OpenZeppelin Contracts Wizard MCP Server

A Model Context Protocol (MCP) server that allows AI agents to generate smart contracts using the OpenZeppelin Contracts Wizard.

[!WARNING] AI agents determine when and how to use the MCP server and therefore may produce inaccurate results. You should always review any information produced by the AI agent to ensure that any results are accurate and suit your purposes.

Features

Provides tools to generate smart contract source code for the following languages and contract kinds. Resulting contracts use OpenZeppelin Contracts libraries for each language. Tools are named in the format <language>-<contract>.

Language	Contracts
solidity	erc20, erc721, erc1155, stablecoin, rwa, account, governor, custom
cairo	erc20, erc721, erc1155, account, multisig, governor, vesting, custom
stellar	fungible, non-fungible
stylus	erc20, erc721, erc1155
