E*TRADE MCP Server

A Model Context Protocol (MCP) server for E*TRADE's Market API, built with FastMCP.

Features

This MCP server provides access to E*TRADE's Market API endpoints:

Installation

1. Clone this repository

2. Install dependencies:

pip install -e .

3. Copy .env.example to .env and add your E*TRADE API credentials:

cp .env.example .env

4. Edit .env and add your credentials:

ETRADE_CONSUMER_KEY=your_consumer_key_here
ETRADE_CONSUMER_SECRET=your_consumer_secret_here
ETRADE_ENVIRONMENT=sandbox  # or 'production'

Getting E*TRADE API Credentials

1. Go to E*TRADE Developer Portal

2. Sign up or log in with your E*TRADE account

3. Request a Sandbox consumer key at https://us.etrade.com/etx/ris/apikey

4. Get your Consumer Key and Consumer Secret

5. Start with the sandbox environment for testing

Authentication

One-time Setup (Recommended)

Run the authentication script to get and save your access tokens:

python authenticate.py

This will:

1. Prompt you to visit an E*TRADE authorization URL

2. Ask you to enter the verification code

3. Save the access tokens to your .env file

The MCP server will automatically use these saved tokens.

Note: Access tokens expire at midnight US Eastern time, so you'll need to re-authenticate daily.

Alternative: Manual Authentication

You can also authenticate through the MCP tools:

1. Call etrade_get_auth_url() to get the authorization URL

2. Visit the URL in your browser and authorize the application

3. Copy the verification code

4. Call etrade_authenticate(verifier="YOUR_CODE") with the verification code

Usage

Running the Server

The server runs as an HTTP server on port 8000 with the MCP endpoint at /mcp:

etrade-mcp

Or with Python:

python -m etrade_mcp.server

The server will start at http://localhost:8000 with the MCP endpoint available at http://localhost:8000/mcp.

Connecting to the Server

Configure your MCP client to connect to the HTTP endpoint:

{
  "mcpServers": {
    "etrade": {
      "url": "http://localhost:8000/mcp"
    }
  }
}
