", "server"],
      "env": {
        "DHAN_CLIENT_ID": "your_client_id",
        "DHAN_ACCESS_TOKEN": "your_access_token"
      }
    }
  }
}

Usage

Starting the Server Manually

If you want to run the server directly:

dhan-mcp-server

Or with Python:

python -m server

The server communicates via stdio (standard input/output) using the MCP protocol.

Available Tools

Once connected via an MCP client, the following tools are available:

get_holdings_summary

Fetches your current holdings from DhanHQ.

Returns:

{
  "holdings": [
    // Array of holding objects
  ]
}

get_all_orders

Fetches all orders from your DhanHQ account.

Returns:

{
  "orders": [
    // Array of order objects with details like order ID, status, quantity, price, etc.
  ]
}

get_trade_history

Fetch trade history within a specific date range.

Parameters:

• from_date: Start date in format YYYY-MM-DD (e.g., 2025-11-01)

• to_date: End date in format YYYY-MM-DD (e.g., 2025-11-21)

Returns:

{
  "status": "success",
  "from_date": "2025-11-01",
  "to_date": "2025-11-21",
  "trades": [
    // Array of trade objects with details like trade ID, order ID, quantity, price, time, settlement status
  ]
}

renew_access_token

Renews your DhanHQ access token for another 24 hours. This is useful for extending your session without manually copying tokens from the web interface.

Important: Only works with tokens generated from Dhan Web (web.dhan.co). Tokens obtained via API key/secret cannot be renewed using this method.

Returns:

{
  "status": "success",
  "message": "Token renewed successfully...",
  "new_token": "eyJ0eXAiOiJKV1QiLCJhbGc...",
  "expires_in": "24 hours"
}

Usage: After renewal, update your DHAN_ACCESS_TOKEN environment variable with the new token, or update your MCP client configuration.

Development

Setting Up Development Environment

# Clone the repository
git clone https://github.com/Vedhasagaran/dhan-mcp-py.git
cd dhan-mcp-py

# Create virtual environment
python -m venv venv

# Activate virtual environment
# Windows:
venv\Scripts\activate
# Linux/Mac:
source venv/bin/activate

# Install in editable mode with dependencies
pip install -e .

Adding New Tools

To add new DhanHQ API endpoints:

1. Add a new function in server.py decorated with @mcp.tool()

2. Follow this pattern:

@mcp.tool()
def your_new_tool() -> dict:
    """
    Description of what this tool does.
    """
    client = dhanhq(client_id, access_token)
    result = client.your_api_method()
    return {"data": result}

Security Notes

• Never commit credentials: The .gitignore file excludes .env files

• Keep tokens secure: Access tokens provide full access to your DhanHQ account

• Use environment variables: Always load credentials from environment variables

• Rotate tokens regularly: Follow DhanHQ's security best practices

Troubleshooting

"Missing DHAN_CLIENT_ID or DHAN_ACCESS_TOKEN"

Ensure environment variables are set correctly. Check with:

# Windows PowerShell
echo $env:DHAN_CLIENT_ID

# Linux/Mac
echo $DHAN_CLIENT_ID

MCP Client Can't Find Server

Verify the installation:

pip show dhan-mcp-server
which dhan-mcp-server  # Linux/Mac
where dhan-mcp-server  # Windows
