Solana RugCheck & Transaction Helper MCP server

The Model Context Protocol (MCP) server enables seamless communication between GOAT and Claude for Desktop, allowing the AI to interact with blockchain functionalities on EVM (Base Sepolia) or Solana chains. This integration lets Claude perform blockchain operations through natural language requests.

Installation

Prerequisites

• Claude for Desktop (download from claude.ai/download)

Setting Up the MCP Server

First, clone the repository and build the required packages:

git clone https://github.com/goat-sdk/goat.git && cd goat
cd typescript
pnpm install
pnpm build

Navigate to the MCP example directory:

cd examples/by-framework/model-context-protocol

Configuring for Claude

1. Create a configuration file based on your preferred blockchain:

# For EVM
cp mcp-evm.example.json mcp-evm.json 

# For Solana
cp mcp-solana.example.json mcp-solana.json

2. Edit the configuration file with your specific values:

   • Absolute path to the parent folder of the model-context-protocol directory
   • Your WALLET_PRIVATE_KEY
   • Your RPC_PROVIDER_URL

3. Copy the configuration to Claude's settings directory:

# For EVM
cp mcp-evm.json ~/Library/Application\ Support/Claude/claude_desktop_config.json

# For Solana
cp mcp-solana.json ~/Library/Application\ Support/Claude/claude_desktop_config.json

4. Restart Claude for Desktop to apply the changes.

Using the MCP Server

After setup, Claude can perform blockchain operations through natural conversation:

Example Commands

You can ask Claude to:

• Check your balance for ERC-20 tokens
• Send ERC-20 tokens to another address
• Verify transactions by checking your balance again

Simply run Claude for Desktop and start chatting with these requests.

Updating the Configuration

If you make changes to the code or configuration:

1. Rebuild the code when necessary:

pnpm build

2. If you modify the configuration file, you must:
   • Copy it again to Claude's settings directory
   • Or manually update the claude_desktop_config.json file
   • Restart Claude for Desktop

This integration allows Claude to understand and execute blockchain operations through natural language conversation, making blockchain interactions more accessible.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "goat-solana" '{"command":"node","args":["solana.js"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "goat-solana": {
            "command": "node",
            "args": [
                "solana.js"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your 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 this to your configuration file:

{
    "mcpServers": {
        "goat-solana": {
            "command": "node",
            "args": [
                "solana.js"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
