MCP Adapter

The @solana-agent-kit/adapter-mcp adapter provides a framework for creating a Model Context Protocol (MCP) server to handle protocol operations on the Solana blockchain using the Solana Agent Kit.

Installation

Install the adapter alongside the core Solana Agent Kit and your desired plugins:

npm install solana-agent-kit @solana-agent-kit/adapter-mcp @solana-agent-kit/plugin-token dotenv

Features

Supports all actions from the Solana Agent Kit
MCP server implementation for standardized interactions with Claude Desktop
Environment-based configuration
Selective action exposure

Prerequisites

Node.js (v16 or higher recommended)
pnpm, yarn, or npm
Solana wallet with private key
Solana RPC URL
Claude Desktop application

Basic Setup

Create a new project for your MCP server:

mkdir solana-agent-mcp
cd solana-agent-mcp
npm init -y

Install the required dependencies:

npm install solana-agent-kit @solana-agent-kit/adapter-mcp @solana-agent-kit/plugin-token dotenv

Create a .env file in your project root:

SOLANA_PRIVATE_KEY=your_private_key_here
RPC_URL=your_solana_rpc_url_here
OPENAI_API_KEY=your_openai_api_key_here

Create an index.js file with the following code:

import { SolanaAgentKit, KeypairWallet } from "solana-agent-kit";
import { startMcpServer } from '@solana-agent-kit/adapter-mcp';
import TokenPlugin from '@solana-agent-kit/plugin-token';
import * as dotenv from "dotenv";

// Load environment variables
dotenv.config();

// Initialize wallet with private key from environment
const wallet = new KeypairWallet(process.env.SOLANA_PRIVATE_KEY);

// Create agent with plugin
const agent = new SolanaAgentKit(
  wallet,
  process.env.RPC_URL,
  {
    OPENAI_API_KEY: process.env.OPENAI_API_KEY,
  }
).use(TokenPlugin);

// Select which actions to expose to the MCP server
const finalActions = {
  BALANCE_ACTION: agent.actions.find((action) => action.name === "BALANCE_ACTION"),
  TOKEN_BALANCE_ACTION: agent.actions.find((action) => action.name === "TOKEN_BALANCE_ACTION"),
  GET_WALLET_ADDRESS_ACTION: agent.actions.find((action) => action.name === "GET_WALLET_ADDRESS_ACTION"),
};

// Start the MCP server
startMcpServer(finalActions, agent, { name: "solana-agent", version: "0.0.1" });

Update your package.json to add the type field:

{
  "name": "solana-agent-mcp",
  "version": "1.0.0",
  "type": "module",
  "main": "index.js",
  "scripts": {
    "start": "node index.js"
  }
}

Claude Desktop Configuration

Open the Claude Desktop configuration file: MacOS:

code ~/Library/Application\ Support/Claude/claude_desktop_config.json

Windows:

code $env:AppData\Claude\claude_desktop_config.json

Add your MCP server configuration:

{
    "mcpServers": {
        "agent-kit": {
            "command": "node",
            "env": {
                "RPC_URL": "your_solana_rpc_url_here",
                "SOLANA_PRIVATE_KEY": "your_private_key_here",
                "OPENAI_API_KEY": "your_openai_api_key_here"
            },
            "args": [
                "/ABSOLUTE/PATH/TO/YOUR/solana-agent-mcp/index.js"
            ]
        }
    }
}

Replace the path with the absolute path to your index.js file.

Restart Claude Desktop after updating the configuration.

Customizing Available Actions

You can customize which actions are available to Claude by modifying the finalActions object:

// Example of adding more actions from different plugins
const finalActions = {
  // Basic wallet actions
  BALANCE_ACTION: agent.actions.find((action) => action.name === "BALANCE_ACTION"),
  GET_WALLET_ADDRESS_ACTION: agent.actions.find((action) => action.name === "GET_WALLET_ADDRESS_ACTION"),
  
  // Token actions
  TOKEN_BALANCE_ACTION: agent.actions.find((action) => action.name === "TOKEN_BALANCE_ACTION"),
  TRANSFER_ACTION: agent.actions.find((action) => action.name === "TRANSFER_ACTION"),
  
  // Trading actions
  TRADE_ACTION: agent.actions.find((action) => action.name === "TRADE_ACTION"),
};

Testing the Integration

Start your MCP server (if running manually):
```
node index.js
```
Open Claude Desktop and ask questions about Solana, like:
- “What’s my SOL balance?”
- “Show me my token balances”
- “What’s my wallet address?”

Claude will use your MCP server to interact with the Solana blockchain and provide responses based on the available actions. For more detailed information, please refer to the full documentation at docs.sendai.fun.

Solana Agent Kit MCP Server

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
curl -fsSL https://raw.githubusercontent.com/sendaifun/solana-mcp/main/scripts/install.sh -o solana-mcp-install.sh

# 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 (Recommended for clients like Cursor/Cline)

# Install globally
npm install -g solana-mcp

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

Option 3: Build from Source

Clone this repository:

git clone https://github.com/sendaifun/solana-mcp
cd solana-mcp

Install dependencies:

pnpm install

Build the project:

pnpm run build

Configuration

Environment Setup

Create a .env file with your credentials:

# Solana Configuration
SOLANA_PRIVATE_KEY=your_private_key_here
RPC_URL=your_solana_rpc_url_here
OPENAI_API_KEY=your_openai_api_key # OPTIONAL

Integration with Claude Desktop

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

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

Add the Configuration Create or edit the configuration file and add the following JSON: If you installed via npm (Option 1):

{
  "mcpServers": {
    "solana-mcp": {
      "command": "npx",
      "args": ["solana-mcp"],
      "env": {
        "RPC_URL": "your_solana_rpc_url_here",
        "SOLANA_PRIVATE_KEY": "your_private_key_here",
        "OPENAI_API_KEY": "your_openai_api_key"  // OPTIONAL
      },
      "disabled": false,
      "autoApprove": []
    }
  }
}

If you built from source (Option 2):

{
  "mcpServers": {
    "solana-mcp": {
      "command": "node",
      "args": ["/path/to/solana-mcp/build/index.js"],
      "env": {
        "RPC_URL": "your_solana_rpc_url_here",
        "SOLANA_PRIVATE_KEY": "your_private_key_here",
        "OPENAI_API_KEY": "your_openai_api_key"  // OPTIONAL
      },
      "disabled": false,
      "autoApprove": []
    }
  }
}

Restart Claude Desktop After making these changes, restart Claude Desktop for the configuration to take effect.

Available Tools

The MCP server provides all the Solana Agent Kit tools like:

GET_ASSET - Retrieve information about a Solana asset/token
DEPLOY_TOKEN - Deploy a new token on Solana
GET_PRICE - Fetch price information for tokens
WALLET_ADDRESS - Get the wallet address
BALANCE - Check wallet balance
TRANSFER - Transfer tokens between wallets
MINT_NFT - Create and mint new NFTs
TRADE - Execute token trades
REQUEST_FUNDS - Request funds (useful for testing/development)
RESOLVE_DOMAIN - Resolve Solana domain names
GET_TPS - Get current transactions per second on Solana

Security Considerations

Keep your private key secure and never share it
Use environment variables for sensitive information
Consider using a dedicated wallet for AI agent operations
Regularly monitor and audit AI agent activities
Test operations on devnet/testnet before mainnet

Troubleshooting

If you encounter issues:

Verify your Solana private key is correct
Check your RPC URL is accessible
Ensure you’re on the intended network (mainnet, testnet, or devnet)
Check Claude Desktop logs for error messages
Verify the build was successful
