base-gasless-deploy-mcp

MCP server for deploying ERC-20 tokens on Base with zero gas using CDP Paymaster. Falls back to normal gas if no paymaster is configured.

Install

npx -y base-gasless-deploy-mcp

Configuration

Add to your MCP client config (e.g. Claude Desktop):

{
  "mcpServers": {
    "base-gasless-deploy": {
      "command": "npx",
      "args": ["-y", "base-gasless-deploy-mcp"],
      "env": {
        "DEPLOYER_PRIVATE_KEY": "0x...",
        "PAYMASTER_URL": "https://api.developer.coinbase.com/rpc/v1/base/..."
      }
    }
  }
}

Environment Variables

Variable	Required	Description
DEPLOYER_PRIVATE_KEY	Yes (write ops)	Private key for deploying/transferring
PAYMASTER_URL	No	CDP Paymaster RPC endpoint for gasless transactions
CDP_PAYMASTER_URL	No	Alias for PAYMASTER_URL
RPC_URL	No	Base RPC (default: https://mainnet.base.org)

Tools

deploy_gasless_token

Deploy an ERC-20 token on Base. Uses paymaster for zero gas when configured.

Params:

• name (string) - Token name
• symbol (string) - Token symbol
• supply (string, default "1000000") - Total supply in human units
• owner_address (string) - Address that receives all tokens

get_token_info

Get info about a deployed token (name, symbol, supply, owner balance).

Params:

• token_address (string) - Token contract address

estimate_gas_savings

Show how much gas was saved by using the paymaster.

Params:

• token_address (string) - Token contract address

list_deployed_tokens

List all tokens deployed by an address in the current session.

Params:

• deployer_address (string) - Deployer wallet address

transfer_tokens

Transfer ERC-20 tokens gaslessly via paymaster.

Params:

• token_address (string) - Token contract address
• to (string) - Recipient address
• amount (string) - Amount in human units

How It Works

1. Pre-compiled ERC-20 bytecode is embedded in the server (no Solidity compiler needed at runtime)
2. When PAYMASTER_URL is set, transactions are routed through the CDP Paymaster for gas sponsorship
3. If the paymaster fails or isn't configured, transactions fall back to normal gas from the deployer wallet
4. All deployments are tracked in-memory for gas savings reporting
