### Description (declared)

# sketchpad-mcp

[![CI](https://github.com/kennycornellius-collab/sketchpad-mcp/actions/workflows/ci.yml/badge.svg)](https://github.com/kennycornellius-collab/sketchpad-mcp/actions/workflows/ci.yml)

A visual input tool for AI coding agents. You sketch; the agent reads the sketch.

Most MCP drawing tools go **agent → human** (the agent generates a diagram for you to view). This one goes the other way: **human → agent**. Open a canvas, draw your idea, and the resulting image lands directly in the agent's context.

---

## How it works

1. The agent calls `open_canvas` (or you ask it to: *"open the canvas, I want to sketch this"*)
2. A drawing tab opens in your default browser — powered by [Excalidraw](https://excalidraw.com/)
3. You sketch, paste, or annotate
4. Click **Send to Claude** — the PNG is returned directly to the agent
5. The tab stays open; the agent can call the tool again and your drawing is still there to refine

---

## Requirements

- Python 3.10+
- Claude Code (CLI)

---

## Installation

**1. Clone and install dependencies**

```bash
git clone https://github.com/kennycornellius-collab/sketchpad-mcp.git
cd sketchpad-mcp
pip install -e .
```

**2. Register with Claude Code**

```bash
claude mcp add sketchpad --transport stdio --scope user -- python -m sketchpad_mcp
```

Use the `python` from the environment where you ran `pip install` (e.g. the absolute path to your venv's `python`). Alternatively, the install provides a `sketchpad-mcp` console command you can register instead of `python -m sketchpad_mcp`.

**3. Verify it's registered**

```bash
claude mcp list
```

You should see `sketchpad` in the list.

---

## Usage

Once registered, the tools are available in any Claude Code session.

**Let the agent decide** — Claude Code will open the canvas on its own when your description is ambiguous or visual.

**Ask explicitly:**

> "Open the canvas, I want to sketch the layout."

> "Draw me a rough wireframe and send it over."

The canvas tab stays aliv…
