Illustrator MCP Server

An MCP (Model Context Protocol) server for reading, manipulating, and exporting Adobe Illustrator design data — with 63 built-in tools.

Control Illustrator directly from AI assistants like Claude — extract design information for web implementation, verify print-ready data, and export assets.

[!TIP] Developing and maintaining this tool takes time and resources. If it helps your workflow, your support means a lot — ☕ buy me a coffee!

🚀 Quick Start

🛠️ Claude Code

Requires Node.js 20+.

claude mcp add illustrator-mcp -- npx illustrator-mcp-server

🖥️ Claude Desktop

1. Download illustrator-mcp-server.mcpb from GitHub Releases
2. Open Claude Desktop → Settings → Extensions
3. Drag and drop the .mcpb file into the Extensions panel
4. Click the Install button

[!NOTE] The .mcpb extension does not auto-update. To update, download the new version and reinstall. If you prefer automatic updates, use the npx method below instead.

Requires Node.js 20+. Open the config file and add the connection settings.

1. Open the config file

From the Claude Desktop menu bar:

Claude → Settings... → Developer (in the left sidebar) → Click the Edit Config button

2. Add the settings

{
  "mcpServers": {
    "illustrator": {
      "command": "npx",
      "args": ["illustrator-mcp-server"]
    }
  }
}

[!NOTE] If you installed Node.js via a version manager (nvm, mise, fnm, etc.), Claude Desktop may not find npx. In that case, use the full path:

"command": "/full/path/to/npx"

Run which npx in your terminal to find the path.

3. Save and restart

1. Save the file and close the text editor
2. Fully quit Claude Desktop (⌘Q / Ctrl+Q) and reopen it

[!CAUTION] AI can make mistakes. Do not over-rely on the output — always have a human perform the final check on submission data. The user is responsible for the results.

[!NOTE] macOS: On first run, allow automation access in System Settings > Privacy & Security > Automation.

[!NOTE] Modify and export tools will bring Illustrator to the foreground during execution.

🎬 What You Can Do

You:    Show me all the text information in this document
Claude:  → list_text_frames → get_text_frame_detail
         There are 12 text frames in the document.
         The heading "My Design" uses Noto Sans JP Bold 48px, color #333333 ...

You:    Run a pre-press preflight check
Claude:  → preflight_check
         ⚠ 2 warnings:
         - Low resolution image: image_01.jpg (150dpi) — 300dpi or higher recommended
         - Non-outlined fonts: 3 text frames

You:    Check text for inconsistencies
Claude:  → check_text_consistency
         📝 Consistency Report:
         ⚠ "Contact Us" vs "Contact us" — capitalization mismatch
         ❌ "Lorem ipsum" (2 places) — placeholder text remaining

You:    Create banner size variations from this A4 flyer
Claude:  → get_document_info → resize_for_variation
         Created 3 size variations:
         - 728×90 / 300×250 / 160×600

📖 Recipes

You:    Summarize the colors and typography in this design

Claude:  → get_colors → list_text_frames → get_text_frame_detail

         ■ Color Palette
         - Primary: #1A73E8 (CMYK: 85,50,0,0)
         - Secondary: #34A853
         - Text: #202124
         - Background: #FFFFFF

         ■ Typography
         - Headings: Noto Sans JP Bold / 32px
         - Body: Noto Sans JP Regular / 16px / line-height: 1.75
         - Captions: Noto Sans JP Medium / 12px

You:    Export all artboards as SVG with outlined text

Claude:  → get_artboards → convert_to_outlines → export (repeated)

         Exported 4 artboards:
         - /output/header.svg
         - /output/hero.svg
         - /output/feature.svg
         - /output/footer.svg

You:    Check if this document is PDF/X-1a compliant

Claude:  → preflight_check (target_pdf_profile: "x1a")

         ❌ PDF/X-1a compliance errors:
         - Transparency on 3 objects (X-1a prohibits transparency)
         - RGB colors found in 2 places (X-1a requires CMYK/spot only)

         ⚠ Warnings:
         - 5 non-outlined fonts (embedding recommended)
         - Image "photo_02.jpg" at 150dpi (300dpi recommended)

You:    Check placed image quality for print

Claude:  → get_images (include_print_info: true)

         ■ Image Quality Report:
         ✅ hero.psd — CMYK, 350dpi, scale 98%
         ⚠ icon_set.png — RGB (mismatch with CMYK document), 300dpi, scale 100%
         ❌ photo_bg.jpg — CMYK, 72dpi, scale 400% (over-enlarged)
           → Replace with a 300dpi+ image at actual size

You:    Check text contrast ratios

Claude:  → check_contrast (auto_detect: true)

         ■ WCAG Contrast Report:
         ❌ "Caption" on "light gray" — 2.8:1 (AA fail)
         ⚠ "Subheading" on "white" — 4.2:1 (AA Large OK, AA Normal fail)
         ✅ "Body text" on "white" — 12.1:1 (AAA pass)

Testing

# Unit tests
npm test

# E2E smoke test (requires Illustrator running)
npx tsx test/e2e/smoke-test.ts

The E2E test creates a fresh document, places test objects, runs 106 test cases across 6 phases covering all registered tools, and cleans up automatically.

Disclaimer

This tool automates many Illustrator operations, but AI can make mistakes. Extracted data, preflight results, and document modifications should always be reviewed by a person. Do not rely on this tool as your sole quality check. Use it as an assistant alongside your own manual verification, especially for print submissions and client deliverables. The authors are not responsible for any damages or losses arising from the use of this software or its outputs.
