What is helius-jupiter?

A coding guide for building Solana DeFi applications with Helius and Jupiter, a service that combines token swaps with lending, trading orders, token data, and other financial tools.

Use it for swap interfaces, trading terminals, lending or borrowing, limit orders, recurring purchases, token safety checks, and transaction submission.

It helps an agent work with the separate services and their APIs when building blockchain trading features.

SkillSpector: 1 finding, up to medium

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

medium Agent Snooping · line 1
Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.

Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.04843
Opus 5	$0.00000	$0.02422
Sonnet 5	$0.00000	$0.00969
Haiku 4.5	$0.00000	$0.00484

Security

Grade A, and why

helius-jupiter scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

**CRITICAL**: Check if 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.

name: helius-jupiter version: "1.2.0" description: > Build Solana DeFi applications combining Jupiter APIs with Helius infrastructure. Use this skill when: building token swap UIs or trading terminals, integrating lending/borrowing via Jupiter Lend, setting up limit orders or DCA, querying token prices and metadata, checking token safety via Token Shield, embedding a drop-in swap widget, submitting transactions via Helius Sender, or optimizing priority fees for DeFi operations. Requires helius-mcp MCP server.

Helius x Jupiter — Build DeFi Apps on Solana

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).

MCP Router Surface

Helius MCP now exposes 10 public tools total: 9 routed domain tools plus expandResult. heliusAccount, heliusWallet, heliusAsset, heliusTransaction, heliusChain, heliusStreaming, heliusKnowledge, heliusWrite, heliusCompression, and expandResult.

This skill still names Helius action names such as getPriorityFeeEstimate, getAssetsByOwner, or parseTransactions. Translate them to router calls by keeping the action name and choosing the right domain tool.

Examples:

heliusChain({ action: "getPriorityFeeEstimate", accountKeys: ["..."] })
heliusAsset({ action: "getAssetsByOwner", ownerAddress: "..." })
heliusTransaction({ action: "parseTransactions", transactions: ["..."] })

Prerequisites

Before doing anything, verify these:

1. Helius MCP Server

CRITICAL: Check if 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:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
