Overview
Jupiter MCP Server is an MCP server that orchestrates token swap operations on Solana by interfacing with Jupiter’s Ultra API. It fetches swap orders by combining DEX routing and RFQ for optimal pricing, then constructs and signs transactions via a Solana wallet private key and a configured RPC endpoint. The server executes swaps through Jupiter’s Ultra API, handling slippage tolerance, priority fees, and transaction landing to maximize profitability and reliability. The system exposes Ultra API tools: get-ultra-order, which returns a signed transaction payload and pricing data; and execute-ultra-order, which submits the prepared transaction and returns status, transactionId, slot, and swap results. The README also shows an example configuration for the MCP client, including a mcpServers map with command, args, and environment variables SOLANA_RPC_URL and PRIVATE_KEY. Prerequisites include Node.js 18+ for native fetch, a Solana private key, and access to a Solana RPC node (e.g., https://api.mainnet-beta.solana.com). The installation steps cover cloning, npm install, and configuring the client. This MCP server targets Solana token swaps using Jupiter Ultra API to optimize pricing and execute orders.
