There seems to be a issue with update v2.4.0, When I try to connect the plugin to Claude it doesn’t connect at all.

I’m facing the same issue, spent hours thinking it was an issue on my end.
Running claude mcp list shows that
robloxstudio: node dist/index.js failed to connect, while Codex (openAI) works perfectly fine.
I’d suggest you both to integrate with the official MCP posted.
There is nothing that separates these two.

i’ve been having this issue too
robloxstudio-mcp v2.5.0 - Screenshot Capture & One-Command Plugin Install
GitHub | NPM | Download Plugin
Screenshot Capture
AI agents can now see your viewport. The new capture_screenshot tool grabs the Studio viewport as a PNG image and returns it directly in the conversation. Your agent can look at what you’ve built, spot visual issues, and suggest changes based on what it actually sees.
The plugin captures the viewport, reads pixel data in tiles to handle any resolution, and the server encodes it as a PNG. Works with any screen size.
One-Command Plugin Install
No more manually downloading and copying the plugin file. After installing the npm package, just run:
npx robloxstudio-mcp-install-plugin
It grabs the latest plugin from GitHub releases and drops it straight into your Roblox Plugins folder. Works on Windows and macOS.
import_scene Improvements
Scene import now accepts both the original tuple format and a cleaner object format for placements. The object format is easier for AI agents to generate correctly:
{"modelKey": "tree", "position": [10, 0, 5], "rotation": [0, 45, 0]}
Schema has also been updated for broader compatibility with OpenAI and other tool-calling models.
Bug Fixes
Fixed screenshot tiling off-by-one that caused unnecessary extra tile reads. Full Enum.Material mapping for scene imports. Hardened bulk object creation and asset insertion error handling. Resolves #69, #54, #53.
Setup
npx robloxstudio-mcp@latest
npx robloxstudio-mcp-install-plugin
Or install the plugin manually from the GitHub release into your Plugins folder. Enable Allow HTTP Requests in Game Settings > Security.
Claude Desktop / Claude Code config:
{
"mcpServers": {
"robloxstudio": {
"command": "npx",
"args": ["-y", "robloxstudio-mcp@latest"]
}
}
}
Plugin shows “Connected” when ready.

Well for me, it’s working now hehe.
Suggestion to change how insert,edit,delete script lines work with not passing the line number but passing the code in that line
or
start numbering each line of code when getscriptsource is used (eg. --[[1]] code in line 1 \n --[[2]] code in line 2)
Had to disable those 3 tools because every ai model keeps hallucinating the line numbers (they probably had to guess how much \n are in there) resulting in duplicate code, syntax errors everywhere, etc.
And maybe add a compile check to check for syntax errors, really will help a lot
local succ,err = pcall(function() loadstring(script) end) if succ then return "Script Successfully Edited" else return "Error Editing Script:"+err) end
after editing a script

Can we use subagents with this, and do they have access to the MCP tools?
Yes and yes for both of your questions.

It seems that my MCP server either fails to connect or tries perpetually, i am using the roblox plugin for reference.
I have both HTTP requests on and the MCP server is recognized by claude.
boshi, can you really change how “edit script lines” works please?
I think its gonna stop making duplicate code and syntax errors, it will be a big change.
The edit tool is from opencode.
