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.

Supported Features and How To Use

Feature	Description	Example Command
get-mon-balance	Check the MON balance for a Monad testnet address.	`check MON 0xa2e57a3A7744eA20B5E2848817e9D66C6cb9f765`

Quick Start

Clone the repository

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

Copy .env.example to .env and configure it

cp .env.example .env

Edit .env with your private key

nano .env

Build and run

npm run build
node build/index.js

Prerequisites

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 address (WMON_ADDRESS)

Configuration and Usage

MCP Server Initialization

In the src/index.ts file, 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"
  ]
});

Setting Up the Environment

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

cp .env.example .env

Edit the .env file with a text editor (e.g., nano, vim, or VS Code) to include the following:

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

Replace 0xyourprivatekeyhere with your Monad testnet wallet's private key (64 hexadecimal characters starting with 0x).

Ensure the .env file is secure and not committed to version control. Add it to .gitignore:

echo .env >> .gitignore

Building and Running the Server

Build the project:

npm run build

Run the MCP server:

node build/index.js

Integration with Claude Desktop

Open Claude Desktop.
Go to Settings > Developer.
Edit claude_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-monad on Windows or /home/user/mcp-monad on Linux).

Restart Claude Desktop.
When prompted, allow MCP access for the chat session (Allow for This Chat).

Notes

Ensure the CoinflipGame contract (0x664e248c39cd70Fa333E9b2544beEd6A7a2De09b) has sufficient funds in its pool to cover potential winnings for play-coinflip. You can check this using a Monad testnet block explorer.
For users on different systems, adjust the project path in claude_desktop_config.json accordingly.

Troubleshooting

Server fails to start: Check logs in Claude Desktop (Settings > Developer) or terminal for errors like "File .env does not exist." Ensure .env is in the project root with a valid PRIVATE_KEY.
Insufficient contract funds: Verify the CoinflipGame contract balance using a block explorer. The contract owner can fund it via the fundGamePool function.
Claude commands not working: Ensure claude_desktop_config.json has the correct project path and restart Claude Desktop.
TypeScript errors: Run npx tsc to check for errors. Update dependencies with:

npm install

Use MCP Inspector for debugging:

git clone https://github.com/modelcontextprotocol/inspector
cd inspector
npm install
npm start

This server cannot be installed

security - not tested

license - permissive license

quality - not tested

remote-capable server

The server can be hosted and run remotely because it primarily relies on remote services or has no dependency on the local environment.

Enables interaction with the Monad testnet to check balances, examine transaction details, get gas prices, and retrieve block information.
