# 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**:
```bash
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:
```bash
npm install
```
3. **Client Configuration**:
```json
{
"mcpServers": {
"Jupiter-MCP": {
"command": "node",
"args": ["path/to/jupiter-mcp/server/index.js"],
"env": {
"SOLANA_RPC_URL": "solana rpc url you can access",
"PRIVATE_KEY": "your private key"
}
}
}
}
```
## Tools
### Ultra API Tools
- **`get-ultra-order`**:
- **Description**: Fetches a swap order from Jupiter's Ultra API, leveraging both DEX routing and RFQ for optimal pricing.
- **Inputs**:
- `inputMint`: Input token mint address (e.g., SOL or token pubkey).
- `outputMint`: Output token mint address (e.g., USDC or token pubkey).
- `amount`: Input amount as a string (e.g., "1.23").
- `slippageBps`: Slippage tolerance in basis points (e.g., 50 for 0.5%).
- **Output**: JSON with `requestId`, `transaction` (base64-encoded), `inputMint`, `outputMint`, `inAmount`, `outAmount`, `price`.
- **`execute-ultra-order`**:
- **Description**: Requests Jupiter to execute the swap transaction on behalf of the wallet owner, handling slippage, priority fees, and transaction landing.
- **Inputs**:
- `requestId`: Unique identifier from `get-ultra-order`.
- `transaction`: Base64-encoded transaction from `get-ultra-order`.
- **Output**: JSON with `status`, `transactionId`, `slot`, `inputAmountResult`, `outputAmountResult`, `swapEvents`.
## Example Interaction
