Model Context Protocol Server for ZAN.top node services.

Introduction

ZAN MCP Server is a server implementation based on the Model Context Protocol specification, specifically designed for ZAN.top blockchain node services. It provides various tools and interfaces for blockchain interaction, enabling AI assistants to seamlessly access and process blockchain data through the MCP protocol.

Features

- Multi-chain Support: Supports multiple EVM-compatible chains including Ethereum, Polygon, BSC, Arbitrum, and Optimism
- Convenient Blockchain Queries: Provides blockchain information, address resolution, and other features
- High-reliability Node Service: Based on ZAN.top's high-performance node service
- Standard MCP Protocol: Fully compliant with Model Context Protocol specification
- Extensible Architecture: Supports easy addition of new blockchain tools and services

Supported Blockchains

- Ethereum: Mainnet, Sepolia, Holesky test networks
- BSC: Mainnet, testnet
- Polygon: Mainnet, Amoy testnet
- Optimism: Mainnet, Sepolia testnet
- Arbitrum: One (Mainnet), Sepolia testnet
- Others: Base, zkSync, Tron, Avalanche, Fantom, Taiko, Mantle

Add this to your claude_desktop_config.json:

{
  "mcpServers": {
    "zan": {
      "command": "npx",
      "args": [
        "-y",
        "zan-mcp-server",
        "--stdio",
        "--api-key",
        "<zan_api_key>"
      ]
    }
  }
}

  "inputs": [
    {
      "type": "promptString",
      "id": "zan_api_key",
      "description": "ZAN Node Service API Key",

> Note: For write operations (e.g., sending transactions, signing messages), you need to provide the corresponding chain's private key:
> - For EVM chains: --evm-private-key <private-key>
> - For Solana: --solana-private-key <private-key-base58>

Project Integration

import { createStdioServer } from 'zan-mcp-server';
// Create and start server

const server = createStdioServer({

  // Configuration options

});
// Handle server lifecycle
