Catapulta MCP

Enable AI models to easily connect to Web3 and deploy smart contracts in +20 EVM networks without cryptocurrencies using the Catapulta MCP (Model Context Protocol).

Features

• Deployment Command Generation: AI-powered generation of deployment commands with support for multiple networks
• Safe Command Execution: Controlled execution of CLI commands with built-in safety checks
• Wallet Management: Generate, manage wallets and get gas funding through simple commands
• Network Support: Extensive network support including:
  • Ethereum networks (mainnet, testnets)
  • Layer 2 solutions (Arbitrum, Optimism, Base)
  • Alternative chains (BSC, Gnosis, Scroll)
• Advanced Deployment Options:
  • Gas optimization with gas-hawk mode

Installation

# Clone the repository
git clone https://github.com/catapulta-sh/catapulta-mcp.git
cd catapulta-mcp

# Install dependencies
npm install

Usage

Basic Usage

import { McpServer } from '@modelcontextprotocol/sdk/server/mcp.js';
import { StdioServerTransport } from '@modelcontextprotocol/sdk/server/stdio.js';

// Create an MCP server
const server = new McpServer({
    name: 'catapulta-cli-server',
    version: '0.1.0',
});

// Start the server with StdIO transport
const transport = new StdioServerTransport();
server.connect(transport).catch((error) => {
    console.error('[MCP Error]', error);
    process.exit(1);
});

Deployment Command Generation

// Example of generating a deployment command
const command = await server.tool('generate_deploy_command', {
    script_path: 'path/to/script',
    network: 'matic',
    sponsor: true,
    gas_hawk: true
});

Supported Networks

The following networks are supported for deployments:

• Ethereum: main, goerli, sepolia
• Layer 2:
  • Arbitrum: arbitrum, arbitrumGoerli, arbitrumSepolia
  • Optimism: optimism, optimismGoerli, optimismSepolia
  • Base: base, baseTestnet, baseSepolia
• Alternative Chains:
  • BSC: bsc, bscTestnet
  • Gnosis: gnosis, gnosisTestnet
  • Scroll: scroll, scrollSepolia
  • And many more...

Security

The implementation includes several security measures:

• Whitelist of allowed commands
• Input validation for all parameters
• Controlled execution environment
• Error handling and logging

Development

Prerequisites
