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, allowing users to execute commands in natural language.

git clone https://github.com/Semutireng22/mcp-monad.git cd mcp-monad npm install

- Copy.env.example to.env and configure it

- 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.envfile configured with:PRIVATE_KEYfor the Monad testnet walletUniswap V2contract addresses (UNISWAP_ROUTER_ADDRESS,UNISWAP_FACTORY_ADDRESS) andWMONcontract address(WMON_ADDRESS)

In thesrc/index.tsfile, the server is initialized with the list of supported features:

const server = new McpServer({ name: "monad-testnet", version: "0.0.1", capabilities: [ "get-mon-balance", "get-token-balance", "get-transaction-details", "get-gas-price", "get-latest-block", "get-multiple-balances", "send-mon", "send-token", "play-coinflip", "get-coinflip-history", "stake-aprmon", "unstake-aprmon", "claim-aprmon", "get-aprmon-balance", "get-aprmon-rate", "get-aprmon-requests", "swap" ] });

To configure the server, copy the example environment file and edit it:

Edit the.envfile with a text editor (e.g.,nano,vim, orVS Code) to include the following:

PRIVATE_KEY=0xyourprivatekeyhere UNISWAP_ROUTER_ADDRESS=0xfb8e1c3b833f9e67a71c859a132cf783b645e436 UNISWAP_FACTORY_ADDRESS=0x733e88f248b742db6c14c0b1713af5ad7fdd59d0 WMON_ADDRESS=0x760AfE86e5de5fa0Ee542fc7B7B713e1c5425701

Replace0xyourprivatekeyherewith your Monad testnet wallet's private key (64 hexadecimal characters starting with0x).

Ensure the.envfile is secure and not committed to version control. Add it to.gitignore:
- Open Claude Desktop.
- Go toSettings > Developer.
- Editclaude_desktop_config.json(typically located in~/.config/Claude/or%APPDATA%\Claude\) and add the following configuration:

{ "mcpServers": { "monad-mcp": { "command": "node", "args": [ "/path/to/mcp-monad/build/index.js" ], "env": { "NODE_ENV": "production" } } } }

Replace/path/to/mcp-monad/with the actual path to your project directory (e.g.,E:\proyek\mcp-monadon Windows or/home/user/mcp-monadon Linux).
- Restart Claude Desktop.
- When prompted, allow MCP access for the chat session (Allow for This Chat).
- Fork the Project
- Create your Feature Branch (git checkout -b feature/AmazingFeature)
- Commit your Changes (git commit -m 'Add some AmazingFeature')
- Push to the Branch (git push origin feature/AmazingFeature)
- Open a Pull Request
