Factorio Copilot! — AI Agent for Blueprint Generation

[Arefsa78]

Hi all,

I've been thinking about how modern LLMs could assist with generating Factorio blueprints — especially in JSON format — and wanted to share a simple idea that could evolve into something pretty useful.

Idea Overview

A core AI agent, powered by an LLM, with the ability to:

• Search the factorio.school blueprint database by keyword
• Query the Factorio wiki for game mechanics, numerical values, and block properties

The goal would be to generate valid blueprint JSONs based on a natural language prompt like:

“Build a green science pack factory with a throughput of 60/m, using belts and inserters.”

Minimum Requirements

• Access to the factorio.school database for blueprint search and comparison
• Full read access to the Factorio wiki to retrieve necessary stats and ratios
• Internalized or parsed knowledge of the Factorio blueprint JSON format (including entity positions, tiles, and settings)

That's the core concept — lightweight but with a lot of potential!

Suggestions?

Would love to hear what others think — particularly:

• Is there an existing tool or plugin that already does part of this?
• What would be the best way to represent the “blueprint generation chain” (e.g., planner → LLM → validator → visualizer)?
• Any interest in collaborating on a prototype or plugin?

Let me know what you think!

---

Would you like me to submit this version or help you break it into issues/tasks for better collaboration?

PS: I used llms to make a better propusal. I have a lower confidence as this text shows, and I am trying to get better in English. ƪ(˘⌣˘)ʃ

I connected the agent to the databases using MCP. But it needs more tools for better answers.

Here is the first results:

User:

Build a Logistic science pack factory with a throughput of 60/m

Agent:

I found a blueprint for a Logistic Science Pack factory designed to produce 100 logistic science packs per minute. The factory inputs are 10 iron plates per second and 3 copper plates per second to achieve this output.

Since you want a throughput of 60/min (which is 60 Science Packs per minute), this blueprint can be scaled down or used partially to meet your requirement, as it already exceeds the throughput you want.

Here is the blueprint data in JSON format for the Logistic Science Pack factory that produces 100 per minute. You can import and build this factory in your game and adjust as needed:

{
  "blueprint": {
    "description": "This blueprint produces 100 logistic science pack per minute (100 green SPM)\n Input: \n- 10 iron plates per sec \n- 3 copper plates per sec  ",
    "entities": [
      {
        "entity_number": 1,
        "name": "assembling-machine-1",
        "position": { "x": -1.5, "y": 167.5 },
        "recipe": "logistic-science-pack",
        "recipe_quality": "normal"
      },
      {
        "entity_number": 2,
        "name": "transport-belt",
        "position": { "x": 1.5, "y": 166.5 },
        "direction": 8
      },
      // ... (rest of the entities as in the blueprint, truncated for brevity)
    ],
    "label": "Green Science 100 SPM. Logistic science pack[item=logistic-science-pack]",
    "version": 562949954404356
  }
}

If you want, I can provide the complete blueprint JSON or create a version configured exactly for 60/min throughput. Would you prefer that?
