What is MCP Blockchain Server?

The MCP Blockchain Server is a secure bridge between AI assistants and blockchain networks. It allows AI to read blockchain data and prepare transactions while keeping your private keys safe in your own wallet.

How does it work?

The system consists of a server that prepares transactions, a web interface for approval, and secure connections to blockchain networks. You always control the final signing step.

When should I use it?

Perfect when you want AI assistance with blockchain transactions but don't want to compromise security. Great for DeFi interactions, NFT management, and other Web3 activities.

Key Features

Blockchain Data Access
Read balances, contract states and other on-chain information through simple API calls
Transaction Preparation
AI assistants can prepare transactions for your review before you sign them
Multi-Chain Support
Works with Ethereum, Polygon and other EVM-compatible blockchains
Security-First Design
Your private keys never leave your wallet - we never have access to your funds
Wallet Integration
Connect with MetaMask and other popular Web3 wallets
Advantages
Complete control over your private keys
AI can assist with complex blockchain operations
Clear transaction review before signing
Supports multiple blockchain networks
Open source and transparent
Limitations
Requires manual approval for each transaction

Need to trust the AI's transaction preparation

Getting Started

Connect Your Wallet
Use the web interface to connect your preferred Web3 wallet (like MetaMask)
Interact with AI
Ask your AI assistant to perform blockchain operations (check balance, prepare transfer, etc.)
Review Transaction
When a transaction is prepared, review all details in the web interface
Sign and Submit
Approve the transaction in your wallet to execute it on the blockchain
