# InDesign UXP MCP Server

> **Forked from** [zachshallbetter/indesign-mcp-server](https://github.com/zachshallbetter/indesign-mcp-server) — rewritten to use Adobe's UXP plugin platform instead of AppleScript.

A Model Context Protocol (MCP) server that gives AI assistants direct, native control over Adobe InDesign via a UXP plugin bridge. ~130 tools covering the full InDesign feature set — documents, pages, text, graphics, styles, master spreads, books, and export.

---

## Why UXP vs AppleScript

This server is a ground-up rewrite of the AppleScript-based [indesign-mcp-server](https://github.com/zachshallbetter/indesign-mcp-server). The execution model is fundamentally different.

| | AppleScript (original) | UXP (this fork) |
|---|---|---|
| **Platform** | macOS only | macOS + Windows |
| **Execution path** | Node → temp JSX file → AppleScript → InDesign | Node → HTTP → WebSocket → InDesign plugin |
| **Speed** | Slow — 3 hops, disk write per call | Fast — direct in-process call |
| **Reliability** | Flaky — breaks if InDesign loses focus or system dialogs appear | Stable — not affected by focus or system state |
| **Return values** | Strings only (last evaluated expression) | Full structured JSON objects |
| **JS version** | ExtendScript (ES3 — no `const`, arrow functions, or `async/await`) | Modern JS (ES2015+ — `async/await`, destructuring, arrow functions) |
| **Error messages** | Cryptic AppleScript/OSA errors | Structured JSON with clear error strings |
| **String handling** | Manual `escapeJsxString()` for every value | `JSON.stringify()` throughout — safe and simple |
| **Enums** | Magic strings like `'PDF_TYPE'` | Typed enums via `require('indesign').ExportFormat.pdfType` |
| **Async support** | Not supported — synchronous only | Native `await` (e.g. `await doc.filePath`) |
| **Permissions** | macOS Automation + Accessibility in System Settings | None beyond InDesign plugin install |
| **Future-proofing** | ❌ Adobe is deprecating ExtendScript/CEP | ✅ UXP is Adobe's official modern platform |

**The short version**: The AppleScript version puppets InDesign from the outside via macOS automation, writing temp files and hoping nothing interrupts the chain. This version runs _inside_ InDesign as a first-class plugin — faster, more reliable, cross-platform, and built on the platform Adobe is investing in going forward.

## How It Works

```
Claude / MCP Client
       │
       ▼
  MCP Server (Node.js)
       │  POST /execute
       ▼
  Bridge HTTP Server (port 3000)
       │  WebSocket
       ▼
  UXP Plugin (inside InDesign)
       │  runs as async IIFE with `app` in scope
       ▼
  InDesign DOM
```

The UXP plugin maintains a persistent WebSocket connection to the bridge. When a tool is called, the handler sends a JS code string to the bridge, which forwards it to the plugin. The plugin runs it as `new Function('app', 'return (async () => { CODE })()')` and returns the result as JSON.

---

## Prerequisites

- Adobe InDesign 2024+ (UXP plugin support required)
- Node.js 18+
- macOS or Windows

---

## Setup

### 1. Install the UXP Plugin

Load the plugin via the UXP Developer Tool or InDesign's plugin manager:

```
plugin/
├── index.js        # Plugin entry point + WebSocket client
└── manifest.json   # Plugin manifest
```

### 2. Start the Bridge

```bash
# Kill any existing bridge processes
lsof -ti:3001 | xargs kill 2>/dev/null
lsof -ti:3000 | xargs kill 2>/dev/null

# Start the bridge
cd bridge && node server.js
```

### 3. Connect the Plugin

In InDesign: **Window → Plugins → InDesign Bridge**

The panel should show: `Connected to bridge ✓`

### 4. Start the MCP Server

```bash
npm install
npm start
```

### 5. Configure Claude

Add to `~/.claude.json` (or your MCP client config):

```json
{
  "mcpServers": {
    "indesign": {
      "command": "node",
      "args": ["/path/to/indesign-uxp-server/src/index.js"]
    }
  }
}
```

---

## Testing

```bash
# Quick sanity check (4 core tools)
node tests/test-uxp-handlers.js

# Full suite (27 tests across all handler categories)
node tests/test-all-handlers.js
```

Current status: **27/27 passing** across all handler categories.

### Key UXP API Notes

- InDesign collections require `.item(n)` — bracket access `[n]` returns undefined
- `doc.filePath` is async — always `await` it in UXP code
- `exportFile(format, path)` — format arg is **first** (same as ExtendScript)
- Enums via `require('indesign')`: `ExportFormat.pdfType`, `ColorModel.process`, etc.
- Path strings work directly for `place()` and `exportFile()` — no UXP storage API needed
- Code runs as `async IIFE` — use `return` to return values, `await` works natively
