henn-mcp-openwebui-relay

Rhino plugin · v0.5.6 · updated 11/10/2026

New

An independent prototype, not a McNeel or Open WebUI product. It exposes the whole RhinoAI toolbox (arbitrary scripting and filesystem access with your own Windows permissions) with no sandbox and no per-call approval. Read the guide before using it. Every command begins with OpenWebUIRelay. _OpenWebUIRelayToolbar puts the toolbar on screen. _OpenWebUIRelayLink opens the main window. _OpenWebUIRelaySettings opens the settings. _OpenWebUIRelayMonitor shows live status and the launch log. _OpenWebUIRelayHelp opens the online guide. _OpenWebUIRelayToggle starts or stops the link without opening a window. _OpenWebUIRelayUnlink stops the router process tree. Exposes a local Rhino session to Open WebUI as an OpenAPI tool server by relaying McNeel's RhinoAI MCP router. Start and stop the bridge from inside Rhino, and the plugin can write the tool-server entry into your Open WebUI settings for you. MIT licensed. Questions and bug reports to et@henn.com.
