Overview
What is ZAN MCP Server?
ZAN MCP Server is a Model Context Protocol (MCP) server that connects AI assistants to ZAN.top’s blockchain node services. It provides tools for querying and interacting with multiple EVM-compatible chains, enabling AI to read on-chain data, resolve ENS names, and submit transactions.
How to use ZAN MCP Server?
Install and run via npx without a local install: add a configuration entry to your MCP client (Claude Desktop, Cursor, VSCode) with "command": "npx", "args": ["-y", "zan-mcp-server", "--stdio", "--api-key", "<zan_api_key>"]. For write operations (sending transactions, signing), also supply the chain’s private key using --evm-private-key or --solana-private-key.
Key features of ZAN MCP Server

- Estimate gas, create access lists, and prepare transactions
- Sign and send transactions through an AI assistant interface
FAQ from ZAN MCP Server
What chains does ZAN MCP Server support?
It supports Ethereum (Mainnet, Sepolia, Holesky), BSC (Mainnet, testnet), Polygon (Mainnet, Amoy), Optimism (Mainnet, Sepolia), Arbitrum One (Sepolia), and others like Base, zkSync, Tron, Avalanche, Fantom, Taiko, and Mantle.
How do I get an API key to use the server?
An API key is required and must be obtained from ZAN.top. You pass it via the --api-key argument when starting the server.
What transport and authentication does the server use?
The server uses stdio transport. Authentication is handled through the provided ZAN.top API key; write operations additionally require the chain’s private key.
Are there any runtime dependencies?
The server is distributed as an npm package and runs via Node.js. It can be launched with npx without prior installation.
Does the server support write operations like sending transactions?
Yes, but write operations (e.g., evm_send_transaction, evm_sign_message) require the private key of the corresponding chain to be passed as a startup argument (--evm-private-key or --solana-private-key).
