jupiter-mcp

An MCP server for executing token swaps on the Solana blockchain using Jupiter's new Ultra API.

• Fetch swap orders from Jupiter's Ultra API, combining DEX routing and RFQ (Request for Quote) for optimal pricing.
• Execute swaps via Jupiter's Ultra API, handling slippage, priority fees, and transaction landing.

• Node.js: Version 18 or higher (for native fetch support).
• Solana Wallet: A private key (base58-encoded) for signing transactions.
• RPC Endpoint: Access to a Solana RPC node (e.g., https://api.mainnet-beta.solana.com).
