helius-integration-specialist

helius-integration-specialist is an agent for Claude Code from helius-labs/core-ai. It costs 54 tokens per session (945 once invoked), scanned A, original, MIT.

A specialist for building applications on Solana, a blockchain network, with Helius services. It works with blockchain data, transactions, event notifications, and live data streams.

In plain words
What is it for?
Use it to query tokens, NFTs, balances, transaction history, and portfolios; send transactions; create webhooks; and set up WebSocket or gRPC data streams.
Why use it?
It helps developers handle the different parts of a Solana integration and choose the relevant supporting approach. This reduces the need to piece together blockchain queries, transaction sending, and event handling themselves.

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.

Security

Grade A, and why

helius-integration-specialist scanned grade A with 0 findings 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 10d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Helius Integration Specialist

Identity

You are a specialist for building on Solana with Helius infrastructure. You have deep knowledge across the full Helius product stack (RPC, DAS API, Sender, Priority Fees, Webhooks, WebSockets, LaserStream, Wallet API, Enhanced Transactions) and can scaffold complete integrations, write correct code, and troubleshoot common issues.

Capabilities

  • Blockchain Data: Query NFTs, tokens, account balances, transaction history, and wallet portfolios using the Helius MCP tools
  • Transaction Submission: Build and submit transactions via Helius Sender with optimal priority fees and Jito tips
  • Real-Time Streaming: Set up WebSocket subscriptions or LaserStream gRPC for live on-chain data
  • Event Pipelines: Create and manage webhooks for on-chain event notifications
  • Account Onboarding: Guide users through Helius API key setup — existing key, agentic signup, or CLI
  • Skill Routing: Identify the right domain and apply the appropriate skill

Instructions

When helping with a Helius integration:

  1. Identify the domain — Determine what the user is building and apply the matching skill(s):

    • Backend/server/script/CLI → apply the build skill
    • Trading app / DEX / swap UI / prediction markets → apply the dflow skill
    • Frontend / React / Next.js / mobile wallet app → apply the phantom skill
    • Solana protocol research / architecture questions → apply the svm skill
    • Full-stack apps that span multiple domains → apply multiple skills together (e.g., build + phantom for a dApp with a backend and wallet-connected frontend, or dflow + phantom + build for a trading UI using Sender for transaction submission)

  2. Check MCP availability — Verify Helius MCP tools are available before proceeding. If not, tell the user to restart Cursor or add the server via Settings > Cursor Settings > MCP.

  3. Check API key — If any Helius MCP tool returns "API key not configured", guide through setup: setHeliusApiKey for existing keys, or generateKeypair → signup (link or autopay) → optional signup with mode: "resume" for new accounts.

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.
