OpenZeppelin Stylus Contracts MCP Server

The OpenZeppelin Stylus Contracts MCP Server is a server-based engine that brings OpenZeppelin's Contracts proven security and style rules directly into any AI-driven development workflow. Whether you're writing code in Cursor, Claude, Gemini, Windsurf, or VS Code, Contracts MCP provides AI with the tools it needs to generate safe, correct, and production-ready contracts.

This specialized Model Context Protocol (MCP) server focuses specifically on Stylus-based smart contracts implementing ERC20, ERC721, and ERC1155 token standards for the Arbitrum ecosystem. Thanks to a WebAssembly VM, you can deploy Rust smart contracts with seamless interoperability with the EVM.

Key Capabilities & Value Proposition

🚀 AI-Powered Smart Contract Generation

Each request passes through the Contracts MCP, which injects OpenZeppelin's Wizard logic and returns code that's secure, correct, and follows OpenZeppelin standards
Automated Enforcement of OpenZeppelin Standards Every line of smart contract code generated by the Contracts MCP is validated against the same rule-set that powers our Contracts Wizard. Imports, modifiers, naming conventions, security checks—Contracts MCP applies them all automatically

⚡ Arbitrum Stylus Optimization

Stylus programs are not only orders of magnitude cheaper and faster but also enable what was thought to be previously impossible for WebAssembly: EVM-interoperability
Stylus contracts are significantly faster and have lower gas fees due to the superior efficiency of WASM programs. Stylus makes it viable to consume RAM on the blockchain because it can greatly optimize memory use, enabling new use cases

🔧 Three Specialized Tools

stylus-erc20: Generate fungible token contracts per the ERC-20 standard
stylus-erc721: Create non-fungible token contracts per the ERC-721 standard
stylus-erc1155: Build multi-token contracts per the ERC-1155 standard

🛡️ Enterprise-Grade Security

A secure, modular smart contract library for Arbitrum Stylus, written in Rust and inspired by OpenZeppelin Contracts. Stylus enables high-performance smart contracts in Rust, compiled to WebAssembly (Wasm), for deployment on Arbitrum chains.

Primary Use Cases & Target Audience

🎯 Target Developers:

Rust Developers: Leverage existing Rust expertise for blockchain development
DeFi Builders: Create high-performance token contracts with lower gas costs
Web3 Startups: Rapid prototyping of secure smart contracts using AI
Enterprise Teams: Generate production-ready contracts with automated security compliance

💼 Key Use Cases:

Token Launch Projects: Generate ERC-20 tokens for new cryptocurrencies or utility tokens
NFT Collections: Create ERC-721 contracts for digital art, gaming assets, or collectibles
Multi-Token Platforms: Build ERC-1155 contracts for gaming, metaverse, or hybrid token ecosystems
DeFi Protocols: Develop gas-optimized token contracts for DEXs, lending platforms, and yield farms

🌟 Why Choose This MCP Server:

With the new OpenZeppelin Contracts MCP developers can seamlessly prompt their preferred AI assistants to generate secure smart contracts that enforce OpenZeppelin standards and best practices at every prompt
As a result, regardless of the platform (Cursor, Claude, Gemini, and others), any AI prompt returns predictable, verified, production-ready code
By integrating with Arbitrum's EVM through a WASM virtual machine, Stylus ensures seamless interoperability between Solidity and Stylus-written contracts, significantly boosting performance while reducing gas costs
