Requirements

A Base mainnet wallet private key with USDC
$1 USDC ≈ 10 base images, 6 clean, 5 HD, or 3 pro
No other API keys needed

Get USDC on Base: Coinbase → Bridge to Base, or buy directly on Base.

Example usage

generate_image(prompt="a red panda in a spacesuit", aspect="1:1")
→ { image_url: "https://...", prompt: "...", aspect: "1:1", tier: "image" }

generate_clean(prompt="a product photo of a ceramic mug")
→ { image_url: "https://...", tier: "clean" }   // transparent PNG

generate_hd(prompt="a futuristic city at night, cyberpunk style")
→ { image_url: "https://...", tier: "hd" }       // 4096x4096

generate_pro(prompt="a logo mark, geometric eagle")
→ { image_url: "https://...", tier: "pro" }      // transparent + HD

How it works

Each tool call makes an HTTP request to the ForgeMesh imagegen service gated by the x402 protocol. If payment is required, the MCP automatically signs and broadcasts a USDC transfer from your wallet on Base mainnet — then retries the request. You see the result, your wallet is charged, no manual steps.
