PocketBase MCP Server

# PocketBase MCP Server Refactoring Plan ## Overview Refactor the monolithic 1780-line `index.ts` file into a modular, maintainable codebase with proper separation of concerns. ## Project Structure (IMPLEMENTED) ``` src/ ├── index.ts # Entry point (24 lines - simplified) ├── server.ts # Main MCP server implementation ├── config/ │ ├── cli.ts # Command line argument parsing │ ├── environment.ts # Environment variable handling │ └── index.ts # Unified configuration interface ├── tools/ │ ├── index.ts # Tool registry and exports │ ├── schemas/ # Tool input schemas │ │ ├── analysis.ts # Analysis tool schemas │ │ ├── auth.ts # Authentication tool schemas │ │ ├── collection.ts # Collection tool schemas │ │ ├── generation.ts # Generation tool schemas │ │ ├── migration.ts # Migration tool schemas │ │ └── record.ts # Record tool schemas │ └── handlers/ # Tool implementation handlers │ ├── analysis.ts # Data analysis tools │ ├── auth.ts # Authentication operations │ ├── collection.ts # Collection CRUD operations │ ├── generation.ts # Code generation tools │ ├── migration.ts # Migration and backup tools │ └── record.ts # Record CRUD operations ├── utils/ │ ├── errors.ts # Error handling utilities │ ├── response.ts # Response formatting utilities │ └── typescript.ts # TypeScript parsing utilities └── types/ ├── index.ts # Common type definitions └── pocketbase.d.ts # PocketBase type extensions ``` ## Refactoring Checklist (COMPLETED) ### Phase 1: Foundation Setup ✅ - [x] Create directory structure - [x] Extract type definitions to `types/index.ts` - [x] Move PocketBase type extensions to proper location - [x] Create base interfaces for handlers and tools ### Phase 2: Configuration Extraction ✅ - [x] Extract CLI argument parsing to `config/cli.ts` - [x] Extract environment variable handling to `config/environment.ts` - [x] Create unified configuration interface - [x] Update main server to use new config modules ### Phase 3: Tool Schema Separation ✅ - [x] Extract collection tool schemas to `tools/schemas/collection.ts` - [x] Extract record tool schemas to `tools/schemas/record.ts` - [x] Extract auth tool schemas to `tools/schemas/auth.ts` - [x] Extract analysis tool schemas to `tools/schemas/analysis.ts` - [x] Extract migration tool schemas to `tools/schemas/migration.ts` - [x] Extract generation tool schemas to `tools/schemas/generation.ts` - [x] Create tool registry in `tools/index.ts` ### Phase 4: Handler Implementation ✅ - [x] Create base handler interface - [x] Implement collection handlers in `tools/handlers/collection.ts` - [x] `createCollection` - [x] `deleteCollection` - [x] `getCollectionSchema` - [x] Implement record handlers in `tools/handlers/record.ts` - [x] `createRecord` - [x] `listRecords` - [x] `updateRecord` - [x] `deleteRecord` - [x] Implement auth handlers in `tools/handlers/auth.ts` - [x] `authenticateUser` - [x] `createUser` - [x] Implement analysis handlers in `tools/handlers/analysis.ts` - [x] `analyzeCollectionData` - [x] `queryCollection` - [x] Implement migration handlers in `tools/handlers/migration.ts` - [x] `migrateCollection` - [x] `backupDatabase` - [x] `importData` - [x] `manageIndexes` - [x] Implement generation handlers in `tools/handlers/generation.ts` - [x] `generatePbSchema` - [x] `generateTypescriptInterfaces` ### Phase 5: Utility Extraction ✅ - [x] Create error handling utilities in `utils/errors.ts` - [x] Create response formatting utilities in `utils/response.ts` - [x] Extract TypeScript parsing logic to `utils/typescript.ts` - [x] Update handlers to use utility functions ### Phase 6: Server Simplification ✅ - [x] Create unified server implementation in `server.ts` - [x] Update main server to use handler pattern - [x] Implement proper dependency injection for PocketBase client - [x] Integrate MCP SDK properly with tool handlers ### Phase 7: Entry Point Cleanup ✅ - [x] Simplify `index.ts` to focus on initialization (reduced to 24 lines) - [x] Remove all business logic from entry point - [x] Ensure proper error handling and logging ### Phase 8: Testing & Validation ✅ - [x] Validate all existing functionality still works - [x] Test error handling scenarios - [x] Fix all TypeScript compilation errors - [x] Resolve all diagnostic issues ### Phase 9: Documentation & Cleanup ✅ - [x] Ensure consistent code style across all files - [x] Remove any unused code or dependencies - [x] Fix all linting and type safety issues ## Success Criteria ✅ - [x] All existing functionality preserved - [x] Code is modular and testable - [x] New tools can be added without modifying existing code - [x] Clear separation of concerns - [x] Improved type safety - [x] Better error handling and logging - [x] Zero compilation errors and diagnostic issues ## Implementation Results ### Key Achievements - **Reduced entry point**: From 1780 lines to 24 lines (98.7% reduction) - **Modular architecture**: 6 directories with clear separation of concerns - **Type safety**: Full TypeScript compliance with explicit type annotations - **Error-free build**: Zero compilation errors and diagnostic issues - **Maintainability**: Easy to add new tools without modifying existing code - **Backward compatibility**: All original functionality preserved ### Architecture Benefits - **Config**: Unified configuration with CLI and environment support - **Types**: Centralized type definitions and PocketBase extensions - **Utils**: Reusable utilities for errors, responses, and TypeScript parsing - **Tools**: Modular tool schemas and handlers for easy extension - **Server**: Clean MCP server implementation with proper dependency injection ### Technical Improvements - Proper error handling with standardized responses - Type-safe tool handlers with consistent interfaces - Modular schema definitions for better maintainability - Utility functions for common operations - Clean separation between configuration, business logic, and presentation
