Design Planning ### 2.1 Interface Enhancement Strategy **Phase 2A: MCP SDK Integration (CRITICAL)** ```typescript // Replace custom HTTP server with official MCP SDK import { McpServer, ResourceTemplate } from "@modelcontextprotocol/sdk/server/mcp.js"; import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js"; import { z } from "zod"; const server = new McpServer({ name: "euconquisto-composer", version: "0.1.1" }); // STDIO transport for Claude Desktop integration const transport = new StdioServerTransport(); ``` **Phase 2B: JSON-RPC 2.0 Protocol Compliance (CRITICAL)** ```typescript // All messages must follow exact JSON-RPC 2.0 format interface MCPRequest { jsonrpc: "2.0"; // Exact string required id: string | number; // Unique request identifier method: string; // MCP method name params?: any; // Optional parameters } interface MCPResponse { jsonrpc: "2.0"; // Exact string required id: string | number; // Echo request ID exactly result?: any; // Success result error?: { // Error object (JSON-RPC standard) code: number; message: string; data?: any; }; } ``` **Phase 2C: Educational Interface Bridge Implementation (HIGH)** ```typescript // Bridge existing interfaces to MCP primitives class EducationalContentBridge { constructor( private contentAPI: ContentAPI, private educationalAPI: EducationalAPI, private authManager: AuthenticationManager ) {} // Map ContentElementType → MCP Resources registerContentResources(server: McpServer): void { server.resource("lesson-content", new ResourceTemplate("edu://{subject}/{grade}/lesson/{lessonId}") ); } // Map EducationalAPI methods → MCP Tools registerEducationalTools(server: McpServer): void { server.tool("create-lesson", { topic: z.string(), gradeLevel: z.string(), duration: z.number() }, async (params) => this.educationalAPI.generateCourse({ topic: params.topic, gradeLevel: params.gradeLevel, estimatedDuration: params.duration })); } } ``` ### 2.2 Integration Architecture Design **MCP-Compliant Integration Architecture:** ``` ┌─────────────────────────────────────────┐ │ Claude Desktop (Host) │ │ │ │ ┌─────────────────────────────┐ │ │ │ MCP Client (Built-in) │ │ │ └─────────────────────────────┘ │ └─────────────────────────────────────────┘ ↓ STDIO Transport ↓ (stdin/stdout) ↓ JSON-RPC 2.0 ┌─────────────────────────────────────────┐ │ MCP Server Layer │ │ ┌─────────────┐ ┌─────────────────────┐ │ │ │ JSON-RPC │ │ Capability │ │ │ │ 2.0 Handler │ │ Negotiation │ │ │ │ (SDK) │ │ (Resources/Tools/ │ │ │ └─────────────┘ │ Prompts) │ │ │ └─────────────────────┘ │ └─────────────────────────────────────────┘ ┌─────────────────────────────────────────┐ │ MCP Primitives Layer │ │ ┌─────────────┐ ┌─────────────────────┐ │ │ │ Resources │ │ Tools & Prompts │ │ │ │ (Educational│ │ (Educational │ │ │ │ Content) │ │ Operations) │ │ │ └─────────────┘ └─────────────────────┘ │ └─────────────────────────────────────────┘ ┌─────────────────────────────────────────┐ │ Educational Logic Layer │ │ ┌─────────────┐ ┌─────────────────────┐ │ │ │ Existing │ │ Existing Interfaces │ │ │ │ Interfaces │ │ (Bridge Adapters) │ │ │ └─────────────┘ └─────────────────────┘ │ └─────────────────────────────────────────┘ ``` **Critical MCP Compliance Requirements:** 1. **Transport Layer**: STDIO (stdin/stdout) with newline-delimited JSON 2. **Protocol Layer**: JSON-RPC 2.0 exact compliance (jsonrpc: "2.0") 3. **SDK Integration**: Official `@modelcontextprotocol/sdk` for TypeScript 4. **Authentication**: Environment variables (not OAuth for local servers) 5. **Lifecycle Management**: Initialization → Operation → Shutdown phases **MCP Primitive Mapping Strategy:** ```typescript // Resources (Educational Content Exposure) server.resource("lesson-content", new ResourceTemplate("edu://{subject}/{grade}/lesson/{lessonId}") ); server.resource("composition-library", new ResourceTemplate("composer://compositions/{compositionId}") ); // Tools (Educational Operations) server.tool("create-lesson", { topic: z.string(), gradeLevel: z.string(), duration: z.number() }, async (params) => { /* bridge to EducationalAPI */ }); server.tool("select-widgets", { contentType: z.string(), difficulty: z.enum(["beginner", "intermediate", "advanced"]) }, async (params) => { /* bridge to ContentAPI */ }); // Prompts (Educational Templates) server.prompt("lesson-template", async (args) => ({ messages: [ { role: "user", content: "Create lesson plan for {{topic}} targeting {{grade}}" } ] })); ``` ### 2.3 Data Validation & Type Safety Requirements **Enhanced Validation Framework:** ```typescript interface ValidationFrameworkEnhanced { // Multi-level validation validateAtLayer(layer: ValidationLayer, data: any): Promise<LayeredValidationResult>; // Cross-interface validation validateComposition(composition: ContentComposition): Promise<CompositionValidationResult>; validateCourseGeneration(spec: CourseSpecification): Promise<CourseValidationResult>; // Real-time validation createValidationStream(target: ValidatableTarget): ValidationStream; // Custom validation rules registerCustomValidator(name: string, validator: CustomValidator): void; } ``` ### 2.4 Interface Versioning & Compatibility Strategy **Versioning Approach:** - **Semantic Versioning**: Follow semver for interface changes - **Backward Compatibility**: Maintain compatibility through adapter patterns - **Migration Support**: Provide migration utilities for interface updates - **Version Negotiation**: Support multiple interface versions in MCP server **Compatibility Matrix:** | Interface Version | MCP Server Version | TypeScript Version | Node.js Version | |---|---|---|---| | 0.1.x | 0.1.x | ^5.0.0 | >=18.0.0 | | 0.2.x (planned) | 0.2.x | ^5.0.0 | >=18.0.0 | ## 📋 3.
