MCP Wallet

A comprehensive Web3 wallet SDK based on the MCP (Model-Context-Protocol) for interacting with Monad and other EVM-compatible blockchains. This library provides a secure, feature-rich wallet implementation that can be integrated into any JavaScript/TypeScript application or used directly with AI assistants that support MCP.

🤖 MCP Integration - Core Features

MCP Wallet is primarily designed to work with MCP-enabled AI assistants. The Model Context Protocol (MCP) is an open standard that enables secure, two-way connections between AI models and external tools like this wallet.

What is MCP?

MCP (Model-Context-Protocol) is a protocol that allows AI models to interact with external tools and services. In the context of this wallet:

• It enables AI assistants to help users manage their crypto assets securely
• It provides standardized ways for LLMs to access wallet functionality
• It maintains security boundaries to protect private keys and sensitive operations
