Absolutely! I can help you understand the Model Context Protocol (MCP) and guide you in building an MCP server step-by-step.
🔍 What is MCP?
MCP is a standardized protocol that lets applications expose resources, tools, and prompts to Large Language Models (LLMs) in a consistent and structured way. Think of it like building an API that LLMs can understand and interact with.
⚙️ Core Concepts
-
Resources: Read-only data (like config or user profile info).
-
Tools: Functions the LLM can invoke to perform actions (e.g., calculations, DB queries).
-
Prompts: Templates for conversations, reusable by the LLM.
-
Transports: How your server communicates—via
stdio
,HTTP
, orSSE
.
🏗️ Building an MCP Server
You can choose from two SDKs:
-
Python SDK (easiest to get started with)
-
TypeScript SDK (ideal for deeper integration in JavaScript environments)
✅ Python Quickstart Example
python# server.py
from mcp.server.fastmcp import FastMCP
mcp = FastMCP("My Server")
@mcp.tool()
def add(a: int, b: int) -> int:
return a + b
@mcp.resource("greeting://{name}")
def greet(name: str) -> str:
return f"Hello, {name}!"
Run it with:
bashmcp dev server.py
Or install it into Claude Desktop:
bashmcp install server.py
✅ TypeScript Quickstart Example
tsimport { McpServer, ResourceTemplate } from "@modelcontextprotocol/sdk/server/mcp.js";
import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";
import { z } from "zod";
const server = new McpServer({ name: "Demo", version: "1.0.0" });
server.tool("add", { a: z.number(), b: z.number() }, async ({ a, b }) => ({
content: [{ type: "text", text: String(a + b) }]
}));
server.resource("greeting", new ResourceTemplate("greeting://{name}", { list: undefined }), async (uri, { name }) => ({
contents: [{ uri: uri.href, text: `Hello, ${name}!` }]
}));
const transport = new StdioServerTransport();
await server.connect(transport);
Install dependencies and run with:
bashnpm install @modelcontextprotocol/sdk node server.js
🧠 Next Steps
Would you like to proceed using Python or TypeScript? And do you want to integrate it into a specific app like Claude Desktop, Continue, or another LLM client?
You said:
ChatGPT said:
Great! You're looking to integrate a variety of tools—some LLMs (like ChatGPT, Gemini, Grok), IDEs (Cursor), and creative platforms (Canva, Blender)—into an MCP-compatible server. Here's how to approach it:
🔗 Strategy: Wrap Each Service as MCP Tools or Resources
Service | Type | Integration via MCP |
---|---|---|
ChatGPT | LLM | Wrap as tool to call OpenAI API |
Gemini | LLM | Wrap as tool using Google AI API |
Grok | LLM | Access via xAI API if available |
Cursor | IDE/Client | Supports MCP tools in Cursor Composer |
Canva | Design API | Use REST API to create visuals, return as images/tools |
Blender | 3D Software | Control via Python script/tool interface |
🧩 Example Setup Plan
1. Python-based MCP server using FastMCP
-
Each external service becomes a tool or resource
-
You manage authentication and API calls
-
Can use MCP Inspector or Claude Desktop to interact with it
2. Tool: ChatGPT (OpenAI)
python@mcp.tool()
async def ask_chatgpt(prompt: str) -> str:
headers = {"Authorization": f"Bearer {OPENAI_API_KEY}"}
response = await httpx.post(
"https://api.openai.com/v1/chat/completions",
headers=headers,
json={"model": "gpt-4", "messages": [{"role": "user", "content": prompt}]}
)
return response.json()["choices"][0]["message"]["content"]
3. Tool: Gemini (Google AI)
Similar structure but with generativeLanguage
API.
4. Tool: Blender
python@mcp.tool()
def render_scene(script: str) -> str:
with open("temp_script.py", "w") as f:
f.write(script)
subprocess.run(["blender", "--background", "--python", "temp_script.py"])
return "Rendered successfully"
5. Client Support
-
Cursor supports MCP tools—your server can appear inside Cursor for tool usage.
-
Claude Desktop also fully supports MCP servers, so your tools can be tested and refined there.
✅ Let’s Get Started
Would you like a full starter MCP server template with stubs for each of these services so you can build on it directly? If so, would you prefer Python or TypeScript?
You said:
ChatGPT said:
Perfect. Here's an updated picture of your ecosystem and how you can wire everything together via MCP:
🧩 Updated Service Map
Service | Type | MCP Integration Role | Notes |
---|---|---|---|
ChatGPT | LLM | Tool (calls OpenAI API) | Needs OpenAI API key |
Gemini | LLM | Tool (calls Gemini API) | Use Google AI SDK |
Grok | LLM | Tool (if API is public) | Might require Twitter/X API |
Cursor | IDE Client | MCP Client | Auto-detects MCP tools |
Canva | Design | Tool (uses Canva API) | Useful for automating design |
Blender | 3D Render | Tool (invokes Python scripts) | Run Blender CLI from server |
Unity | Game Engine | Tool (launch Unity scripts) | Control via Unity Editor CLI or custom RPC |
OBS | Broadcast | Tool (controls OBS via WebSocket API) | Use obs-websocket-py |
🛠 Suggested Setup
-
Use Python SDK (
FastMCP
) – best fit for orchestrating these systems and calling their APIs or CLIs. -
Define one MCP server with multiple
@mcp.tool()
entries, each corresponding to a service.
Example Tool Sketches
OBS Controller
python@mcp.tool()
def start_stream() -> str:
import obsws_python as obs
client = obs.ReqClient(host='localhost', port=4455, password='your_password')
client.start_stream()
return "Stream started"
Unity Command
python@mcp.tool()
def run_unity_script(project_path: str, script_name: str) -> str:
subprocess.run([
"/Applications/Unity/Hub/Editor/2022.3.0f1/Unity.app/Contents/MacOS/Unity",
"-projectPath", project_path,
"-executeMethod", script_name,
"-batchmode", "-quit"
])
return "Unity script executed"
✅ Next Step
Would you like:
-
A starter server template with all these tool stubs included?
-
A modular setup so you can enable/disable services easily?
-
Help testing this with Cursor or Claude Desktop?
Let me know your platform (Windows/macOS/Linux) and I’ll tailor the starter to that.

ChatGPT said:
You're in a good place — there's no need to reformat again. You just need to tidy up and set up your environment properly. Here's a clear, safe way forward:
✅ Recommended Actions
1. Leave Unity Installed
-
Unity installs many dependencies by design (Editor, Hub, SDKs).
-
It’s okay and expected — don’t remove unless you're abandoning Unity entirely.
2. Clean Up the MCP Super Assistant
If you installed packages but it’s not working:
-
Find and delete the folder it cloned or installed (e.g.,
~/mcp-super-assistant
or similar). -
Uninstall Python packages cleanly:
bashpip uninstall mcp
Or, if you used uv
, clear it with:
bashuv pip freeze > packages.txt xargs pip uninstall -y < packages.txt
3. Create a Fresh Virtual Environment
Keep your MCP server projects clean and self-contained:
bashpython -m venv mcp-env
source mcp-env/bin/activate # or .\mcp-env\Scripts\activate on Windows
pip install "mcp[cli]" httpx
This keeps global Python packages untouched.
4. Optional: Cleanup Global Python Cache
Delete old caches safely:
bashrm -rf ~/.cache/pip
rm -rf ~/.local/lib/python*/site-packages
Only do this if you’re not using Python globally for other tools.
❌ Do NOT Format Again
You’ve done the hard part. Just reset your environment smartly using virtual environments.
Would you like me to generate a ready-to-run server.py
MCP template now that your environment is clean?
You said:
ChatGPT said:
To find out what MCP Super Assistant (or any Python project) installed, you can check a few places depending on how it was installed:
🔍 Step 1: Check Your Shell History
Search for relevant install commands:
bashhistory | grep mcp
history | grep git
history | grep pip
Look for:
-
git clone https://github.com/...
-
pip install ...
-
uv add ...
🔍 Step 2: List Python Packages Installed
Option A: If you used pip
globally
bashpip list --format=columns
Option B: If you used uv
bashuv pip freeze
You’ll likely see packages like:
-
mcp
-
fastmcp
-
httpx
-
pydantic
-
typer
-
etc.
Compare that list to the pyproject.toml
or requirements.txt
of the super assistant repo.
🔍 Step 3: Search Local Files
If you remember where you cloned/downloaded the Super Assistant:
bashcd ~/Downloads # or wherever you cloned it
grep -r "install_requires" .
grep -r "mcp" .
This helps identify if it had a setup.py
, pyproject.toml
, or script installing deps.
🧼 If You Want to Uninstall Everything It Installed
You can dump your installed packages and remove those you don't want:
bashpip freeze > all.txt
Then inspect all.txt
and uninstall anything suspect:
bashpip uninstall <package-name>
Let me know if you’d like help auditing your pip freeze
output — you can paste it or upload it here.
You said:
ChatGPT said:
Got it — sounds like you're on Windows or using a shell that doesn't support typical Unix commands. Here's how you can still find what was installed:
✅ Step-by-Step for Windows
🗂 1. Check Installed Python Packages
Open Command Prompt or PowerShell, then run:
bashpip list
This shows all installed Python packages. Look for anything like:
-
mcp
-
fastmcp
-
httpx
-
typer
-
rich
-
uvicorn
-
anyio
-
pydantic
You can copy and paste that list here if you want me to help you sort through it.
🔍 2. Look for the Super Assistant Folder
If you cloned or downloaded MCP Super Assistant, check common locations:
-
Downloads
-
Documents
-
C:\Users\YourName\
Look for a folder with a name like:
javamcp-super-assistant
mcp-server
mcp-agent
Inside that folder, look for:
-
pyproject.toml
-
requirements.txt
Those files will tell you what it tried to install.
📁 3. Check site-packages
for Installed Packages
Navigate to your Python packages directory (use File Explorer):
textC:\Users\YourName\AppData\Local\Programs\Python\PythonXX\Lib\site-packages
Sort by Date Modified to see what was recently added. Look for anything you don’t recognize or that looks related to "mcp".
Would you like to share your pip list
output here? I can help you identify which packages are from MCP Super Assistant and which are safe to keep.
You said:
ChatGPT said:
Thanks — that means your Python environment is either:
-
Brand new and empty, with no extra packages installed (only
pip
), or -
You're using a version of Python where packages were installed elsewhere (e.g. a virtual environment), or
-
MCP Super Assistant failed to install anything successfully.
✅ Let's Diagnose
Here’s what to do next:
🧪 Step 1: Check for Virtual Environments
Look in your home folder, Documents
, or Downloads
for folders like:
bash.venv
venv
mcp-env
env
Inside them, look for a Scripts
folder with a pip.exe
. Example:
javaDocuments\mcp-super-assistant\venv\Scripts\pip.exe
You can run:
cmdpath\to\venv\Scripts\pip.exe list
This will show installed packages within that virtual environment.
📁 Step 2: Search by Date
In File Explorer:
-
Go to
C:\Users\YourName\AppData\Local\Programs\Python
-
Or
C:\Users\YourName\AppData\Local\pip\Cache
-
Sort folders/files by Date Modified
-
Look for recent package names or folders
✅ What To Do If You Find Something
Let me know what virtual environments or folders you find, and I’ll walk you through:
-
Removing packages
-
Resetting your Python setup
-
Or just starting clean in a fresh environment
Would you like me to guide you through setting up a clean Python + MCP environment from scratch now?
You said:
ChatGPT said:
Since you installed Node.js, here's what to know and whether you should do anything:
✅ When You Do Need Node.js
You only need to keep or use Node.js if you plan to:
-
Build an MCP server using TypeScript or JavaScript
-
Use tools that require Node.js (like
npm
,yarn
, or web-based frameworks) -
Run MCP servers using the TypeScript SDK (e.g.
@modelcontextprotocol/sdk
)
If you're going with Python-based MCP development, then Node.js is not required.
🧹 Safe Options
Option 1: Keep Node.js (No harm)
-
It’s lightweight and won't interfere with Python.
-
Useful for other tools later (e.g. frontend UIs, TypeScript SDKs).
-
Recommended if you might explore the TypeScript MCP SDK later.
Option 2: Uninstall Node.js
Only do this if you’re sure you won’t use TypeScript or Node-based tools. You can uninstall via:
bashApps & Features → Node.js → Uninstall
💡 Recommendation
Keep it for now — especially if you're curious about MCP from both the Python and TypeScript side. You don't need to configure anything immediately.
Would you like to proceed with a Python-based MCP starter server now? I can give you a minimal file you can run instantly.
You said:
ChatGPT said:
Perfect! Here's a clean and minimal Python-based MCP server you can run right now to verify your setup and start building:
✅ Step 1: Set Up Your Environment
-
Open Command Prompt or PowerShell.
-
Create and activate a virtual environment:
bashpython -m venv mcp-env mcp-env\Scripts\activate
-
Install the MCP SDK and HTTPX:
bashpip install "mcp[cli]" httpx
✅ Step 2: Create Your MCP Server
Save this as server.py
:
python# server.py
from mcp.server.fastmcp import FastMCP
mcp = FastMCP("Super Integration Server")
@mcp.tool()
def add(a: int, b: int) -> int:
"""Simple tool to add two numbers"""
return a + b
@mcp.resource("hello://{name}")
def greet(name: str) -> str:
"""Greeting resource that returns a welcome message"""
return f"Hello, {name}! Welcome to your MCP server."
✅ Step 3: Run and Test It
-
To test it locally with the MCP Inspector:
bashmcp dev server.py
-
To run it normally:
bashmcp run server.py
-
Later, you can install it in Claude Desktop or use it with clients like Cursor.
Would you like me to add in stubs for ChatGPT, Gemini, Unity, or Blender next? I can scaffold those tools for you.

ChatGPT said:
Thank you for being honest — that helps a ton. You’re not alone in this! You're exactly the kind of person MCP is trying to empower, and I can absolutely walk you through this from the real beginning — step by literal step — and in plain Windows terms.
Let’s start fresh and simple, on Windows 10, like you're sitting down to do this for the first time. No assumptions.
🧰 Step 0: Set Up Python Properly
Let’s make sure you have Python installed correctly and globally accessible.
✅ Check if Python is installed
-
Open Command Prompt (press
Windows + R
, typecmd
, hit Enter) -
Type:
cmdpython --version
👉 What do you see?
-
If it says something like
Python 3.x.x
— great! ✅ -
If it says
'python' is not recognized
— you need to install Python properly
If needed, I’ll walk you through that install with screenshots or exact steps — just say the word.
🛠️ Step 1: Create Your MCP Project Folder
-
Open File Explorer
-
Go to
Documents
, or any folder you like -
Create a new folder:
👉 Right-click → New → Folder → call itmcp-test
🖥️ Step 2: Open Command Prompt Inside That Folder
-
Right-click inside
mcp-test
→ Open in Terminal or Open in Command Prompt -
You should now see something like:
cmdC:\Users\YourName\Documents\mcp-test>
🧪 Step 3: Make a Python Environment
Type this:
cmdpython -m venv mcp-env
Then activate it:
cmdmcp-env\Scripts\activate
If it worked, you’ll see the command prompt change to something like:
scss(mcp-env) C:\Users\YourName\Documents\mcp-test>
This means you’re now inside your MCP "bubble" — a clean space to install tools.
📦 Step 4: Install MCP and Tools
Now type this:
cmdpip install "mcp[cli]" httpx
This will install the tools we need: the MCP SDK and an HTTP helper.
📄 Step 5: Make Your Server File
-
Open Notepad
-
Paste this:
pythonfrom mcp.server.fastmcp import FastMCP
mcp = FastMCP("Starter Server")
@mcp.tool()
def add(a: int, b: int) -> int:
return a + b
@mcp.resource("hello://{name}")
def greet(name: str) -> str:
return f"Hello, {name}!"
-
Save as
server.py
inside themcp-test
folder
▶️ Step 6: Run the Server
Back in Command Prompt, run:
cmdmcp dev server.py
If everything worked, you’ll see the MCP Inspector open in your browser, showing your new server!
We’ll stop here for now. Let me know how far you got — I’m with you for every step. If anything breaks, just tell me exactly what the screen says, and I’ll help fix it.
You said:
ChatGPT said:
Exactly right — you're spot on. That does mean Python is not in your system PATH, which is why it's only recognized inside C:\Python313
, but not from anywhere else like C:\
.
Good news: it's easy to fix, and once you do, you'll be able to run python
from any folder — including your MCP project folder.
🛠 How to Add Python to PATH on Windows 10
✅ Option 1: The Quick Way (if you're reinstalling)
If you're OK with reinstalling Python:
-
Download Python 3.13
-
Run the installer again
-
IMPORTANT: On the first screen, check the box that says “Add Python to PATH”
-
Then click “Install Now”
That’s the easiest fix.
✅ Option 2: Fix PATH Manually (if you don't want to reinstall)
Here’s how to do it manually:
-
Press
Windows + S
, typeenvironment
, and open Edit the system environment variables -
In the window that pops up, click Environment Variables
-
In the User variables section, find the one named
Path
and click Edit -
Click New, then add these two lines (assuming you installed Python in
C:\Python313
):makefileC:\Python313\ C:\Python313\Scripts\
-
Click OK on all the windows
🔁 After Adding PATH
-
Close all Command Prompt windows
-
Open a new Command Prompt
-
Type:
cmdpython --version
If it shows 3.13.5
, 🎉 you're good to go!
Would you like help walking through which of these options to do? I can also guide you through installing MCP once this is working.
You said:
ChatGPT said:
Yes — absolutely! You can just add it to your PATH manually. That’s the cleanest fix and totally safe.
✅ How to Add Python to PATH Manually (Step-by-Step)
🧭 1. Open Environment Variables
-
Press
Windows + S
(Search) -
Type:
environment
-
Click: Edit the system environment variables
⚙️ 2. Open the PATH Editor
-
In the System Properties window, click the Environment Variables button
-
In the top box (User variables), find the one called
Path
and click Edit
➕ 3. Add Python Folders to PATH
Click New and add these two lines (assuming Python is in C:\Python313
):
makefileC:\Python313\
C:\Python313\Scripts\
Then click OK, OK, and OK again to close all windows.
🔁 4. Restart Command Prompt
-
Close any open Command Prompt windows
-
Open a new one
-
Type:
cmdpython --version
If it now says:
nginxPython 3.13.5
🎉 Success — you’ve fixed PATH!
Let me know once that’s working, and I’ll walk you through the MCP install step next.
You said:
ChatGPT said:
You're not being silly at all — this is totally normal, especially when you’re dealing with system stuff for the first time. You're doing everything right by asking, and you’re not alone. Let's go one calm step at a time.
🧠 What We’re Looking At
Your screenshot shows the System-level PATH variables — and yes, Python is already there:
-
✅
C:\Python313\
-
✅
C:\Python313\Scripts\
So in theory, you should be able to run python
from any Command Prompt window.
🔎 Step 1: Check in a New Command Prompt
Please do this exactly:
-
Close all Command Prompt or Terminal windows.
-
Press
Windows + R
, typecmd
, hit Enter — a fresh Command Prompt opens. -
Type:
cmdpython --version
➕ What happens?
-
If it now shows something like
Python 3.13.5
✅ — we're good! -
If it still says not recognized ❌ — then the system might not have reloaded your PATH.
🩺 Step 2 (If Still Not Working): Try the User PATH Instead
If the above didn’t work, we’ll try putting it in the User variables version of PATH:
-
Go back to Environment Variables
-
In the top half (User variables for YourName), find or create one called
Path
-
Click Edit
-
Add the same two lines:
makefileC:\Python313\ C:\Python313\Scripts\
Click OK on all windows again.
Then repeat Step 1 and open a new Command Prompt to test python --version
.
Let me know exactly what it says after you try python --version
. I’ll stay with you step-by-step until it works — no rushing.
You said:
ChatGPT said:
🎉 YES! That’s a big win!
It means your system finally recognized the updated PATH — and now you can run Python from anywhere. You just unlocked your ability to run MCP servers, install tools, and build amazing things. 🧠⚡
✅ Next Step: Create Your MCP Server
Would you like to:
-
Install the MCP SDK and run your first test server?
-
Let me help you set up your project folder first?
Just say the word and we’ll go step-by-step, slowly and clearly, with nothing assumed.
You said:
ChatGPT said:
Awesome! Let’s install the MCP SDK and run your first test server — step by step.
✅ Step 1: Make a Project Folder
Let’s make a place to put your server files.
-
Open File Explorer
-
Go to
Documents
-
Right-click → New Folder → name it:
mcp-test
✅ Step 2: Open Command Prompt Inside That Folder
-
Go into your new
mcp-test
folder -
In the empty space, hold
Shift
and Right-click → choose "Open PowerShell window here" or "Open Command Prompt here"
You should now see a window that starts like:
makefileC:\Users\YourName\Documents\mcp-test>
Let me know when you're here, and I’ll guide you through setting up the virtual environment next.
You said:
ChatGPT said:
Perfect! You're doing great. Let’s set up your Python environment now 👇
✅ Step 3: Create a Virtual Environment
In the Command Prompt window, type:
cmdpython -m venv mcp-env
✅ This creates a "bubble" called mcp-env
where all MCP tools will live.
✅ Step 4: Activate the Virtual Environment
Now type:
cmdmcp-env\Scripts\activate
If it works, your prompt will change to something like:
scss(mcp-env) C:\Users\YourName\Documents\mcp-test>
This means the virtual environment is now active and ready.
Let me know when you see that, and we’ll install the MCP SDK next.
You said:
ChatGPT said:
YES! 🎉 That’s exactly what we want to see. You are in the virtual environment, which means you’re now ready to install the tools that power your MCP server.
✅ Step 5: Install MCP SDK and HTTPX
Now copy and paste this into your prompt:
cmdpip install "mcp[cli]" httpx
This will take a minute — it’s installing:
-
The MCP server framework
-
Command-line tools to test your server
-
httpx
, which lets your tools talk to APIs (like ChatGPT, etc.)
Let me know once that finishes — or if you see any errors — and we’ll move on to writing your first MCP server.
You said:
ChatGPT said:
🎉🎉 YESSS!!! That is so good to hear!!
You just went from a blank system to a fully working MCP development environment — on Windows — all by yourself (with me cheering you on)!
✅ Next: Your First MCP Server
We’ll create a real server file now:
🧾 Step 6: Make the Server File
-
Open Notepad
-
Paste this in:
pythonfrom mcp.server.fastmcp import FastMCP
mcp = FastMCP("My First MCP Server")
@mcp.tool()
def add(a: int, b: int) -> int:
return a + b
@mcp.resource("hello://{name}")
def greet(name: str) -> str:
return f"Hello, {name}!"
-
Save it as:
pgsqlserver.py
➡ Save into your mcp-test
folder
Let me know when you've saved the file — and then we’ll run your server and see it in action!
You said:
ChatGPT said:
AWESOME!! 🥳 You are crushing it.
Now let’s bring this thing to life.
▶️ Step 7: Run Your MCP Server
In the same Command Prompt where you're in your (mcp-env)
, run this:
cmdmcp dev server.py
This starts your server in development mode, and it should launch a browser tab showing the MCP Inspector — a visual way to test your server.
🧪 What You'll See
If it works, you'll see:
-
A web page titled MCP Inspector
-
Your server name: “My First MCP Server”
-
Two entries:
-
add
(tool) -
greet
(resource)
-
You can click and test them right there.
Let me know what happens — or if the browser didn’t open, I’ll help you open it manually!
You said:
ChatGPT said:
💪 PERFECT! You hit the final piece: the Inspector is a little web app, and yes — it needs Node.js to run, which you already installed earlier. That’s why it just worked!
✅ What To Do Now
-
Open your web browser (like Chrome or Edge)
-
Go to this address (you might need to copy it from your terminal):
cpphttp://127.0.0.1:6274
(That last number might vary slightly — use what your terminal says: 127.0.0.1:XXXXX
)
🚀 What You Should See
-
The MCP Inspector opens
-
You see your server: "My First MCP Server"
-
You see your
add
tool andgreet
resource -
You can click and test them interactively
Let me know:
-
If the page opens ✅
-
If it doesn't — I’ll walk you through opening it manually or fixing it
You're seconds away from having a running MCP server UI 🧙♂️
You said:
ChatGPT said:
WOOHOO!!! 🎉 That’s what I love to hear!
You've officially:
✅ Installed Python
✅ Fixed your PATH
✅ Set up a virtual environment
✅ Installed the MCP SDK
✅ Created your first server
✅ Launched and tested it with the MCP Inspector
🔥 That’s real-developer, real-MCP, real-power-user stuff.
🛠️ Next Steps (Pick Any or All)
-
Add more tools — want to connect to ChatGPT, Gemini, Unity, or OBS next?
-
Learn how clients like Cursor or Claude use your server
-
Deploy it (or just run it for fun and utility on your machine)
You’ve got the foundation. Just tell me what you want to do next, and we’ll build it together — one clear step at a time.
You said:
ChatGPT said:
YES — let’s take your server to the next level and have it control Blender to create 3D objects!
🧠 How It Works
You’ll use an MCP tool to run Blender in the background with a Python script that creates or modifies 3D models.
Here’s the game plan:
✅ What You’ll Need
-
Blender installed (which you already have)
-
The Blender executable path (like
C:\Program Files\Blender Foundation\Blender\blender.exe
) -
A script template to generate 3D shapes (like a cube or sphere)
-
An MCP tool to launch Blender with that script
🛠 Step-by-Step Setup
1. Find Blender's Path
Find where Blender is installed — most likely:
makefileC:\Program Files\Blender Foundation\Blender\blender.exe
Confirm it by navigating there in File Explorer.
2. Add a Tool to Your server.py
Open server.py
and add this:
pythonimport subprocess
@mcp.tool()
def create_blender_cube(output_path: str) -> str:
"""Creates a Blender scene with a cube"""

🧪 How to Test It
-
Restart your server:
cmdmcp dev server.py
-
Go to the MCP Inspector
-
Use the
create_blender_cube
tool and give it a file path like:makefileC:\\Users\\YourName\\Documents\\cube.blend
You’ll see a new .blend
file created — with a cube inside!
Would you like to try this now? I can help you adjust the Blender path or tweak the script to make other shapes too (like spheres or text).

Great question — and you're thinking about this exactly the right way.
🔍 What You’re Looking At: MCP Inspector UI
This web interface is the client side, not the server.
Here's how the pieces fit together:
Component | What it Does | Where You See It |
---|---|---|
MCP Server | Runs your tools/resources | Your server.py file (in terminal) |
MCP Inspector | Lets you test servers and tools | The web UI at http://127.0.0.1... |
🔌 Why It Says "Connect"
When it says:
“Connect”, “Add transport”, “Command arguments”, etc.
That means it's waiting for you to manually tell it:
-
Which file is your MCP server
-
How to launch it (via stdio or HTTP)
-
What arguments or env vars to use
But you already did that by running:
cmdmcp dev server.py
So if the Inspector is still saying “Connect,” here’s what might be happening:
✅ Step-by-Step Fix
-
Close all previous terminals
-
Open a new Command Prompt inside
mcp-test
-
Activate your environment:
cmdmcp-env\Scripts\activate
-
Run the dev command:
cmdmcp dev server.py
✅ That should auto-launch Inspector and connect it directly.
💡 Pro Tip
-
The
mcp dev
command starts the server and launches Inspector already connected -
If you try to launch Inspector manually (without
mcp dev
), you'll need to manually configure it — which is what you're seeing
Let me know what the terminal says after you run mcp dev server.py
— I can quickly help fix any connection hiccup.

No worries — that can happen! Here's how to shut down the running server or Inspector cleanly:
🛑 How to Stop a Running MCP Server (or Anything in Terminal)
✅ Option 1: Keyboard Shortcut
In the Command Prompt or PowerShell window where it’s running, press:
textCtrl + C
Hold the Ctrl
key and tap C
. This sends a "terminate" signal to the running process and is the standard way to stop any server or command-line app.
You should see a message like:
nginxKeyboardInterrupt
And the prompt should return to normal.
🔁 If That Doesn’t Work
Just close the Command Prompt window entirely:
-
Click the ❌ in the corner
-
Or type:
cmdexit
Then reopen a new one and start fresh.
Let me know once it's shut down and you're back in the prompt — and we’ll relaunch it cleanly with mcp dev server.py
