base-gasless-deploy-mcp

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

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