OpenZeppelin Cairo Contracts

OpenZeppelin Cairo Contracts MCP Server

The OpenZeppelin Cairo Contracts MCP server brings OpenZeppelin's proven security and style rules directly into any AI-driven development workflow, allowing developers to seamlessly prompt their preferred AI assistants to generate secure smart contracts. This revolutionary ChatGPT custom connector and Claude custom connector transforms how developers build on Starknet by ensuring every generated contract follows OpenZeppelin's battle-tested standards.

What is the OpenZeppelin Cairo Contracts MCP Server?

The OpenZeppelin Cairo Contracts MCP Server is a Model Context Protocol (MCP) server that allows AI agents to generate smart contracts using OpenZeppelin Contracts libraries. Each request passes through the Contracts MCP, which injects OpenZeppelin's Wizard logic and returns code that's secure, correct, and follows OpenZeppelin standards.

Key Capabilities and Value Proposition

🛡️ Enterprise-Grade Security

Every line of smart contract code generated by the Contracts MCP is validated against the same rule-set that powers OpenZeppelin's Contracts Wizard, with imports, modifiers, naming conventions, and security checks applied automatically.

The remote MCP server provides 8 specialized tools for generating Cairo smart contracts:

1. cairo-erc20 - Fungible tokens following ERC-20 standard
2. cairo-erc721 - Non-fungible tokens (NFTs) per ERC-721
3. cairo-erc1155 - Multi-token standard implementation
4. cairo-account - Custom smart contract accounts with extensible logic
5. cairo-multisig - Multi-signature contracts with quorum requirements
6. cairo-governor - DAO governance contract implementation
7. cairo-vesting - Token vesting schedules with gradual release
8. cairo-custom - Fully customizable smart contracts

Primary Use Cases and Target Audience

👨‍💻 Starknet Developers

Cairo is the native smart contract language for Starknet, a permissionless decentralized Validity-Rollup, with Rust-inspired syntax allowing developers to write Starknet smart contracts in a safe and convenient manner. This OpenZeppelin Cairo Contracts ChatGPT connector is perfect for:
