From the repository

Once configured, restart Claude Desktop. Claude will now have access to the Solana blockchain tools. You can ask Claude to:

1. Check a wallet balance:

   What's the balance of the Solana wallet address 5YNmS1R9nNSCDzb5a7mMJ1dwK9uHeAAF4CmPEwKgVWr8?

2. Get the current block height:

   What's the current block height on Solana?

3. Get information about NFTs:

   What NFTs does the wallet address 5YNmS1R9nNSCDzb5a7mMJ1dwK9uHeAAF4CmPEwKgVWr8 own?

Claude will use the MCP server to fetch this information directly from the Solana blockchain via Helius.

Prerequisites

- Node.js (v16 or higher)
- A Helius API key (get one at https://dev.helius.xyz/)
- Claude Desktop application

Installation

1. Clone this repository:

   git clone https://github.com/dcSpark/mcp-server-helius.git

   cd mcp-server-helius

2. Install dependencies:

   npm ci

3. Build the project:

   npm run build

Configuration

Configure Claude Desktop

To configure Claude Desktop to use this MCP server:

3. Add the MCP server configuration:

{
  "mcpServers": {
    "mcp-server-helius": {
      "command": "npx",
      "args": [
        "-y",
        "@mcp-dockmaster/mcp-server-helius"
      ],
      "env": {
        "HELIUS_API_KEY": "your-helius-api-key"
      }
    }
  }
}

Running Locally

HELIUS_API_KEY=your-helius-api-key node build/index.js

You can also run directly using npx:

HELIUS_API_KEY=your-helius-api-key npx @dcspark/mcp-server-helius

Usage

Once configured, restart Claude Desktop. Claude will now have access to the Solana blockchain tools. You can ask Claude to:

1. Check a wallet balance:

   What's the balance of the Solana wallet address 5YNmS1R9nNSCDzb5a7mMJ1dwK9uHeAAF4CmPEwKgVWr8?

2. Get the current block height:

   What's the current block height on Solana?

3. Get information about NFTs:

   What NFTs does the wallet address 5YNmS1R9nNSCDzb5a7mMJ1dwK9uHeAAF4CmPEwKgVWr8 own?

Claude will use the MCP server to fetch this information directly from the Solana blockchain via Helius.

Development

Adding New Tools

To add new tools to the MCP server:

1. Define the tool in src/tools.ts
2. Create a handler function in the appropriate handler file
3. Add the handler to the handlers object in src/tools.ts
