Token Minter MCP

An MCP server providing tools for AI agents to mint ERC-20 tokens, supporting 21 blockchains.

Features

• Deploy new ERC-20 tokens with customizable parameters.
• Query token metadata (name, symbol, decimals, total supply).
• Initiate token transfers (returns transaction hash without confirmation).
• Retrieve transaction details by hash.
• Check native token balance of the current account.
• Access token metadata via URI.
• Interactive prompt for deployment guidance.

Tools

• deployToken: Deploys a new ERC-20 token (name, symbol, initialSupply, decimals, chainId).
• transferToken: Transfers ERC-20 tokens (tokenAddress, toAddress, amount, chainId).
• getTransactionInfo: Retrieves transaction details (txHash, chainId).
• getTokenBalance: Queries the balance of a specific ERC-20 token for the current account.
• getTokenInfo: Queries ERC-20 token metadata (tokenAddress, chainId).
• getBalance: Checks native token balance (chainId).

Resources

• tokenMetadata: Exposes token metadata via token://{chainId}/{address}.

Prompts

• deployTokenGuide: Guides token deployment with required parameters (chainId).

Prerequisites

• Node.js v18.x or higher
• npm (typically bundled with Node.js)
• A valid Infura API key for EVM network access
• An Ethereum private key for signing transactions

Installation

1. Clone the Repository: bash git clone https://github.com/kukapay/token-minter-mcp.git cd token-minter-mcp/server

2. Install Dependencies: bash npm install

Configuration

{
  "mcpServers": {
    "Token-Minter-MCP": {
      "command": "node",
      "args": ["path/to/token-minter-mcp/server/index.js"],
      "env": {
        "INFURA_KEY": "your infura key",
        "PRIVATE_KEY": "your private key"
      }
    }
  }
}

Usage

1. Examples:

   I want to create a new token called 'RewardToken' with the symbol 'RWD' on Arbitrum. It should have 5 million tokens in initial supply and use 6 decimal places.

   Token deployment initiated on Arbitrum (chainId: 42161)! Name: RewardToken Symbol: RWD Decimals: 6 Initial Supply: 5000000 tokens Transaction Hash: 0xabc123... Note: Use 'getTransactionInfo' to check deployment status.

   Can you tell me how much POL I have in my wallet on the Polygon network?

   Account Balance on Polygon (chainId: 137): Address: 0xYourAddressHere Balance: 25.3478 POL

   What’s the balance of my newly created token on Polygon?

   Token Balance on Polygon (chainId: 137): Address: 0xYourAddressHere Token: 0xYourTokenAddressHere Symbol: ABCD Balance: 10000000.00 ABCD

   Please transfer 150.75 USDC from my account to 0xRecipientAddressHere on Polygon."

   Transfer initiated on Polygon (chainId: 137)! Token: 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174 To: 0xRecipientAddressHere Amount: 150.75 (150.75 tokens) Transaction Hash: 0xdef456... Note: Use 'getTransactionInfo' to check transfer status.

   What’s the status of my token deployment transaction with hash 0xabc123... on Arbitrum?

   Transaction Info on Arbitrum (chainId: 42161): Hash: 0xabc123... From: 0xYourAddressHere To: Contract Creation Value: 0 ETH Status: Success Deployed Contract Address: 0xNewTokenAddressHere

   Give me the details of the token at address 0xNewTokenAddressHere on Arbitrum.

   Token Info on Arbitrum (chainId: 42161): Address: 0xNewTokenAddressHere Name: RewardToken Symbol: RWD Decimals: 6 Total Supply: 5000000

   How do I deploy a token on Polygon? What details do I need to provide?

   To deploy a token on Polygon (chainId: 137), use the "deployToken" tool with these parameters: - name: The token's full name (e.g., "MyToken") - symbol: The token's ticker (e.g., "MTK") - initialSupply: Amount in token units (e.g., 1000000 for 1M tokens, default 1,000,000) - decimals: Optional number of decimals (default is 18) - chainId: Optional chain ID (default is 1 for Ethereum)

2. Local Testing:

   Intall dependencies:

   bash cd token-minter-mcp npm install

   Start a local Hardhat node:

   npx hardhat node

   Use chainId: 1337 in your prompts to test locally.
