Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

mcp.json · Universal config
{
  "mcpServers": {
    "asset-gen": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-asset-gen"
      ],
      "env": {
        "API_KEY": "<API_KEY>"
      }
    }
  }
}

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

Details

From the project README

mcp-asset-gen

npm version

This tool allows Claude to speak to OpenAI, and use gpt-image-1 to generate image assets. This can be pretty useful for game or web development, when you need to print individual assets.

Requirements

  • Node
  • An OpenAI API Key
    • Note that this requires an organization, with ID verification at the moment.

Installation

  1. Get an API KEY from the OpenAI website.

  2. Export it in your shell as API_KEY.

export API_KEY=sk-proj-....
  1. Then, paste this into that same shell:
jq --arg apiKey "$API_KEY" \
'.mcpServers = (.mcpServers // {}) | 
 .mcpServers["mcp-asset-gen"] = {
   type: "stdio",
   command: "npx",
   args: ["mcp-asset-gen"],
   env: { API_KEY: $apiKey }
 }' ~/.claude.json > ~/.claude.tmp && mv ~/.claude.tmp ~/.claude.json
  1. You're done! Ask Claude to generate you an image for something, and you'll see
> generate a small logo image that i could use for my arcade game

 I'll generate a logo for your arcade game. Please provide a more specific description of what you'd like to see in the logo (colors, style,
  game theme, etc.) for better results.

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
