About kukapay/jupiter-mcp

An MCP server that enables token swaps on the Solana blockchain using Jupiter's new Ultra API. It combines DEX routing and RFQ (Request for Quote) to achieve optimal pricing for swaps. The server provides two core tools: get-ultra-order to fetch a swap order with pricing and transaction data, and execute-ultra-order to execute the swap transaction, handling slippage, priority fees, and transaction landing. Requires Node.js 18+, a Solana wallet private key, and an RPC endpoint. Installation involves cloning the repository and installing dependencies via npm. Configured through an MCP client with environment variables SOLANA_RPC_URL and PRIVATE_KEY.
