cook4fun-mcp

An MCP server that lets any MCP-compatible agent launch and trade coins on cook4.fun, a Uniswap-V3-native launchpad on the Robinhood chain (chainId 4663).

It runs locally on your own machine (stdio transport), signs with your own wallet, and talks straight to the chain. There is no hosted service and nothing to pay for: your client (Claude Desktop, Cursor, Cline, Windsurf, and other MCP clients) starts it on demand.

Tools

Tool	What it does	Wallet needed
cook4fun_list_coins	List the newest coins with market caps	no
cook4fun_wallet	Show the trading wallet address and ETH balance	yes
cook4fun_launch	Launch a new coin (deploys token + opens its V3 pool, optional first buy)	yes
cook4fun_buy	Buy a coin with ETH (slippage-protected)	yes
cook4fun_sell	Sell a coin back to ETH by amount, percentage, or all (auto-approves)	yes
cook4fun_claim	Claim reward-sharing fees	yes

Coins are referenced by contract address (0x…) or $TICKER.

Setup

Add the server to your MCP client's config. No install step is required: npx fetches and builds it on first run.

Claude Desktop (claude_desktop_config.json), Cursor, Cline, Windsurf, and most clients use the same shape:

{
  "mcpServers": {
    "cook4fun": {
      "command": "npx",
      "args": ["-y", "github:htunaa/cook4fun-mcp"],
      "env": {
        "COOK4FUN_PRIVATE_KEY": "0xYOUR_WALLET_PRIVATE_KEY"
      }
    }
  }
}

Restart the client and the cook4fun_* tools appear.

Configuration

Env var	Required	Default	Notes
COOK4FUN_PRIVATE_KEY	for trading	none	Wallet private key (0x…, 32 bytes). Needs ETH on chain 4663 for launch fee, gas, and buys. Read-only tools work without it.
COOK4FUN_RPC_URL	no	https://rpc.mainnet.chain.robinhood.com	Custom RPC endpoint.
COOK4FUN_LAUNCHPAD_ADDRESS	no	0xc12F…A352 (live V2)	Override the launchpad contract.
COOK4FUN_SLIPPAGE_BPS	no	1000 (10%)	Default slippage tolerance for buys/sells, in basis points.

⚠️ Security: the server can spend everything in this wallet. Fund it with only what you want the agent to trade, and treat the key like any other secret. The key stays on your machine; it is never sent anywhere except to sign transactions locally.

Example prompts
