Jupiter MCP Server: Ultra-Fast, Low-Cost Decentralized Swaps

Jupiter MCP Server

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

Features

• 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.

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).

Installation

1. Clone the Repository :

   git clone https://github.com/your-username/jupiter-mcp.git

cd jupiter-mcp

2. Install Dependencies : Ensure you have the MCP Server package installed along with other required dependencies:

   npm install

3. Client Configuration :

{
  "mcpServers": {
    "Jupiter-MCP": {
      "command": "node",
      "args": ["path/to/jupiter-mcp/server/index.js"],
      "env": {
