One way you could test the MCP server is installing LM Studio locally, connecting it to your MCP and now you run everything locally, so as long as your computer is running, the AI can play factorio

I expected this to hapen one day :D Nice initiative!

I'd like to offer some advice regarding the setup. You might have already figured these out in the past few months but if not then here it goes:

For an LLM to succeed playing factorio you'd probably need a different type of harness - coding ...

Interesting. How far Claude went into playing the game and building a factory, in your testing?


Not very far. I've got a couple of blog posts with some random thoughts but in general it's not very good. It burns through tokens so I can't let it just run for days on end. In my experience it will ...

You're building an AI agent to automate playing Factorio, an automation game. Cool! That's the spirit!

I'm not sure where this fits in terms of the Boards here. It's not actually a mod and it's only sort of a tool. I've been working on a Factorio MCP server which lets you wire up Factorio to a language model and let it try and play Factorio. I'll be honest up front and say that I haven't had much ...

“Space Age” downloads include the Base Game as well as the Expansion content. The DLC features SpaceAge/ElevatedRails/Quality can be en/disabled through the in-game Mods menu if you want a classic experience or to load a non-DLC save or join a multiplayer server.

Good Luck!

... would be extremely embarassed because of the jankiness.


Maybe you never working on a home-brew game engine wrote in C++, with a headless server that work using UDP (CITE ME A MODERN GAME OTHER THAN FACTORY THAT USE UDP maybe cs:go 2 ?), with a lua API so powerful you can pretty much do ...

... environment.

I do the same. I love rsync. I've got a copy of my saves local, but I back them up after every safe to another hard rive on my server, and then back that server up every week or so, onto two other sets of hard drives.
Storage space is so cheap that it's almost free. To me, it ...

Factorio multiplayer games are self hosted. If the official public server list provided by wube goes down, multiplayer games will continue working.

are there any plans to disable multiplayer matching servers for older versions? We're running a heavily modded game (~150mods, 500 ingame hours in) which we cannot easily upgrade to the latest version. (or is this version independent anyways?)

The matchmaking API has not changed fundamentally since ...

Hi all,

are there any plans to disable multiplayer matching servers for older versions? We're running a heavily modded game (~150mods, 500 ingame hours in) which we cannot easily upgrade to the latest version. (or is this version independent anyways?)
The main reason to try upgrade would be, if we ...

... make the reseach go faster, but I just couldn't be bothered. :oops:


the REAL correct solution would've been loading up that save on a factorio server, thankfully i have a server of my own that i self host some of my other stuff on, that was what i did when i built my 1.1 megabase and needed to ...

... and "span". The "grid-world" constituting one of the not so many very different structure. That also is the same from what i saw when joining multiplayer server. Not sure what's used otherwise to consider "what players do.

There are also minor reasons, like "faster trains are more dangerous" :lol:

... over time there's less and less of those "solutions" players mention that are totally new to me. It feels like when i join a random multiplayer server, i can identify/recognize "everything" how it works, which was the choice made. Even when seeing a mess of combinator, the question one may ask ...

... to get a user API key - or setting LAN mode. The Client would crash all the time when my packet-injector/capturer would mess with its end, but the Server daemon never crashed from invalid input - just dropped the Client.

I was able to get the server to Reply to a Replay attack - but could not ...

... health, etc.
These will be detected (in multiplayer) by factorios deterministic nature, as several posters above already mentioned. Note that the server is prevented from using resource based cheats as well.
Knowledge based: Anything giving you a knowledge advantage without changing the game state ...

... just spoofing its input timestamp.


I did some more reading (https://factorio.com/blog/post/fff-302) and it's even tighter than you assume. The server acts as an aggregator and relay for client inputs. It waits until every client has submitted its inputs, then forwards the entire input "blob" for ...

... been transmitted from the other clients yet. You could assume the other players will do nothing, but that will almost never be correct on a busy server. Maybe it could fake high latency, and wait until it receives all the other players' actions before sending its own action to them. But then it ...
