Solana Agent Kit MCP Server Utility

This utility provides a framework for creating a Model Context Protocol (MCP) server to handle protocol operations on the Solana blockchain using the Solana Agent Kit.

Features

• Supports all actions from the Solana Agent Kit
• MCP server implementation for standardized interactions
• Environment-based configuration

Prerequisites

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

Installation

pnpm install

Configuration

1. Configure the claude_desktop_config.json file by editing the env fields.

SOLANA_PRIVATE_KEY=your_private_key_here
RPC_URL=your_solana_rpc_url_here

2. Change the Claude Desktop MCP server settings:

For MacOS:

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

For Windows:

code $env:AppData\Claude\claude_desktop_config.json

The final configuration should look like the following (replace the path with your absolute project path):

{
    "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" // e.g /Users/username/Projects/solana-agent-kit-mcp-server/index.js
            ]
        }
    }
}

Note: Make sure to restart Claude Desktop after updating the configuration and building the project.

Building the Project

To build the project, run:

pnpm run build

This will compile the TypeScript code and set the appropriate permissions for the executable.

Project Structure

• src/ - Source code directory
• src/index.ts - Main entry point implementing the MCP server

Usage Examples

Starting the MCP Server

To start the MCP server, use the following command:

Installation

First you'll need to create a node project

pnpm init

Then install the solana-agent-kit, desired plugins and the mcp utility

pnpm add solana-agent-kit @aivy-solana-agent-kit/plugin-token @aivy-solana-agent-kit/adapter-mcp dotenv

Usage

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

dotenv.config();

const wallet = new KeypairWallet(process.env.SOLANA_PRIVATE_KEY)

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

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")!,
};

startMcpServer(finalActions, agent, { name: "solana-agent", version: "0.0.1" });

This will start the server once you start up Claude. You can add actions by simply adding them to the finalActions object.
