### Description (declared)

# klayout-draw-mcp

An [MCP](https://modelcontextprotocol.io) server for **drawing GDS layouts** with **KLayout** — generate, edit, and view layouts from an AI assistant such as Claude Code or Claude Desktop.

Layout geometry is built in-process with the standalone [`klayout`](https://pypi.org/project/klayout/) Python module (no GUI needed). The installed KLayout application is launched only for viewing or manual editing.

## Tools

| Tool | Purpose |
| --- | --- |
| `new_layout(top_cell, dbu)` | Start a new in-memory layout (coordinates in micrometers) |
| `add_box(layer, x1, y1, x2, y2, datatype)` | Add a rectangle |
| `add_polygon(layer, points, datatype)` | Add a polygon from `[x, y]` vertices |
| `add_path(layer, points, width, datatype)` | Add a path with width |
| `add_label(layer, x, y, text, datatype)` | Add a text label |
| `create_cell(name)` / `use_cell(name)` | Create/select the active drawing cell |
| `place_cell(cell, x, y, orient, nx, ny, dx, dy)` | Place an instance or array of a cell |
| `add_via(x, y, bottom_layer, top_layer, cut_layer, …)` | Via: cut array + enclosing metal |
| `add_wire(layer, points, width)` | Manhattan wire (auto L-corners) |
| `layout_info()` | Inspect current layout (layers, bbox, shape count) |
| `load_gds(path, top_cell?)` | Load an existing GDS/OASIS into the session for editing |
| `inspect_gds(path?)` | Per-layer shape count, area and bbox of a file or the session |
| `drc_check(rules, path?)` | Simple DRC: spacing / width / overlap / separation / enclosure |
| `save_gds(path, open_after)` | Write GDS/OASIS; optionally open in the editor |
| `open_layout(file_path)` | Open a file in KLayout (viewer) |
| `open_editor(file_path?)` | Open KLayout in editor mode, or a blank layout |
| `run_script(code)` | Run arbitrary Python with `klayout.db` (cell hierarchy, arrays, booleans, DRC, ...) |
