Common questions

Is Webull OpenAPI safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.2.6) reached the registry 11 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

Prerequisites

Webull Developer Account — Register at:

API Credentials — Obtain your App Key and App Secret
Market Data Subscription — Subscribe to quotes for market data access:

Python 3.10+
uv (recommended) — Install guide

Quick Start

Step 1: Configure Credentials

Before running the server, you must configure your API credentials. Choose one of the following approaches:

Option A: MCP client configuration (recommended for production)

Add credentials via the env field in your MCP client config (Kiro, Cursor, Claude Desktop, etc.):

"mcpServers": { "webull": { "command": "uvx", "args": ["webull-openapi-mcp", "serve"], "env": { "WEBULL_APP_KEY": "your_app_key", "WEBULL_APP_SECRET": "your_app_secret", "WEBULL_REGION_ID": "us", "WEBULL_ENVIRONMENT": "prod" } } } }

Option B: .env file

# Create a .env file interactively:

uvx webull-openapi-mcp init

Or manually create .env with:

WEBULL_APP_KEY=your_app_key

WEBULL_APP_SECRET=your_app_secret

Step 2: Authenticate (2FA)

If your account requires Two-Factor Authentication, run the auth command and approve in your Webull mobile app:

uvx webull-openapi-mcp auth

Token is valid for 15 days and auto-refreshes. You only need to do this once (or when the token expires).

Step 3: Start the Server

uvx webull-openapi-mcp serve

That's it. Your AI assistant can now access Webull trading and market data.

Installation Options

Option 1: uvx (Recommended)

No installation needed. uvx downloads and runs the package directly from PyPI:

uvx webull-openapi-mcp serve

Option 2: pip

pip install webull-openapi-mcp

webull-openapi-mcp serve

Option 3: Local Development

git clone https://github.com/webull-inc/webull-openapi-mcp.git

cd webull-openapi-mcp uv sync uv run python -m webull_openapi_mcp serve

Client Configuration

Kiro / Cursor / Claude Desktop / Claude Code

Add to your MCP configuration:

Using environment variables:

Using .env file (local development):

"mcpServers": { "webull": { "command": "uv", "args": [ "run", "--directory", "/path/to/webull-openapi-mcp", "python", "-m", "webull_openapi_mcp", "serve", "--env-file", "/path/to/.env" ] } } }
