3D Modeling (3D-Agent)
Control Blender with natural language. Create 3D models, modify scenes, and export assets — all by describing what you want.

TL;DR — MCP Servers Explained
An MCP server acts as a bridge between AI assistants (like Claude) and external applications. It translates AI commands into actions the application understands. 3D-Agent uses MCP to let you control Blender with natural language — no coding required.

Model Context Protocol
Purpose
Connect AI to external apps
Example

What is an MCP Server?
An MCP server is a program that implements the Model Context Protocol — a standard way for AI assistants to communicate with external applications. Think of it as a translator that sits between an AI (like Claude or Cursor) and software you want to control (like Blender, databases, or file systems).
Before MCP, connecting AI to external tools required custom integrations for each combination. MCP standardizes this, making it easier for developers to create AI-powered tools and for users to benefit from them.
The most exciting application? Using MCP to control creative software like Blender. With 3D-Agent, you can describe what you want in plain English, and the AI creates 3D models directly in your Blender scene.

How MCP Servers Work
MCP follows a simple client-server architecture. Here's how an AI assistant uses MCP to control an application:
1
You Give a Command
You tell the AI what you want in natural language: "Create a low-poly tree" or "Query the database for recent orders."
2
AI Sends MCP Request
The AI assistant (the MCP client) translates your request into a structured MCP command and sends it to the MCP server.
3
MCP Server Executes
The MCP server receives the command, translates it into actions the application understands, and executes them (e.g., creating geometry in Blender).
4
Results Return to AI
The MCP server sends results back to the AI, which can then respond to you or take further actions based on what happened.
Where MCP Servers Are Used
MCP servers enable AI control across many different applications. Here are the most common use cases:
File Systems
Let AI read, write, and organize files on your computer. Automate file management tasks with simple commands.
"Organize my downloads folder by file type"
Databases
Query and modify databases using natural language instead of SQL. Great for non-technical users who need data access.
"Show me all customers who signed up last month"
Web Browsers
AI can navigate websites, fill forms, and extract information. Useful for automation and research tasks.
"Find the pricing page and summarize the plans"
Code Editors
AI assistants like Cursor use MCP to understand your codebase and make intelligent edits across multiple files.
"Refactor this function to use async/await"
How 3D-Agent Uses MCP for Blender
3D-Agent is an MCP server specifically designed for Blender. It connects AI assistants to Blender's powerful 3D creation tools, letting you generate production-ready 3D models using natural language.
When you describe what you want ("Create a wooden barrel"), the AI sends commands through MCP to 3D-Agent. 3D-Agent then uses Blender's native modeling operations to create the asset — ensuring clean topology suitable for animation and games.
Unlike web-based AI 3D generators that produce messy meshes requiring cleanup, 3D-Agent works directly inside Blender. Your models are created with proper edge flow, quad-based geometry, and optimal polygon counts from the start.
—Native Blender integration — no export/import
—Clean topology ready for production
—Natural language control
—Works with Claude, Cursor, and other MCP clients

Frequently Asked Questions
What does MCP stand for?
▼
MCP stands for Model Context Protocol. It's an open standard developed by Anthropic that enables AI assistants to communicate with external applications in a standardized way.
What is an MCP server used for?
▼
An MCP server connects AI assistants to external applications. It translates AI commands into actions the application can execute. For example, 3D-Agent is an MCP server that lets AI control Blender for 3D modeling.
How does MCP work with AI assistants?
▼
The AI assistant acts as an MCP client. When you give a command, the AI sends a structured request to the MCP server, which executes the action in the target application and returns results back to the AI.
Is MCP the same as an API?
▼
MCP is built on top of standard protocols but adds a layer specifically designed for AI communication. Unlike traditional APIs, MCP includes features like tool discovery, context sharing, and standardized error handling that make AI integration easier.
What is 3D-Agent MCP?
▼
3D-Agent is an MCP server for Blender. It lets AI assistants like Claude create and modify 3D models in Blender using natural language commands. You describe what you want, and 3D-Agent generates production-ready 3D assets.
Do I need to know how to code to use MCP?
▼
No! That's the beauty of MCP. You interact with the AI in plain English, and the MCP server handles all the technical translation. With 3D-Agent, you just describe the 3D model you want — no Blender expertise or coding required.
