An MCP server that connects an AI assistant to Helius, a service providing data from the Solana blockchain. It can provide blockchain balances, transactions, assets, and Jupiter swap data.

Use it to inspect Solana wallets and activity, look up assets and transactions, and work with Jupiter swap information.

It removes the need to build a separate connection for retrieving this Solana data. It requires a Helius API key.

Security

Grade A, and why

helius 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 2d 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.

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.
