Architecture

The applescript-mcp server is built using TypeScript and follows a modular architecture:

Core Components

AppleScriptFramework (framework.ts): The main server class that:
- Manages MCP protocol communication
- Handles tool registration and execution
- Provides logging functionality
- Executes AppleScript commands
Categories (src/categories/*.ts): Modular script collections organized by functionality:
- Each category contains related scripts (e.g., calendar, system, notes)
- Categories are registered with the framework in index.ts
Types (src/types/index.ts): TypeScript interfaces defining:
- ScriptDefinition: Structure for individual scripts
- ScriptCategory: Collection of related scripts
- LogLevel: Standard logging levels
- FrameworkOptions: Configuration options

Execution Flow

Client sends a tool request via MCP protocol
Server identifies the appropriate category and script
Script content is generated (static or dynamically via function)
AppleScript is executed via macOS osascript command
Results are returned to the client

Logging System

The framework includes a comprehensive logging system that:

Logs to both stderr and MCP logging protocol
Supports multiple severity levels (debug, info, warning, error, etc.)
Provides detailed execution information for troubleshooting

Development

Setup

# Install dependencies
npm install

# Build the server
npm run build

# Launch MCP Inspector
# See: https://modelcontextprotocol.io/docs/tools/inspector
npx @modelcontextprotocol/inspector node path/to/server/index.js args...

Adding New Functionality

1. Create Category File

Create src/categories/newcategory.ts:

import { ScriptCategory } from "../types/index.js";

export const newCategory: ScriptCategory = {
  name: "category_name",
  description: "Category description",
  scripts: [
    // Scripts will go here
  ],
};

2. Add Scripts

{
  name: "script_name",
  description: "What the script does",
  schema: {
    type: "object",
    properties: {
      paramName: {
        type: "string",
        description: "Parameter description"
      }
    },
    required: ["paramName"]
  },
  script: (args) => `
    tell application "App"
      // AppleScript code using ${args.paramName}
    end tell
  `
}

3. Register Category

Update src/index.ts:

import { newCategory } from "./categories/newcategory.js";
// ...
server.addCategory(newCategory);

Advanced Script Development

For more complex scripts, you can:

Use dynamic script generation:

script: (args) => {
  // Process arguments and build script dynamically
  let scriptContent = `tell application "App"\n`;
  
  if (args.condition) {
    scriptContent += `  // Conditional logic\n`;
  }
  
  scriptContent += `end tell`;
  return scriptContent;
}

Process complex data:

// Example from Notes category
function generateNoteHtml(args: any): string {
  // Process markdown-like syntax into HTML
  let processedContent = content;
  
  if (format.headings) {
    processedContent = processedContent.replace(/^# (.+)$/gm, '<h1>$1</h1>');
    // ...
  }
  
  return processedContent;
}

Debugging

Using MCP Inspector

The MCP Inspector provides a web interface for testing and debugging your server:

npm run inspector

Logging

Enable debug logging by setting the environment variable:

DEBUG=applescript-mcp* npm start

Example configuration

After running npm run build add the following to your mcp.json file:

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

Common Issues

Permission Errors: Check System Preferences > Security & Privacy > Privacy > Automation
Script Failures: Test scripts directly in Script Editor.app before integration
Communication Issues: Check stdio streams aren't being redirected
Database Access: Some features (like Messages) require Full Disk Access permission
