idml-mcp

idml-mcp

MCP server that lets AI agents read and safely edit Adobe InDesign files (IDML) — no InDesign required.

Unlike MCP servers that remote-control a running InDesign instance, idml-mcp works directly on .idml files via idmlkit. It runs anywhere Node.js runs — servers, CI, Linux — with nothing from Adobe installed, and its write-back preserves everything it doesn't touch byte-for-byte.

Setup (Claude Code / Claude Desktop)

{
  "mcpServers": {
    "idml": {
      "command": "npx",
      "args": ["-y", "idml-mcp"]
    }
  }
}

Tools

Tool	Purpose
idml_summarize	Structured summary of pages, frames, stories, images, styles
idml_get_story	One story's plain text + indexed runs with styles
idml_set_text	Replace one run's text (layout untouched, byte-for-byte)
idml_relink_image	Point an image link at a new file (geometry untouched)

Then ask Claude things like "Summarize catalog.idml and replace every 2025 date with 2026."
