Web3 Assistant MCP is an MCP server that provides multi-chain capabilities for interacting with blockchain networks and smart contracts directly from AI agents. It connects compatible Model Context Protocol clients, such as Claude Desktop or Cursor, to decentralized ecosystems across Ethereum and compatible EVM chains. Web3 developers, blockchain researchers, and DeFi analysts use this server to inspect contract code, run read operations, and interact with on-chain protocols without switching between disparate browser extensions or web interfaces. By wrapping Web3 interactions in standard MCP tool interfaces, the server enables conversational assistants to retrieve blockchain data, analyze smart contract structures, and prepare transactions for verification. This simplifies cross-chain workflows and accelerates testing, auditing, and operational monitoring on decentralized networks.
Visit the project repository at https://github.com/LaplaceMan/web3-assistant-mcp to review the prerequisite requirements and setup details. 2. Clone the repository locally or install the package following the instructions in the project README. 3. Open your MCP client configuration file (for example, claude_desktop_config.json for Claude Desktop). 4. Add Web3 Assistant MCP to your mcpServers configuration object, specifying the executable command and any required environment variables or RPC URLs mentioned in the repository documentation. 5. Save the configuration file and restart your MCP client to enable the server tools.
