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
