Webull MCP Server
Webull MCP Server enables AI assistants (Cursor, Claude Desktop, Kiro, etc.) to securely access Webull OpenAPI trading and market data capabilities via the Model Context Protocol (MCP).
Source code: webull-inc/webull-openapi-mcp
What is Webull MCP
Webull MCP Server is a server built on the Model Context Protocol that wraps Webull OpenAPI capabilities into tools callable by AI assistants. With MCP, you can use natural language in your AI coding assistant to:
- Query real-time market data
- View account balances and positions
- Place, modify, and cancel orders
- Query order history and order details
Architecture Overview
Prerequisites
API Credentials (App Key and App Secret)
- Production
- Sandbox (Test)
Apply based on your account type:
Individual users: Individual Application Guide
Institutional users: Institution Application Guide
No application required. Use the publicly shared test credentials to get started immediately. See SDKs and Tools.
Other Requirements
- Market Data Subscription (if market data is needed): webullapp.com/quote | Subscription Guide
- uvx (Python 3.10+ required) — uv Installation Guide
- MCP-compatible AI Client — e.g. Cursor, Claude Desktop, Kiro
Setup Steps
Step 1: Install
Ensure Python 3.10+ and uvx are installed. No need to manually install Webull MCP Server — your AI client will automatically download and launch it via uvx.
Step 2: Configure AI Client
Add the following configuration to your AI client's MCP config file. Replace your_app_key and your_app_secret with the credentials obtained in the prerequisites:
- Cursor
- Claude Desktop
- Kiro
Edit .cursor/mcp.json:
{
"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"
}
}
}
}
Edit claude_desktop_config.json:
{
"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"
}
}
}
}
Edit .kiro/settings/mcp.json:
{
"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"
}
}
}
}
For sandbox environment, set WEBULL_ENVIRONMENT to uat.
Step 3: Authenticate
This step is only required if your account has Two-Factor Authentication enabled.
Complete a one-time authentication in the terminal before first use:
uvx webull-openapi-mcp auth
Authentication flow:
After approving the request in the Webull App, the token is saved locally. The token is valid for 15 days and auto-refreshes on use.
Step 4: Verify Connection
Restart your AI client and try the following in a conversation:
Get my account list
If your account information is returned, Webull MCP is successfully connected.

Security Recommendations
- Never share your App Key, App Secret, or Token via chat with an AI model. These credentials should only be passed to the MCP Server process via the
envfield inmcp.json, never as conversation content. - Use
preview_stock_order/preview_option_orderbefore placing orders. - Use
WEBULL_SYMBOL_WHITELISTto restrict tradable symbols.
