What is the MCP Server?
The MCP server is an AI service provided by OpenZeppelin that allows developers to generate smart contract code that meets their requirements through API calls. It is based on the core functionality of Contracts Wizard and supports multiple blockchain languages such as Solidity, Cairo, etc.How to use the MCP Server?
You can use it in two ways: 1) Directly access the MCP service hosted by OpenZeppelin. 2) Run your own MCP server instance locally. Both ways provide REST API interfaces for program calls.Use Cases
Suitable for developers who need to generate smart contracts in batches, platforms that build smart contract development tools, and projects that want to integrate contract generation functionality into their own applications.Main Features
Multi-chain Support
Supports multiple blockchain smart contract languages such as Solidity (EVM chains), Cairo (Starknet), Stellar, and Stylus.
API-driven
Provides standardized REST API interfaces for easy integration into various development tools and workflows.
Highly Customizable
Supports configuring various attributes and functions of the contract through parameters, such as token name, total supply, permission settings, etc.
Advantages
No need to manually write basic contract code, improving development efficiency.
The generated code has been audited by OpenZeppelin, ensuring security.
Supports multiple mainstream blockchain platforms.
Can be deployed locally to protect code privacy.
Limitations
Currently mainly supports standard contract templates, and complex business logic still needs to be developed manually.
Local deployment requires certain server resources.
The code generated by AI still needs manual review and testing.
How to Use
Choose the Usage Method
Decide whether to use the service hosted by OpenZeppelin or deploy your own local MCP server.
Configure Parameters
Prepare the parameters required for API calls, including contract type, attributes, and function options.
Call the API
Send an HTTP request to the MCP server to obtain the generated contract code.
Usage Examples
Generate an ERC20 Token Contract
Create a token contract named 'GameCoin' with a total supply of 1 million and the ability to mint new tokens.
Generate a Pausable ERC721 NFT Contract
Create an art NFT contract that supports administrators to pause all transfer operations.
