MCP Login Server

# Refactoring Summary ## Changes Made ### 1. Created `src/tools.ts` - **Purpose**: Centralized tool definitions and registration - **Benefits**: - Separates tool logic from server setup - Makes adding new tools easier - Improves code organization and maintainability ### 2. Refactored `src/index.ts` - **Before**: 220 lines with server setup + all tool definitions - **After**: 51 lines focused only on server setup and startup - **Changes**: - Removed all tool definitions - Added import for tool registration functions - Simplified main function - Used `getAvailableTools()` for logging ### 3. New Architecture #### `src/tools.ts` exports: - `LOGIN_CREDENTIALS`: Configuration constants - `registerPerformLoginTool()`: Individual tool registration - `registerGetLoginCredentialsTool()`: Individual tool registration - `registerTestConnectionTool()`: Individual tool registration - `registerAllTools()`: Registers all tools at once - `getAvailableTools()`: Returns array of tool names #### `src/index.ts` responsibilities: - Server configuration and instantiation - Tool registration (via `registerAllTools()`) - Transport setup and connection - Process management and graceful shutdown - Startup logging ## Benefits 1. **Modularity**: Tools are self-contained and can be developed independently 2. **Extensibility**: Adding new tools requires minimal changes to existing code 3. **Maintainability**: Clear separation of concerns makes code easier to understand 4. **Testing**: Individual tools can be tested in isolation 5. **Reusability**: Tool definitions can be easily shared between projects ## Adding New Tools To add a new tool, developers only need to: 1. Create a new `registerYourTool()` function in `tools.ts` 2. Add it to the `registerAllTools()` function 3. Add the tool name to `getAvailableTools()` See `ADDING_TOOLS.md` for detailed instructions. ## Verification - ✅ Server starts successfully - ✅ All three tools are registered correctly - ✅ MCP protocol communication works - ✅ No TypeScript compilation errors - ✅ Tools can be listed via MCP protocol The refactoring is complete and the server maintains full compatibility with the original implementation while being much more extensible.
