OKX-DEX-SDK MCP SSE Server

OKX-DEX-SDK MCP SSE SERVER EXAMPLE

This is an example implementation of an SSE (Server-Sent Events) MCP server that leverages @okx-dex/okx-dex-sdk to support DEX trading and cross-chain bridge operations.

🚀 Features

DEX API

Built for the Solana blockchain, the DEX API supports:

Executing swap trades
Generating swap instructions
Fetching price quotes
Retrieving supported tokens and liquidity pool (LP) data

Bridge API

Enables cross-chain functionality, including:

Fetching supported bridgeable tokens and chains
Performing cross-chain bridge transactions
Retrieving cross-chain price quotes

📦 Installation

git clone https://github.com/0xobedient/okx-mcp
cd okx-mcp
pnpm install
pnpm run dev

🔐 Environment Variables

Create a .env file at the root of the project using .env.example as a template:

OKX_API_KEY=              # Your OKX API key
OKX_API_SECRET=           # Your OKX API secret
OKX_PASSPHRASE=           # Your OKX API passphrase
OKX_PROJECT_ID=           # Your OKX project ID (if required)
RPC_ENDPOINT_URI=         # RPC endpoint URI for Solana or target blockchain
WALLET_PRIVATE_KEY=       # Private key for the wallet used in trades
PORT=3000                 # Port number for the SSE server

📦 Dependency

This MCP server is entirely built upon the official OKX SDK:

@okx-dex/okx-dex-sdk – the core SDK providing access to OKX DEX trading and bridge functionalities.

This server cannot be installed
