Solana Agent Kit MCP Server

Check on Phala

A Model Context Protocol (MCP) server that provides onchain tools for Claude AI, allowing it to interact with the Solana blockchain through a standardized interface. This implementation is based on the Solana Agent Kit and enables AI agents to perform blockchain operations seamlessly.

Overview

This MCP server extends Claude's capabilities by providing tools to:

• Interact with Solana blockchain
• Execute transactions
• Query account information
• Manage Solana wallets

The server implements the Model Context Protocol specification to standardize blockchain interactions for AI agents.

Prerequisites

• Node.js (v16 or higher)
• pnpm (recommended), npm, or yarn
• Solana wallet with private key
• Solana RPC URL (mainnet, testnet, or devnet)

Installation

Option 1: Quick Install (Recommended)

# Download the installation script

# Make it executable and run
chmod +x solana-mcp-install.sh && ./solana-mcp-install.sh --backup

This will start an interactive installation process that will guide you through:

• Setting up Node.js if needed
• Configuring your Solana RPC URL and private key
• Setting up the Claude Desktop integration

Option 2: Install from npm ( recommend for clients like Cursor/Cline)

# Install globally
npm install -g solana-mcp

# Or install locally in your project
npm install solana-mcp

Integration with Claude Desktop

To add this MCP server to Claude Desktop, follow these steps:

1. Locate the Claude Desktop Configuration File

   • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
   • Windows: %APPDATA%\Claude\claude_desktop_config.json
   • Linux: ~/.config/Claude/claude_desktop_config.json

2. Add the Configuration Create or edit the configuration file and add the following JSON:
