Keynote MCP Server

A Model Context Protocol (MCP) server that provides full programmatic control over Apple Keynote through AppleScript and JXA (JavaScript for Automation). Designed for use with Claude Desktop and any MCP-compatible client, this server lets you create, edit, present, and export Keynote presentations entirely through natural language.

Prerequisites

• macOS (any recent version with Keynote installed)
• Apple Keynote (free from the Mac App Store)
• Node.js 18+ (check with node --version)
• Accessibility permissions -- your terminal or IDE must be allowed to control Keynote via System Settings > Privacy & Security > Accessibility

Installation

git clone https://github.com/superdwayne/keynoteMP.git keynote-mcp-server
cd keynote-mcp-server
npm install
npm run build

Verify the build succeeds and types pass:

npx tsc --noEmit

Claude Desktop Configuration

Add the following entry to your claude_desktop_config.json (typically located at ~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "keynote": {
      "command": "node",
      "args": ["/absolute/path/to/keynote-mcp-server/dist/index.js"]
    }
  }
}

Replace /absolute/path/to/keynote-mcp-server with the actual path on your machine. Restart Claude Desktop after saving the configuration.

Usage Examples

Design a pitch deck from a template

"Create a pitch deck for my startup using the pitch-deck template with our brand colors #2563EB and an elegant style."

Claude will call set_brand, then design_from_template with "pitch-deck", generating all 10 slides with coordinated layouts, typography, and transitions.

Design a single slide with brand-aware styling

"Design slide 3 with the title 'Market Opportunity', body text about the TAM, and use the statistic layout."

Claude will call design_slide with the content and layout name, automatically applying brand colors and typography.

Create a presentation from scratch

"Create a new Keynote presentation with the Gradient theme, add 5 slides, and set titles for each one."

Claude will call create_presentation, then add_slide five times, and set_slide_title for each slide.

Build a data-driven slide

"On slide 3, add a table with quarterly revenue data: Q1: $1.2M, Q2: $1.5M, Q3: $1.8M, Q4: $2.1M."

Claude will use add_table, then set_table_data to populate the cells.

Export for sharing

"Export my presentation as a PDF to the Desktop and also save each slide as a PNG image."

Claude will call export_to_pdf and export_to_images with the appropriate paths.

Add brand-aware text and shapes

"Add a heading with role 'display' on slide 1 that says 'Welcome'."

Claude will call add_text_item with role: "display", which automatically applies brand-aware font, size, and color with WCAG-compliant contrast.

The server uses stdio transport (standard for local MCP servers). Each tool module exports a register*Tools(server) function that registers tools with the MCP server instance. All Keynote automation is performed by shelling out to osascript via child_process.execFile, using either AppleScript or JXA depending on the operation.

Troubleshooting

"AppleScript error: Not authorized to send Apple events"

Your terminal or IDE needs Accessibility permissions. Go to System Settings > Privacy & Security > Accessibility and add your terminal application (Terminal.app, iTerm2, VS Code, etc.).

You may also need to grant permissions under Privacy & Security > Automation to allow your terminal to control Keynote.

"Keynote got an error: Can't get document 1"

No Keynote presentation is currently open. Use create_presentation or open_presentation first.

Build errors

Make sure you have Node.js 18+ installed and run npm install before npm run build. The project requires TypeScript and the MCP SDK as dependencies.

Keynote must be installed

This server controls Keynote.app via AppleScript. It will not work without Keynote installed. Keynote is free from the Mac App Store.

Chart creation limitations

Direct chart creation via AppleScript is limited in some Keynote versions. The add_chart tool will attempt to create a chart directly but may fall back to creating a data table with your values. You can then manually convert that table to a chart in Keynote.

Timeout errors

Each AppleScript command has a 30-second timeout. Operations on very large presentations or complex exports may occasionally time out. If this happens, try the operation again or work with fewer slides at a time.
