​
Quick Start Guide

This guide will help you set up Solana Agent Kit v2 in your application, including installation, initialization, and embedded wallet integration.

​
Core Installation

First, install the core Solana Agent Kit package: 
npm install solana-agent-kit

​
Install Plugins

You can choose to install specific plugins based on your needs or install all available plugins: 
npm install @solana-agent-kit/plugin-token @solana-agent-kit/plugin-nft @solana-agent-kit/plugin-defi @solana-agent-kit/plugin-misc @solana-agent-kit/plugin-blinks

​
Plugin Navigation

Token Plugin

Transfer tokens, check balances, and deploy tokens with the Token Plugin.

NFT Plugin

Create collections, mint NFTs, and manage digital assets with the NFT Plugin.

DeFi Plugin

Swap tokens, provide liquidity, and interact with DeFi protocols using the DeFi Plugin.

Blinks Plugin

Execute fast and atomic transactions with the Blinks Plugin.

​
Basic Initialization

Here’s how to initialize the agent with a keypair wallet: 
import { SolanaAgentKit, createVercelAITools, KeypairWallet } from "solana-agent-kit";
import TokenPlugin from "@solana-agent-kit/plugin-token";
import NFTPlugin from "@solana-agent-kit/plugin-nft";
import DefiPlugin from "@solana-agent-kit/plugin-defi";
import MiscPlugin from "@solana-agent-kit/plugin-misc";
import BlinksPlugin from "@solana-agent-kit/plugin-blinks";
import { Keypair } from "@solana/web3.js";
import bs58 from "bs58";

// Create a keypair from a private key
const keyPair = Keypair.fromSecretKey(bs58.decode("YOUR_SECRET_KEY"));
const wallet = new KeypairWallet(keyPair);

// Initialize with wallet and optional RPC URL
const agent = new SolanaAgentKit(
  wallet,
  "YOUR_RPC_URL",
  {
    OPENAI_API_KEY: "YOUR_OPENAI_API_KEY",
  }
) 
  .use(TokenPlugin)
  .use(NFTPlugin)
  .use(DefiPlugin)
  .use(MiscPlugin)
  .use(BlinksPlugin);

// Create Vercel AI tools (or use createLangchainTools for LangChain)
const tools = createVercelAITools(agent, agent.actions);

​
Embedded Wallet Integration

For a better user experience, you can integrate with embedded wallets like Privy instead of directly handling private keys. Here’s how to use Solana Agent Kit with the Solana wallet adapter: 
import { SolanaAgentKit, createVercelAITools } from "solana-agent-kit";
import TokenPlugin from "@solana-agent-kit/plugin-token";
import DefiPlugin from "@solana-agent-kit/plugin-defi";
import BlinksPlugin from "@solana-agent-kit/plugin-blinks";
import MiscPlugin from "@solana-agent-kit/plugin-misc";
import { Connection, PublicKey } from "@solana/web3.js";

// Assuming you have a wallet from Privy or another wallet adapter
const wallet = wallets[0]; // From useSolanaWallets() or similar

// Create an agent with the wallet adapter
const agent = new SolanaAgentKit(
  {
    publicKey: new PublicKey(wallet.address),
    signTransaction: async (tx) => {
      const signed = await wallet.signTransaction(tx);
      return signed;
    },
    signMessage: async (msg) => {
      const signed = await wallet.signMessage(msg);
      return signed;
    },
    sendTransaction: async (tx) => {
      const connection = new Connection(
        "YOUR_RPC_URL",
        "confirmed"
      );
      return await wallet.sendTransaction(tx, connection);
    },
    signAllTransactions: async (txs) => {
      const signed = await wallet.signAllTransactions(txs);
      return signed;
    },
    signAndSendTransaction: async (tx) => {
      const signed = await wallet.signTransaction(tx);
      const connection = new Connection(
        "YOUR_RPC_URL",
        "confirmed"
      );
      const sig = await wallet.sendTransaction(signed, connection);
      return { signature: sig };
    },
  },
  "YOUR_RPC_URL",
  {}
)
  .use(TokenPlugin)
  .use(DefiPlugin)
  .use(BlinksPlugin)
  .use(MiscPlugin);

// Create tools for your AI model
const tools = createVercelAITools(agent, agent.actions);

​
MCP Adapter Integration

The Model Context Protocol (MCP) adapter allows you to create an MCP server that Claude Desktop can use to interact with the Solana blockchain. This provides a standardized way for Claude to access Solana functionality.

​
Installation

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

​
Basic Setup

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" });

​
Claude Desktop Configuration

Configure Claude Desktop to use your MCP server:
  1. Edit the Claude Desktop configuration file: MacOS: 
    code ~/Library/Application\ Support/Claude/claude_desktop_config.json
    Windows: 
    code $env:AppData\Claude\claude_desktop_config.json
  2. 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"
            },
            "args": [
                "/ABSOLUTE/PATH/TO/YOUR/MCP/PROJECT/FILE"
            ]
        }
    }
}
  3. Restart Claude Desktop after updating the configuration.
This integration allows Claude to interact directly with your Solana agent through the MCP protocol, providing seamless blockchain functionality within conversations.
