Trellis MCP Server

Trellis MCP provides an interface between AI assistants and Trellis via Model Context Protocol (MCP).

Disclaimer

This project shows a very minimal integration of MCP with Trellis: a lightweight and opensource text-to-3d/image-to-3d 3DAIGC model. Compared with existing rodin integration in blender-mcp and tripo integration, it has following advantages:

• Faster and memory-efficient: You can deploy TRELLIS locally with only 8GPU+ VRAM, while can generate a textured mesh from text in only ~15s(10s with more vram).
• FREE: You DON'T have to pay expensive API from Rodin/Meshy/Tripo.

BUT IT HAS FOLLOWING LIMITATIONS:

• Trellis is open-source and there is no off-the-shelf API model providers, you have to deploy it by yourself (refer to README).
• The API/Prompt has NOT been fully tested/tuned, may suffer from stability issues.

So use it at your own risk.

Demo

A minimal demo for generating a single object, more complicated prompt with blender-mcp is under tuning.

Features

• [x] Generate 3D asset from natural language(TEXT) using Trellis API and import into blender
• [ ] Generate texture/materials from natural language(TEXT) for a given 3D mesh using Trellis API and import into blender

Roadmap

Prerequisites

• Python 3.10+
• Blender
• Trellis Blender Addon
• Trellis API Backend
• Claude / Cursor(SUGGESTED) / Windsurf

Installation

1. Trellis blender addon

1. Download Trellis Blender Addon from here
2. Open Blender -> Edit -> Preferences -> Add-ons -> Install from file -> Select the downloaded addon -> Install
3. In 3D Viewport -> View3D > Sidebar > TRELLIS -> Start MCP Server

2. Configure API backend

As trellis is a free open-source text-to-3d model, you need to deploy your own trellis API backend with reference to README

# clone an API fork of trellis 
git clone https://github.com/FishWoWater/TRELLIS
cd TRELLIS

# EDIT BACKEND URL in trellis_api/config.py

# configure the # of text workers and start ai worker
# no need for image workers 
python trellis_api/ai_worker.py --text-workers-per-gpu 1 --image-workers-per-gpu 0

# start web server 
python trellis_api/web_server.py 

# or on windows local dev 
python trellis_api/web_server_single.py 

3. Configure the MCP server on Windsurf/Cursor/Claude
