What is the MCP Monad MCP server?

MCP Monad becomes available to MCP clients through the mcp monad mcp server. This project provides an MCP server for seamless interaction with the Monad testnet. It supports querying blockchain data (balances, transactions, gas prices, blocks) and interacting with the CoinflipGame smart contract for playing a coinflip game. The server integrates with Claude Desktop.

What MCP Monad does

This project provides an MCP server for seamless interaction with the Monad testnet. It supports querying blockchain data (balances, transactions, gas prices, blocks) and interacting with the CoinflipGame smart contract for playing a coinflip game. The server integrates with Claude Desktop, allowing users to execute commands in natural language.

Installing the mcp monad mcp server

The server is distributed via npm as tsc, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.

Configuration

Before the server will start you need to supply one environment variable: PRIVATE_KEY. Keep credentials in your client's env block or a secrets manager rather than committing them.

Requirements

  • Node.js (v16 or newer) - npm or yarn - Claude Desktop (for MCP Client integration) - A Monad testnet wallet with sufficient MON for transactions and gas fees (required for play-coinflip, send-mon, and send-token) - A .env file configured with: PRIVATE_KEY for the Monad testnet wallet Uniswap V2 contract addresses (UNISWAP_ROUTER_ADDRESS, UNISWAP_FACTORY_ADDRESS) and WMON contract

Where it fits

Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. MCP Monad sits in that group. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.

Practical notes

  • This server runs locally, so it operates with whatever access your machine and its credentials already have. Scope that deliberately rather than by default.
  • It will not start until its required credentials are present, so set those before wondering why the tools never appear.
  • Maintained by Semutireng22, written in TypeScript.
  • MCP clients ask for confirmation before each tool call by default. Keep that on while you learn what the mcp monad mcp server actually does with your data.
  • Every entry in this directory is reviewed by hand before it goes live, and details are checked against the project's own documentation.

Frequently asked questions

It connects MCP Monad to MCP-compatible AI assistants such as Claude and Cursor. Instead of copying data back and forth by hand, the assistant works with MCP Monad directly.
