Overview

Helius MCP is an official MCP server operated by Helius Labs, distributed as the helius-mcp npm package. It exposes tools for Solana wallet balances/holdings, NFT and token asset data, transaction parsing, chain-state queries, and webhook/streaming setup (Enhanced WebSockets, LaserStream gRPC), authenticated with a user-supplied Helius API key. An agent builder plugs this in as the Solana data/RPC layer for wallet, asset, and transaction-history tooling.

Self-reported rows are the project’s own words, dated when we recorded them — not a check. Only reproduced and reviewed rows carry a mark. None of these rows is a safety or quality rating.

Install — reproduced in a container Jul 21, 2026

Runtime: Node.js (npm package, runs via npx)

claude mcp add helius npx helius-mcp@latest
export HELIUS_API_KEY=YOUR_API_KEY
{"mcpServers": {"helius": {"command": "npx", "args": ["helius-mcp@latest"]}}}

You supply: HELIUS_API_KEY (Helius API key; also resolvable from ~/.helius/config.json), HELIUS_NETWORK optional (mainnet-beta default, devnet supported)

Add to CursorAdd to VS Code
claude mcp add satohub-helius-mcp -- npx helius-mcp@latest

A local server: your client runs this command on your machine. Installing runs third-party software under your own credentials. Sato Hub publishes the documented invocation and, where the harness reproduced it, the date it did — neither is a safety review.

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 46 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Every one of them passed, so the rate covers them too.

A gap is a day we have no attributable observation — never a zero. Thirty points is the whole shape the free layer carries; the daily rows behind it stay in the snapshot series.
