Jupiter MCP Server

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

Features

• Execute swaps via Jupiter's Ultra API, handling slippage, priority fees, and transaction landing.

Prerequisites

• 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).
