Hi @green rain. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
Yes, you can connect ChatGPT to a remote MCP server, which could in principle expose tools for Roblox Studio (or any other service). Here's how it works:
How to Connect ChatGPT to a Remote MCP Server
1. Build or Use a Remote MCP Server
You need a remote MCP server that exposes the tools you want (e.g., tools that interact with Roblox Studio). The server must be publicly reachable over the internet and implement the MCP protocol (SSE or Streamable HTTP transport). [Building MCP servers]
2. Connect It in ChatGPT (Developer Mode)
- Eligibility: Available in beta to Pro, Plus, Business, Enterprise, and Education accounts on the web.
- Enable Developer Mode: Go to Settings → Apps → Advanced Settings → Developer Mode.
- Create an App: Click "Create app" in ChatGPT Apps settings, provide your MCP server's endpoint URL, pick an authentication mechanism (OAuth, No Auth, or Mixed), and click Create. [Developer mode guide]
Once created, the app appears as a draft and you can use it in conversations by selecting it from the tools menu.
3. Use It via the API (Responses API)
You can also call your MCP server programmatically:
from openai import OpenAI
client = OpenAI()
resp = client.responses.create(
model="gpt-5.5",
tools=[
{
"type": "mcp",
"server_label": "roblox_studio",
"server_url": "<https://your-roblox-mcp-server.example.com/sse",>
"require_approval": "never",
},
],
input="Your prompt here",
)
print(resp.output_text)
Important caveat: OpenAI does not provide a pre-built MCP server for Roblox Studio. You (or a third party) would need to build and host an MCP server that exposes Roblox Studio functionality as tools. The knowledge sources do not mention any existing Roblox Studio MCP server or official integration.

Let me check the knowledge base for you again. One moment! :books:
Sure! Here's a simpler breakdown:
Connecting ChatGPT to Roblox Studio via MCP — In Plain Terms
What is MCP?
MCP is basically a standard "plug" that lets ChatGPT connect to external tools and services.
Step 1: You need a "bridge" (MCP server)
Someone needs to build a small server that sits between ChatGPT and Roblox Studio, translating ChatGPT's requests into Roblox actions. This doesn't exist out of the box — you or a developer would need to build it.
Step 2: Connect it to ChatGPT
Once that server exists, you connect it in ChatGPT like this:
- Make sure you have a Pro, Plus, Business, Enterprise, or Education ChatGPT account.
- Go to Settings → Apps → Advanced Settings and turn on Developer Mode.
- Click "Create app", paste in your server's web address, and save. [Developer mode guide]
Step 3: Use it in chat
After that, you can pick your app from the tools menu in a ChatGPT conversation and start using it.
The catch: OpenAI doesn't provide a ready-made Roblox Studio MCP server. The knowledge sources don't mention one existing either. So the main hurdle is finding or building that "bridge" server first.

@viscid gull is buisness the highest?
viscid gullBOT
Let me check the knowledge base for you again. One moment! :books:
No, Business is not the highest plan. Based on the knowledge sources, Enterprise/Edu is the top tier, offering the most controls and features — such as advanced RBAC (role-based access control), the ability to grant developer mode to specific members, and more granular app action controls after publishing. [Developer mode overview]
Here's a quick summary of the plan tiers relevant to MCP/apps, from lowest to highest:
- Free / Go – Limited app support, no custom MCP
- Plus – Custom MCP supported
- Pro – Custom MCP + read/fetch in developer mode; full MCP write actions not available
- Business – Full MCP support (including write actions); admins only can manage developer mode
- Enterprise / Edu – Full MCP support + most advanced admin controls (RBAC, per-user developer mode access, action controls after publishing) [Apps capabilities by plan]

@viscid gull i have a plugin on roblox, it hosts the MCP on http://localhost:58741 BUT it uses PowerShell on pc to do it, i didnt get it to work, do you think i can put the url in chatgpt and it will work?
viscid gullBOT
Let me check the knowledge base for you again. One moment! :books:
Unfortunately, no — putting <http://localhost:58741> into ChatGPT will not work.
The reason is clearly stated in the knowledge sources: ChatGPT only supports remote MCP servers, not local ones.
"Can I connect to a local MCP server? Not currently. Only remote servers are supported." [MCP FAQ]
A localhost address only exists on your own PC — ChatGPT's servers on the internet have no way to reach it.
What you'd need to do instead
To make it work, you'd need to expose your local MCP server to the public internet so ChatGPT can reach it. A common way developers do this is with a tunneling tool like ngrok, which creates a public URL that forwards traffic to your local server. The knowledge sources mention this approach:
"If you want to reach the server from the public internet, there are a variety of ways to do that including with ngrok." [Deep Research MCP guide]
So the general idea would be:
- Keep your Roblox plugin running the MCP server locally on port
58741. - Use a tool like ngrok to create a public HTTPS URL pointing to it.
- Paste that public URL into ChatGPT's app settings instead of
localhost.
However, I can only confirm this is the general approach based on the knowledge sources — I can't guarantee your specific Roblox plugin setup will be compatible, as that depends on details outside of what OpenAI's documentation covers.

@viscid gull tell me now, how do i Connect my roblox MCP to my chatgpt
viscid gullBOT
Let me check the knowledge base for you again. One moment! :books:
Based on our conversation so far, here's a clear step-by-step summary of what you need to do:
Step 1: Make Your Local MCP Server Public
Your Roblox plugin runs on <http://localhost:58741,> which ChatGPT cannot reach. You need to expose it to the internet first (e.g., using a tunneling tool like ngrok). This will give you a public HTTPS URL like <https://abc123.ngrok.io> that points to your local server.
⚠️ This step is essential — ChatGPT only supports remote MCP servers, not local ones. [MCP FAQ]
Step 2: Enable Developer Mode in ChatGPT
- Make sure you have a Plus, Pro, Business, Enterprise, or Edu account.
- Go to Settings → Apps → Advanced Settings.
- Toggle on Developer Mode. [Developer mode guide]
Step 3: Add Your MCP Server as an App
- In ChatGPT, go to Settings → Apps.
- Click "Create app".
- Paste your public HTTPS URL (from Step 1) as the server endpoint.
- Choose an authentication method (No Authentication if your server doesn't require it).
- Click Create. [Developer mode guide]
Step 4: Use It in a Chat
- Open a new chat in ChatGPT.
- Click the "+" (tools) button and select your Roblox app.
- Choose Developer Mode from the menu.
- Start prompting — be explicit, e.g. "Use the Roblox app's [tool name] to…"
