Summary
Wraps Coinbase's CDP Paymaster to let AI agents deploy ERC-20 tokens on Base without paying gas fees. Exposes five tools: deploy_gasless_token for minting new tokens, get_token_info for querying deployed contracts, estimate_gas_savings to track paymaster benefits, list_deployed_tokens for session history, and transfer_tokens for gasless sends. Uses pre-compiled bytecode so you don't need a Solidity compiler at runtime. Falls back to normal gas transactions if the paymaster isn't configured. Requires a deployer private key for write operations and optionally a CDP Paymaster RPC endpoint. Tracks all deployments in memory for reporting. Reach for this when you want Claude to spin up test tokens or handle token operations on Base without burning ETH on transaction fees.

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 namesymbol(string) - Token symbolsupply(string, default "1000000") - Total supply in human unitsowner_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 addressto(string) - Recipient addressamount(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_URLis 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
