### Description (declared)

# textual-mcp-server

An [MCP](https://modelcontextprotocol.io) server that lets AI agents launch, interact with, and inspect [Textual](https://textual.textualize.io) TUI applications headlessly. Drive any Textual app through its full lifecycle — click buttons, type text, read widget state, take screenshots — all via the Model Context Protocol.

## Features

- **Headless app execution** — Launch any Textual app without a terminal, powered by Textual's built-in `Pilot` testing API
- **Full interaction toolkit** — Click, type, press keys, and hover over widgets using CSS selectors
- **Rich state inspection** — Snapshot the widget tree, query widgets by selector, and extract type-specific properties from 16+ widget types
- **Multi-session support** — Run multiple apps concurrently with isolated sessions
- **Error tracking** — Automatic collection of worker errors and app exceptions via message hooks
- **Screenshot capture** — Export the current screen as plain text or SVG

## Installation

Requires Python 3.10+.

```bash
pip install textual-mcp-server
```

For development:

```bash
git clone https://github.com/discohead/textual-mcp-server.git
cd textual-mcp-server
pip install -e ".[dev]"
```

## Quick Start

### As a standalone server

```bash
textual-mcp
```

### With Claude Code

Add to your MCP configuration (e.g., `~/.claude.json` or project `.mcp.json`):

```json
{
  "mcpServers": {
    "textual": {
      "command": "textual-mcp"
    }
  }
}
```

### Typical workflow

```
1. textual_launch("my_app.py")         → session_id
2. textual_snapshot(session_id)         → widget tree + focus + bindings
3. textual_click(session_id, "#submit") → interact
4. textual_screenshot(session_id)       → visual output
5. textual_stop(session_id)             → cleanup
```
