MCP Server built with the Ping Agent Kit

A Model Context Protocol (MCP) server offering onchain tools for AI, enabling seamless interaction with the Solana blockchain via a standardized interface. Built on the Ping Agent Kit, this implementation allows AI agents to execute blockchain operations efficiently.

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: Install from npm ( recommend for clients like Cursor/Cline)

# Install globally
npm install -g ping-mcp

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

Option 2: Build from Source

1. Clone this repository:

git clone https://github.com/PingAIFun/ping-mcp.git
cd ping-mcp

2. Install dependencies:

pnpm install

3. 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:

1. 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

2. 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": ["ping-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/ping-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": []
       }
     }
   }
   

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

Available Tools

The MCP server provides the following Solana blockchain tools:

• 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:

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

Dependencies

Key dependencies include:

• @solana/web3.js
