In plain words

Why use it?
It provides a configured connection to Solana data without requiring the assistant integration to implement that connection itself.

Written for no agent in particular: it speaks MCP, so any client can run it. Also seen: listed in a Claude config.

One of 6 entries in .mcp.json upstream. Installing this one merges just its entry into your config; the other 5 are separate, each on its own page.

Good fit Use it when an assistant needs to query or work with Solana blockchain data through the Helius service; 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 9d 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.

Origin

This is a copy

100% identical to helius — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Changes

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.
