Real-Time Crypto Market Data MCP for OKX with WebSocket Support

The world of cryptocurrency trading moves at lightning speed. To stay ahead, traders and developers need instant access to accurate market data—price movements, candlestick patterns, and live updates—delivered in real time. The OKX MCP Server is a powerful solution designed to bridge the gap between AI-driven workflows and live crypto market intelligence. By leveraging the Model Context Protocol (MCP), this server enables seamless integration of real-time and historical data from OKX, one of the leading global cryptocurrency exchanges.

Whether you're building a trading bot, conducting technical analysis, or integrating market insights into an AI assistant, the OKX MCP Server delivers the tools you need with precision and efficiency.

What Is the OKX MCP Server?

The OKX MCP Server is a Node.js-based service that connects to OKX’s public APIs to retrieve real-time cryptocurrency market data. It supports both one-time data queries and continuous live updates through WebSocket subscriptions. Built with developer flexibility in mind, it's especially useful for AI agents like Claude that require contextual, up-to-the-minute financial data.

Key capabilities include:

Fetching current prices for any supported trading pair
Retrieving historical candlestick data (OHLC) across multiple timeframes
Subscribing to live ticker streams for real-time price monitoring
Visualizing data in multiple formats: Markdown, ASCII charts, and tables

Because it uses public API endpoints, no authentication or API keys are required—making setup fast and secure.

Core Features & Benefits

Key Features

The OKX MCP Server offers a robust set of functions tailored for real-time market interaction:

get_price: Instantly retrieve the latest price for a given symbol (e.g., BTC-USDT)
get_candlesticks: Pull historical OHLC (Open, High, Low, Close) data over customizable intervals (1m, 5m, 1h, etc.)
subscribe_ticker: Establish a persistent WebSocket connection for live price updates
get_live_ticker: Access the most recent ticker snapshot on demand
unsubscribe_ticker: Cleanly terminate active subscriptions to manage resource usage

These methods are designed for low-latency performance and high reliability, ensuring timely delivery of critical trading signals.

Notable Benefits

✅ Real-time market access: Stay synchronized with fast-moving crypto markets
✅ Flexible visualization: Render candlesticks as ASCII art, Markdown tables, or JSON for easy parsing
✅ WebSocket-powered updates: Receive push-based notifications instead of polling
✅ No API keys needed: Leverages public OKX endpoints for frictionless deployment
✅ AI-ready integration: Works natively with MCP-compatible assistants like Claude

This combination makes the server ideal for prototyping, automation, and production-grade applications alike.

Practical Use Cases

1. Live Price Monitoring

Traders can use subscribe_ticker to track bid/ask spreads and last traded prices across major pairs like ETH-USDT or SOL-BTC in real time—directly within their AI chat interface.

2. Historical Trend Analysis

Using get_candlesticks, analysts can pull weeks’ worth of 1-hour candles to identify support/resistance levels or backtest trading strategies.

3. Automated Price Alerts

Set up conditional logic in your application: if BTC drops below $60,000, trigger an alert. The server provides the data layer; your system handles the decision-making.

4. Volatility Visualization

Generate ASCII chart previews of recent price action to quickly assess market sentiment without leaving your terminal or chat environment.

5. AI-Powered Research Assistants

Integrate the server with an LLM-powered research agent that answers questions like “Has BNB been bullish over the past 24 hours?” by fetching and interpreting actual market data.
