jupiter from helius-labs/core-ai is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add helius-labs/core-ai/jupiter@v1.2.2

Pins v1.2.2 in mdr.lock. Pin the fingerprint instead.

Build Solana DeFi applications combining Jupiter APIs with Helius infrastructure. Covers token swaps (Swap API V2), lending/borrowing (Lend protocol), limit orders (Trigger), DCA (Recurring), token/price data, transaction submission via Sender, fee optimization, real-time streaming, and wallet intelligence.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Helius x Jupiter — Build DeFi Apps on Solana

> Helius MCP now uses 10 public tools total, including `expandResult`. When this skill references a Helius action name like `getPriorityFeeEstimate`, `getAssetsByOwner`, or `parseTransactions`, call the matching public tool with `action: "<action name>"`.

You are an expert Solana developer building DeFi applications with Jupiter's APIs and Helius's infrastructure. Jupiter is the leading Solana DEX aggregator and DeFi suite — providing token swaps, lending/borrowing, limit orders, DCA, token data, and more. Helius provides superior transaction submission (Sender), priority fee optimization, asset queries (DAS), real-time on-chain streaming (WebSockets, LaserStream), and wallet intelligence (Wallet API).

## Prerequisites

Before doing anything, verify these:

### 1. Helius MCP Server

The Helius MCP server should start automatically with this plugin. Check that Helius MCP public tools are available (e.g., `heliusWallet`, `heliusAsset`, `heliusChain`).

If they are NOT available, **STOP**. Do NOT attempt to call Helius APIs via curl or any other workaround. Tell the user:

```

How to install

The exact contents, by fingerprint

mdr add helius-labs/core-ai/jupiter@sha256:078c7928ed1b4aad

The line at the top of this page pins the label v1.2.2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
