OpenZeppelin Solidity Contracts

OpenZeppelin Solidity Contracts MCP Server

The OpenZeppelin Solidity 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 remote MCP server transforms how developers create smart contracts by providing secure, correct code that follows OpenZeppelin standards through standardized AI integrations. Unlike generic AI code generation, the MCP does not generate templates on top of the AI – it replaces the AI output altogether, fully redefining it via OpenZeppelin's approved schemes. As a result, regardless of the platform (Cursor, Claude, Gemini, and others), any AI prompt returns predictable, verified, production-ready code.

Key Capabilities and Value Proposition

8 Powerful Smart Contract Generation Tools

The OpenZeppelin Solidity Contracts MCP server provides 8 specialized tools for generating battle-tested smart contracts:

1. solidity-erc20 - ERC-20 fungible token implementations using the most used ERC standards
2. solidity-erc721 - Non-fungible token (NFT) contracts per ERC-721 standard
3. solidity-erc1155 - Multi-token standard for both fungible and non-fungible tokens
4. solidity-stablecoin - Experimental stablecoin implementations with ERC-20 compliance
5. solidity-rwa - Real-world asset tokenization contracts
6. solidity-account - ERC-4337 account abstraction contracts
7. solidity-governor - DAO governance contract implementation
8. solidity-custom - Custom smart contract generation with OpenZeppelin patterns

Automated Security Enforcement

Every line of smart contract code generated by the Contracts MCP is validated against the same rule-set that powers the Contracts Wizard. Imports, modifiers, naming conventions, security checks—Contracts MCP applies them all automatically, so you never miss a best practice or introduce a common vulnerability.
