Specif-ai MCP Server

# Architecture Guide ## System Overview The Specif-ai MCP Server implements the Model Context Protocol (MCP) over stdio, providing a standardized interface for managing requirement documents. The system follows a service-oriented architecture with clear separation of concerns. ```mermaid graph TD A[MCP Client] -->|stdio| B[Server Service] B --> C[Document Service] C --> D[File Service] B --> E[Logger] C --> F[Solution Data] ``` ## Core Components ### 1. Server Service (`server.service.ts`) - Main entry point for MCP protocol implementation - Handles tool registration and execution - Manages request/response flow - Implements stdio transport layer - Key responsibilities: - Tool registration - Request validation - Response formatting - Error handling - Session management ### 2. Document Service (`document.service.ts`) - Manages document operations - Handles document loading and parsing - Provides document search and retrieval - Key responsibilities: - Solution loading - Document type management - Document search - Data validation ### 3. File Service (`file.service.ts`) - Handles file system operations - Manages file reading and writing - Implements file system abstractions - Key responsibilities: - File reading - Directory scanning - Path resolution - Error handling ## Data Flow 1. **Request Processing** ```mermaid sequenceDiagram Client->>Server: Tool Request Server->>Validator: Validate Input Validator-->>Server: Validation Result Server->>DocumentService: Process Request DocumentService->>FileService: Read Data FileService-->>DocumentService: File Data DocumentService-->>Server: Document Data Server-->>Client: Formatted Response ``` 2. **Error Handling** ```mermaid sequenceDiagram participant C as Client participant S as Server participant E as Error Handler participant L as Logger C->>S: Invalid Request S->>E: Validate E->>L: Log Error E-->>S: Error Details S-->>C: Error Response ```
