Restival

Restival is a Blender addon that exposes your scene as a live REST API. It lets local models, external tools, and AI agents inspect objects, meshes, and scene data over HTTP without touching Blender's UI.

I built it because small models can often understand REST APIs more reliably than complex local MCP setups. In Blender, MCP-based workflows can add friction, create stale connections, and raise security concerns when arbitrary Python execution is involved. Restival keeps things simple. It is one addon, read-only for now, and easy for most models to use.

Features

• Read-only REST API for live Blender scene data
• Works well with local models, tools, and AI agents
• Inspect scenes, objects, meshes, and file metadata over HTTP
• Generic bpy.data traversal for deeper inspection
• Simple setup inside Blender with no extra MCP-style wiring
• Built-in UI panel to start and stop the server
• Shows the active API URL and local IPs in the addon UI
• Copy-ready to use curl URL and agent prompt actions from the panel

Install

Blender 4.2 or newer is required.

1. Download this repo as a ZIP or package it as a Blender addon.
2. In Blender, go to Edit > Preferences > Add-ons.
3. Click Install from Disk and select the ZIP.
4. Enable Restival.

Use

1. Open Blender.
2. Go to View3D > Sidebar > Restival.
3. Set the port if needed. Default is 2357.
4. Leave Network Mode off for localhost only, or enable it to expose the API on your local network.
5. Click Start Server.

Base URL by default:

http://127.0.0.1:2357/api/v1

All endpoints are GET only.

Examples

curl -s http://127.0.0.1:2357/api/v1/health
curl -s http://127.0.0.1:2357/api/v1/scenes
curl -s http://127.0.0.1:2357/api/v1/scenes/Scene/objects
curl -s http://127.0.0.1:2357/api/v1/scenes/Scene/objects/Cube
curl -s http://127.0.0.1:2357/api/v1/scenes/Scene/objects/Cube/mesh
curl -s http://127.0.0.1:2357/api/v1/data/materials

If you want the API to describe itself first:

curl -s http://127.0.0.1:2357/api/v1
