Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account mrfentmen for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

A local MCP server that connects an assistant to the Helius Solana API for balances, transactions, NFTs and token metadata.

What you can do: Look up Solana account balances through the Helius API. Retrieve transaction details. Inspect NFTs and token metadata. The manifest lists no individual tools, so the exact operations are not documented here.
When to use it: Useful when an assistant needs to answer questions about Solana wallets, transactions, NFTs or tokens and you want that data pulled through Helius rather than manual lookups.
Requirements: Runs as a local process installed from the npm package @mrfentmen/helius-mcp over stdio, so Node.js and npm are needed. The manifest declares no authentication, environment variables or headers, but the Helius API normally requires an API key; how it is supplied is not documented here. Network access to Helius is required.

Before you install

The server talks to a third-party API, so the addresses, transactions and tokens you query are sent to Helius. No credentials are declared in the manifest, yet a Helius API key is likely needed and may be stored in local configuration. Treat any key as a secret and check the package source before installing.

Installation

In SourceWeft
