LongPort OpenAPI – multi-language SDK (Rust, Python, Node.js, Java, C/C++, Go) plus an MCP server implementation to access LongPort trading/quote/portfolio and real-time subscription APIs.
https://github.com/longportapp/openapiStop context-switching between your development environment and trading platforms. This MCP server puts real-time market data, portfolio positions, and trading capabilities directly into your AI workflow.
You're building financial applications, but your AI assistant is blind to market reality. Need to check AAPL's current price? Switch to a browser. Verify your portfolio positions? Open another app. Place a test order? Fire up your trading platform.
This constant context switching kills productivity when you're trying to build, test, or analyze anything finance-related.
The LongPort MCP server bridges this gap by exposing comprehensive trading and market data APIs directly to your MCP-compatible AI tools. Now your AI assistant can:
Instant Market Context: Ask "What's TSLA trading at?" and get real-time pricing data without opening a browser or trading app.
Portfolio Debugging: When your trading algorithm acts up, query positions and recent orders directly through your AI assistant to understand what happened.
Rapid Strategy Testing: Test trading logic by placing small orders and immediately checking execution status, all within your development conversation.
Market Research Integration: Pull historical data for any symbol while discussing strategy ideas with your AI assistant.
Algorithmic Trading Development: Debug your trading bot by querying real positions and order history when something goes wrong. "Show me all AAPL orders from today" reveals exactly what your algorithm did.
Financial Dashboard Building: Pull live portfolio data and market quotes to populate your custom dashboards without writing separate API integration code.
Risk Management: Monitor real-time positions and account balances while developing risk management rules. Your AI can help analyze current exposure while having access to live data.
Market Analysis Workflows: Research stocks by combining AI analysis with real-time market data. Ask for fundamental analysis while simultaneously pulling current trading volumes and price movements.
Strategy Backtesting: Access historical market data for any symbol while discussing strategy ideas, letting your AI assistant help validate concepts against real market behavior.
The MCP server handles all the complexity of LongPort's authentication, rate limiting, and WebSocket connections. Just configure your credentials:
export LONGPORT_APP_KEY=your_app_key
export LONGPORT_APP_SECRET=your_app_secret
export LONGPORT_ACCESS_TOKEN=your_access_token
Then connect through any MCP-compatible client. The server exposes clean, focused tools for the most common financial data operations without the complexity of managing SDK installations across multiple languages.
This isn't a toy implementation. It's built on LongPort's production OpenAPI infrastructure that powers real trading applications across 7 programming languages. The same WebSocket connections, authentication systems, and rate limiting that handle serious trading volume.
The MCP server gives you a lightweight way to access this industrial-strength financial data infrastructure without the overhead of full SDK integration.
Whether you're building quantitative strategies, financial dashboards, or just need market context in your development workflow, this MCP server eliminates the friction between your AI tools and real financial data.
No more tab switching. No more manual data lookups. Just natural conversation with your AI assistant that has complete access to your trading account and real-time market information.
