helius

helius is an MCP server for Claude Code, Codex, Cursor, Gemini CLI, OpenCode from helius-labs/core-ai. Its token cost is not measured, scanned A, original, MIT.

A local MCP server that gives AI assistants access to data from Solana, a blockchain network. It is provided through the Helius package.

In plain words
What is it for?
Use it when an AI assistant needs access to Solana blockchain information through the Helius MCP server.
Why use it?
It provides a defined connection for retrieving Solana blockchain data instead of requiring the assistant to work without that data source.

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 yesterday.

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.
