Sui MCP Server

|

A Model Context Protocol (MCP) server for Sui blockchain integration, providing seamless Sui Move development, blockchain interaction, and debugging capabilities within Cursor IDE.

Sui MCP Server Features

This project implements an MCP server specifically for Sui blockchain development and data querying, seamlessly integrating Sui's powerful features into MCP-compatible IDEs like Cursor.

Sui Development Environment Management

• Environment Switching: Easily switch between testnet, mainnet, and devnet environments
• Network Status Monitoring: Track network health, version, and TPS
• Network Time: Get blockchain network time for time-dependent operations

Smart Contract Development

• Contract Interface Parser: Parse and display human-readable Move module Interfaces
• Contract Verification: Verify and publish smart contract source code

Blockchain Interaction

• Wallet Management: Create test wallets with pre-funded SUI tokens
• Faucet Integration: Request test tokens for development
• Object Explorer: Retrieve and inspect Sui objects
• Transaction Builder: Build transactions from high-level descriptions
• Token Standards Support: Recognize and parse different token standards

Debugging & Optimization

• Error Decoding: Translate error codes into human-readable explanations with fix suggestions
• Gas Analysis: Analyze transaction gas usage and recommend optimizations

Ecosystem Integration

• Explorer Integration: Generate links to Sui Explorer for transactions, addresses, and objects

Installation

Prerequisites

• Node.js 18+

Setup

1. Clone the repository

git clone https://github.com/your-username/sui-mcp-server.git
cd sui-mcp-server

2. Install dependencies

npm install

3. Configure environment

cp .env.example .env

Edit the .env file according to your needs.

4. Build the server

npm run build

Usage

Starting the server

npm start

Integration with Cursor IDE

Once properly configured, the Sui MCP server will automatically connect with Cursor IDE. To add the MCP server in Cursor:

1. Open Cursor
2. Go to File -> Preferences -> Cursor Settings -> Features -> MCP Server
3. Add a new MCP server pointing to this project's startup script

Example Usage in Cursor

// Get Sui network status
const status = await mcp.callTool("sui_network_status", {
  random_string: "any"
});
console.log(status);

// Create a test wallet
const wallet = await mcp.callTool("sui_create_new_wallet", {
  network: "testnet"
});
console.log(wallet);

// Get contract Interface
const abi = await mcp.callTool("sui_get_contract_interface", {
  packageId: "0x1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef",
  format: "markdown"
});
console.log(abi);
