# MCP Adapter

> Create a Model Context Protocol server for the Solana Agent Kit

# 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:

```bash theme={"system"}
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:

```bash theme={"system"}
mkdir solana-agent-mcp
cd solana-agent-mcp
npm init -y
```

Install the required dependencies:

```bash theme={"system"}
npm install solana-agent-kit @solana-agent-kit/adapter-mcp @solana-agent-kit/plugin-token dotenv
```

Create a `.env` file in your project root:

```env theme={"system"}
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:

```javascript theme={"system"}
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:

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

## Claude Desktop Configuration

1. Open the Claude Desktop configuration file:

   **MacOS:**

   ```bash theme={"system"}
   code ~/Library/Application\ Support/Claude/claude_desktop_config.json
   ```

   **Windows:**

   ```bash theme={"system"}
   code $env:AppData\Claude\claude_desktop_config.json
   ```

2. Add your MCP server configuration:

   ```json theme={"system"}
   {
       "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.

3. Restart Claude Desktop after updating the configuration.

## Customizing Available Actions

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

```javascript theme={"system"}
// 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

1. Start your MCP server (if running manually):
   ```bash theme={"system"}
   node index.js
   ```

2. 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.
