RenderBuddy MCP — AI-Connected Render Agent & Gateway

"Your Blender render, one message away."
Version: v3.0.1 | Status: Production Ready | Tests: 59/59 Passed (100%)

🎨 What is RenderBuddy?

RenderBuddy is an open-source, AI-connected render agent and gateway platform for Blender 3.6+ and 5.1+. It allows 3D artists, studio teams, and developers to monitor and control long Blender render jobs using natural language — via AI assistants (Antigravity, Claude, Cursor), a real-time Web Dashboard, or a Telegram Mobile Bot.

✨ Features at a Glance

• 🟢 Native Blender Add-on (v3.0.1): Runs inside Blender with @persistent render handlers and an N-Panel control panel.

• 🤖 MCP Server (8 Tools): Exposes status, frame preview, settings, email dispatch, local upload, render cancellation, and system shutdown tools to AI clients over stdio.

• 📊 Glassmorphism Web Dashboard: Live telemetry monitoring completion percentage, frame count, elapsed time, and engine stats in real time.

• 📱 Telegram Bot Integration: Monitor progress, request live frame previews (/preview), or cancel renders (/cancel <PIN>) directly from your phone.

• 🔒 PIN Security Gate: Destructive actions (render cancellation and system shutdown) are protected by salted SHA-256 PIN authentication.

• 🚀 Zero Cloud Dependency: Pure Python core (stdlib + MCP SDK). No subscription services required.

🏛️ System Architecture & Gateway Hierarchy

RenderBuddy operates on a decoupled 3-tier architecture:

Workstation (Blender + Add-on)
    └─ Loopback TCP (Port 7345) ──► Local Agent (SQLite DB + REST API 7342)
                                        │
                                        ▼
                               Gateway Runner (runner.py)
                                ├── API Interface (Agent HTTP 7342 proxy)
                                ├── Web Dashboard (web_ui.py - Port 8080)
                                ├── Telegram Bot (telegram_bot.py)
                                └── Pairing Service (pairing.py - OTP Manager)
                                        │
                                        ▼
                               Public Internet / Remote Clients
                                (Mobile Web UI / Telegram / MCP / ChatGPT)

🚀 Quick Start Guide

1. Build & Install the Blender Add-on

python build_addon.py

In Blender: Edit → Preferences → Add-ons → Install from Disk... → Select dist/renderbuddy_addon.zip and enable RenderBuddy.

2. Configure MCP Client

Add RenderBuddy to your MCP client configuration (mcp_config.json):

{

      "command": "python",
      "args": [
        "D:/MCP_RenderBuddy/main.py"
      ]
    }
  }
}

3. Launch Gateway Services

python -m gateway.runner
