Client sends a tool request via MCP protocol 2. Server identifies the appropriate category and script 3. Script content is generated (static or dynamically via function) 4. AppleScript is executed via macOS `osascript` command 5. 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 ```bash # 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`: ```typescript import { ScriptCategory } from "../types/index.js"; export const newCategory: ScriptCategory = { name: "category_name", description: "Category description", scripts: [ // Scripts will go here ], }; ``` #### 2. Add Scripts ```typescript { 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 ${args.paramName} end tell ` } ``` #### 3. Register Category Update `src/index.ts`: ```typescript import { newCategory } from "./categories/newcategory.js"; // ... server.addCategory(newCategory); ``` ### Advanced Script Development For more complex scripts, you can: 1. **Use dynamic script generation**: ```typescript script: (args) => { // Process arguments and build script dynamically let scriptContent = `tell application "App"\n`; if (args.condition) { scriptContent += ` // Conditional logic\n`; } scriptContent += `end tell`; return scriptContent; } ``` 2. **Process complex data**: ```typescript // Example from Notes category function generateNoteHtml(args: any): string { // Process markdown-like syntax into HTML let processedContent = content; if (format.headings) { processedContent = processedContent.replace(/^# (.+)$/gm, '

$1

'); // ... } return processedContent; } ``` ## Debugging ### Using MCP Inspector The MCP Inspector provides a web interface for testing and debugging your server: ```bash npm run inspector ``` ### Logging Enable debug logging by setting the environment variable: ```bash DEBUG=applescript-mcp* npm start ``` ### Example configuration After running `npm run build` add the following to your `mcp.json` file: ```json { "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 ## Resources - [AppleScript Language Guide](https://developer.apple.com/library/archive/documentation/AppleScript/Conceptual/AppleScriptLangGuide/introduction/ASLR_intro.html) - [MCP Protocol Documentation](https://modelcontextprotocol.io) - [Issue Tracker](https://github.com/joshrutkowski/applescript-mcp/issues) ## Contributing 1.
