## Overview

`rhino-mcp` is a Model Context Protocol server that lets Claude (or any MCP client) drive Rhino 8 — creating geometry, manipulating layers and materials, baking Grasshopper output, exporting STEP/IGES/STL/OBJ — through plain natural-language tool calls.
It runs in two modes:

- **Standalone** (default): backed by [`rhino3dm`](https://github.com/mcneel/rhino3dm) for headless `.3dm` file authoring; works without Rhino installed and exposes **~242 tools** (geometry, file-I/O, transform, layer, material, analysis, RhinoScript docs, composition, document hygiene, geometry validation, GH template catalogue, freeform skin / panelisation / curvature / fields, drawing-set sheet + title block, schedule / quantity, block definition, sun-position + shadow projection, BIM metadata tagging, 19 physical material presets, BRE daylight factor + Bird DNI clear-sky model, and multi-Rhino announcement-file discovery).
- **Bridge**: when the C# bridge plugin is loaded in a live Rhino 8 session, the server transparently forwards every call (booleans, lofts, sweeps, viewport image capture + zoom-to-object / zoom-to-layer, render, scripting (Python and gated Roslyn C# with timeouts and extra references), deformation, NURBS editing, SubD, paneling, freeform analysis with true Gaussian curvature, drawing-s…
