Fan3D Agent Plugin

Create, inspect, edit, preview, validate, and render local Fan3D projects from Codex or WorkBuddy. Both hosts load the same Fan3D Skills and start the same local stdio MCP server; all project mutations and rendering remain owned by the native Fan3D application.

Requirements

• macOS with Fan3D.app installed at /Applications/Fan3D.app.
• A supported Agent host with the Fan3D plugin installed and enabled.
• Fan3D authentication and resource access when a requested operation requires them. Agent-host credentials never replace Fan3D authorization.

WorkBuddy

Add the 7757/fan3d-agent-plugin GitHub repository as a third-party WorkBuddy marketplace, install fan3d@fan3d, and start a new conversation after installation or update. WorkBuddy discovers the shared Skills and starts the bundled fan3d MCP entry automatically.

For local development, load the repository copy without installing it:

codebuddy --plugin-dir /absolute/path/to/Plugins/fan3d

The development command does not replace the normal marketplace installation flow used by released versions.

Usage

Ask the Agent to create a product introduction, list or inspect Fan3D projects, edit a project, render a preview, validate a scene, or submit a final output. The Agent must use the connected server's live tool catalog and follow the Revision, idempotency, authorization, cancellation, and verification rules in the packaged Skills.

The plugin does not bundle a model, Agent loop, model credentials, or a copy of Fan3D. It only connects the host to the signed local Helper shipped inside the installed Fan3D app.
