The primary manifest — the file an agent reads to learn what this artifact does.
The official Helius AI tooling repository — everything you need to interact with Helius and Solana from the command line, from AI assistants like Claude, or autonomously as an agent.
| Package | Description | Install |
|---|---|---|
helius-cli | CLI for managing Helius accounts and querying Solana data | npm install -g helius-cli |
helius-mcp | MCP server with 10 public tools total: 9 routed domains plus expandResult | claude mcp add helius npx helius-mcp@latest |
helius-skills | Standalone Claude Code skills for building on Solana | ./install.sh |
helius-plugin | Claude Code plugin — bundles all skills and auto-starts the MCP server | /plugin install helius@claude-community |
helius-cursor | Cursor plugin — live blockchain tools and expert coding patterns | /add-plugin → search "Helius" |
A CLI built for developers and LLM agents to manage Helius accounts, query Solana blockchain data, and automate workflows.
npm install -g helius-cli
# or
pnpm add -g helius-cli#### Existing Helius users
If you already have an API key, just set it and go:
helius config set-api-key <your-api-key>Get your key from dashboard.helius.dev. That's it — skip the steps below.
#### New users — create an account
Step 1 — Generate a keypair
helius keygenThis creates a new Solana keypair and saves it to ~/.helius/keypair.json. The public key is printed to the terminal — you'll need it for the next step.
Step 2 — Fund the keypair (only for autopay)
Skip this step if you'll pay through the hosted payment link (the default). For autopay (--pay), send the following to the public key from step 1:
You can use any wallet or exchange to send funds.
Step 3 — Create your Helius account
Every new account needs an email, first name and last name. The wallet is only used to pay.
# Default: prints a hosted payment link; pay with any wallet, then finalize
helius signup --email [email protected] --first-name Jane --last-name Doe
helius signup --resume
# Or autopay from the funded keypair
helius signup --pay --email [email protected] --first-name Jane --last-name DoeStep 4 — Start using the CLI
# Query a wallet balance
helius balance <wallet-address>
# Parse a transaction
helius tx parse <signature>Account & Auth — Generate keypairs, create and upgrade Helius accounts, manage projects and API keys
Blockchain Queries — SOL and token balances, transaction parsing and history, digital assets (NFTs) via the DAS API, account info, block data, network status, and priority fee estimation
Webhooks — Create, update, and delete webhooks for transaction monitoring
Real-time Streaming — WebSocket subscriptions for accounts, logs, slots, signatures, and programs
Staking — Create and manage stake accounts, stake and unstake transactions
ZK Compression — 24+ commands for working with compressed accounts and tokens
Transaction Sending — Use Helius Sender for low-latency sends
The CLI stores configuration at ~/.helius/config.json. API keys are resolved in this order:
--api-key <key> flagHELIUS_API_KEY environment variable~/.helius/config.jsonhelius config show # View current config
helius config set-api-key <key> # Set API key
helius config set-network devnet # Switch to devnet
helius config clear # Reset configA Model Context Protocol server that exposes Helius and Solana tools directly to AI assistants. Once connected, Claude and other MCP-compatible models can query blockchain data, manage webhooks, and send transactions without any additional code.
Note on the Helius docs MCP: The Helius docs site at helius.dev/docs exposes a separate MCP server auto-generated by Mintlify. That server is scoped only to documentation search and is not related to this repo. helius-mcp here is the comprehensive server covering all Helius and Solana functionality.The server exposes 10 public tools total: 9 routed domain tools plus expandResult.
heliusAccount — account setup, auth, plans, billingheliusWallet — wallet balances, holdings, identity, wallet historyheliusAsset — assets, NFTs, collections, token holdersheliusTransaction — parsed transactions and wallet transaction historyheliusChain — raw chain state, token accounts, blocks, network status, stake reads, priority fees, transaction simulationheliusStreaming — webhook CRUD and live subscription configurationheliusKnowledge — docs, guides, pricing references, troubleshooting, source, blog, SIMDsheliusWrite — SOL/token transfers and staking mutationsheliusCompression — compressed account, proof, balance, and history queriesexpandResult — expand summary-first results by resultIdThe 9 domain tools take a Helius action name in action, for example heliusWallet + getBalance or heliusStreaming + createWebhook. Heavy responses are summary-first; use expandResult to fetch a full section, range, page, or continuation on demand.

claude mcp add helius node $(pwd)/dist/index.jsStandalone Claude Code skills that turn Claude into a domain expert. Each skill is a self-contained directory with a SKILL.md and reference files — install once, invoke with /skill-name in any Claude Code session.
| Skill | Invoke | Description |
|---|---|---|
helius | /helius | Build Solana apps with Helius infrastructure — Sender, DAS API, WebSockets, Laserstream, webhooks, priority fees, and our Wallet API |
helius-dflow | /helius-dflow | Build Solana trading apps combining DFlow's trading APIs (spot swaps, prediction markets, Proof KYC) with Helius infrastructure |
helius-jupiter | /helius-jupiter | Build Solana DeFi apps combining Jupiter's APIs with Helius infrastructure — swaps, lending, limit orders, DCA, perps, and price data |
helius-okx | /helius-okx | Compose OKX DEX aggregation and market data with Helius Solana infrastructure — swaps, token discovery, smart money signals, and portfolio intelligence |
helius-phantom | /helius-phantom | Build browser-based Solana apps with Phantom wallet + Helius — wallet connection, transaction signing, API key proxying, and secure URLs |
svm | /svm | Explore Solana's architecture and protocol internals — SVM execution engine, account model, consensus, validator economics, and token extensions |
Each skill has its own install.sh. Clone this repo and run the installer for whichever skills you want:
git clone https://github.com/helius-labs/core-ai.git
cd core-ai
# Install individual skills
./helius-skills/helius/install.sh # Helius skill
./helius-skills/svm/install.sh # SVM architecture skillBy default, skills install to ~/.claude/skills/ (personal, available in all projects). Use --project to install to .claude/skills/ in your current project instead:
./helius-skills/helius/install.sh --projectAll skills except svm require a Helius API key. The svm skill uses public knowledge tools only. Add the MCP server before using any skill:
claude mcp add helius npx helius-mcp@latestAn all-in-one Claude Code plugin that bundles all skills and auto-starts the MCP server. The easiest way to get everything set up in one step.
/plugin marketplace add anthropics/claude-plugins-community
/plugin install helius@claude-communityOr install directly from source:
/plugin marketplace add helius-labs/core-ai
/plugin install helius@helius-labsHelius MCP Server — auto-starts with the plugin. Exposes 10 public tools total: 9 routed domain tools plus expandResult. Domain tools take Helius action names via action, and heavy responses are summary-first.

The plugin auto-starts the MCP server, but you still need a Helius API key. On first use, Claude will guide you through one of these paths:
setHeliusApiKey tool with your key from https://dashboard.helius.devgenerateKeypair → signup with mode: "link" (browser pay) or mode: "autopay" (pay USDC from local keypair) → after browser payment, signup with mode: "resume"npx helius-cli@latest keygen → npx helius-cli@latest signup --plan agent (link) → user pays in browser → npx helius-cli@latest signup --resume (or --pay to autopay)claude --plugin-dir ./helius-pluginHelius skills are model-agnostic — they work across Claude Code, Codex CLI, OpenAI API, Claude API, Cursor, and other AI tools.
