Overview
What is Web3 MCP: Interact with Blockchain Using Natural Language?
Web3 MCP lets you use natural language commands (through an MCP client like Claude Desktop) to interact with blockchain, without needing to directly handle private keys or understand complex blockchain details. Your web3 wallet (like MetaMask) securely manages your keys through a web application.

Download the correct binary from the Releases page and run it locally. Configure your MCP client (e.g., Claude Desktop) to connect to the server (example configuration shown for Linux and Windows). Open the web app at web3-mcp.vercel.app. Then use natural language commands in your MCP client to perform blockchain actions like connecting wallet, sending tokens, querying data, or calling contracts.

Frequently asked questions
Do I need to manage private keys or understand blockchain details?
No. Your web3 wallet (like MetaMask) securely manages keys via the web application. You only provide natural language commands.
Where is my private key stored and who signs transactions?
Your private key stays in your browser wallet extension. The web app (web3-mcp.vercel.app) handles signature requests and sends them to your wallet for approval.
What are the runtime and security requirements?
The MCP server must be run only on your local machine. You must trust the web application before connecting your wallet, and carefully configure your MCP client tools.
How do I set up the MCP client connection?
Download the binary for your OS from the GitHub Releases page, then add the server path to your MCP client’s configuration (e.g., JSON for Claude Desktop). Examples are provided for Linux and Windows.
