Vintage Story server upkeep in four jobs
A Vintage Story server needs steady upkeep: settings change, saves need copies, mods break after game updates and players report errors that only the log explains. Four jobs matter. Each one below names the tools that Cascadia Merge 2.9.26 uses on Windows 10 and 11 and shows what you review before anything changes.
Edit serverconfig.json on a Vintage Story dedicated server
You want a new ServerName and a limit of 10 players on your own dedicated server. Choose the data folder as the working folder of the chat first. The agent uses glob to find serverconfig.json, read_file to show the current values and copy_file to keep a copy of the file before it touches anything. Then edit_file changes the two lines and shows the diff. Stop the server first. You read the diff in Ask first mode, press Accept, and start the server again with your own start script.
Tool trace
glob serverconfig.json → 1 match
read_file serverconfig.json → read
copy_file serverconfig.json → copied
edit_file serverconfig.json → +2 -2Copy the saves before a game update
Your world lives in one .vcdbs file in the Saves folder, so a copy of that folder is your safety net. Stop the server so the save is not in use. The agent uses list_dir to find the Saves folder and copy_file to place the world file in the Backups folder, then Shell runs your own backup script and the card shows its real exit code. Make 1 copy before every game update, mod change and settings change. Test the copy. You restore it once into a spare folder and confirm that it opens, because a copy that was never restored is only a guess.
Tool trace
list_dir Saves/ → found
copy_file Saves/default.vcdbs → copied
Shell backup-saves.cmd → exit 0Look up Vintage Story admin commands in the docs
Before you type a command into the console, you want its exact spelling. The agent uses web_search and http_get to read the official documentation, then write_file saves what you need into a short text file in your working folder. The file holds 5 commands: /op, /role, /whitelist, /announce and /stop. Check each line. You compare it with the documentation page before you use the file, because a model can mistype a command and only entries from the official list belong in it.
Find the mod behind a failed start
After a game update the server stops on start, and mods are the usual cause. The agent uses grep to search the server log for the line where a mod failed to load, and read_file opens that mod's modinfo.json so you see its name and version next to the error. Players also ask which mods to remove when RAM usage grows, and list_dir over the Mods folder gives you the list to decide from. Go slowly. Remove 1 mod at a time. You move the file yourself, or let edit_file prepare a change in Ask first mode, and restart after each step.
How it differs from a typical chat assistant
A chat assistant only suggests. Cascadia Merge 2.9.26 runs the tools itself and shows each real result as a card, so you review facts from your own files instead of guesses.
| Typical chat assistant | Cascadia Merge | |
|---|---|---|
| Reading files | You paste the file text into the chat | Opens the file itself with read_file |
| Changing a setting | Describes the new line in plain text | Shows a diff that you accept or reject |
| Running a script | You run it and report the output back | Runs it with Shell and shows the exit code |
| Searching logs | You copy log lines into the chat | Searches the log with grep and lists matches |
How to get started
- Download the 34 MB setup program from this page and install it on Windows 10 or 11.
- Open Cascadia Merge and connect a cloud model, a local model or the built-in model.
- Choose your server's data folder as the working folder of a new chat.
- Describe one job, such as changing MaxClients, and review the card or the diff that the agent shows.
Who uses it and when
Hosts who run a world for friends use it for routine jobs: changing ServerName or MaxClients, copying the Saves folder before a game update and checking which port players use, which is 42420 by default. Each step is a card. You see the command result or the diff, not a summary.
A beginner who wants to learn how to make mods can ask the agent to explain a modinfo.json line by line. Vintage Story modding starts with JSON asset files for blocks, items and recipes, while code mods are written in C#. Read every answer. Ask first pauses before any change.
Mod authors work there too. The agent edits JSON assets or C# source in the working folder, runs your own build or start command with Shell, and the card shows the real exit code so you know whether the step finished.
Questions about running the server
What is a Vintage Story server?
A Vintage Story server is a separate program that you run on your own PC or on a machine you own or rent, so that players can join your world from the multiplayer menu of the game. You can also move a hosted or single-player world onto it. It runs on its own.
Is cascadiacoders.com the official Cascadia Merge website?
Yes, cascadiacoders.com is the official Cascadia Merge website. The download button gives the original build of the setup program, about 34 MB, and you can compare its SHA-256 checksum with the published manifest before you run it. Check the checksum. Questions go through the Send feedback button inside the app.
What are Vintage Story server commands?
Server commands are text instructions that you type into the server console or into game chat while you hold admin rights. For example, /announce sends a message to everyone and /stop shuts the server down. Use only official commands. Cascadia Merge can look them up in the documentation for you.
Who can use Vintage Story admin commands?
The people who hold admin rights can. The /op command gives a player admin rights, /role assigns a role and /whitelist manages the whitelist. Keep that list short. Protect the world with a password or a whitelist as well, because anyone with admin rights can run these commands on your server.
Can the agent help with Vintage Story modding?
Yes, it can read and edit the files of a mod. Content mods are JSON asset files and code mods are written in C#, and every mod describes itself in a modinfo.json that the agent can open. It can also search the log for a failed mod. You read each diff.
What if I have trouble with my server?
The first step is the server log. The agent runs grep over it for the line where a mod failed to load or a player was disconnected, and shows each match in a card. Read the match. You decide on the fix, and Ask first mode pauses before any change that edits a file.
Are the results of Cascadia Merge always right?
No. The agent shows each result as it is, such as an exit code or a diff, but a model can misread a log or suggest a wrong value. Read every diff, keep a copy of your saves and test each change on the server before your players join the world.
