# Interface Integration Validation Strategy **Document Version**: 1.1 **Project Version**: 0.1.0 **Last Updated**: 2025-06-08 **Revision**: MCP Compliance Integration **Status**: Phase 1 Revised - Ready for Phase 2 ## 🎯 Overview This document defines the comprehensive validation strategy for TASK-F002: Interface Integration, ensuring ≥90% test coverage, type safety, MCP compliance, and integration reliability across all enhanced interfaces with full JSON-RPC 2.0 and STDIO transport validation. ## 📋 Validation Framework Architecture ### Multi-Layer Validation Approach ``` ┌─────────────────────────────────────────┐ │ MCP Compliance Layer │ │ ┌─────────────┐ ┌─────────────────────┐ │ │ │ JSON-RPC │ │ STDIO Transport │ │ │ │ 2.0 Exact │ │ & Protocol │ │ │ │ Validation │ │ Lifecycle │ │ │ └─────────────┘ └─────────────────────┘ │ └─────────────────────────────────────────┘ ┌─────────────────────────────────────────┐ │ Type Safety Layer │ │ ┌─────────────┐ ┌─────────────────────┐ │ │ │ TypeScript │ │ Static Analysis │ │ │ │ Compilation │ │ & Linting │ │ │ └─────────────┘ └─────────────────────┘ │ └─────────────────────────────────────────┘ ┌─────────────────────────────────────────┐ │ Unit Testing Layer │ │ ┌─────────────┐ ┌─────────────────────┐ │ │ │ Interface │ │ Method Signature │ │ │ │ Compliance │ │ Validation │ │ │ └─────────────┘ └─────────────────────┘ │ └─────────────────────────────────────────┘ ┌─────────────────────────────────────────┐ │ Integration Testing Layer │ │ ┌─────────────┐ ┌─────────────────────┐ │ │ │ Cross- │ │ Claude Desktop │ │ │ │ Interface │ │ Integration │ │ │ └─────────────┘ └─────────────────────┘ │ └─────────────────────────────────────────┘ ┌─────────────────────────────────────────┐ │ Performance Testing Layer │ │ ┌─────────────┐ ┌─────────────────────┐ │ │ │ Response │ │ Throughput & │ │ │ │ Time Tests │ │ Load Testing │ │ │ └─────────────┘ └─────────────────────┘ │ └─────────────────────────────────────────┘ ``` ## 📋 MCP Compliance Validation ### JSON-RPC 2.0 Protocol Testing **Message Format Validation:** ```typescript describe('JSON-RPC 2.0 Compliance', () => { it('should use exact "2.0" jsonrpc version', () => { const message = createMCPRequest('list_resources'); expect(message.jsonrpc).toBe('2.0'); }); it('should include unique request IDs', () => { const req1 = createMCPRequest('list_tools'); const req2 = createMCPRequest('list_resources'); expect(req1.id).toBeDefined(); expect(req2.id).toBeDefined(); expect(req1.id).not.toBe(req2.id); }); it('should handle proper error codes', () => { const errorResponse = { jsonrpc: '2.0', id: 'test-123', error: { code: -32602, // Invalid params message: 'Invalid parameters', data: { /* additional error data */ } } }; expect(validateJSONRPCError(errorResponse)).toBe(true); }); }); ``` ### STDIO Transport Validation **Communication Protocol Testing:** ```typescript describe('STDIO Transport Integration', () => { it('should initialize via stdin/stdout', async () => { const server = new McpServer({ name: 'test-server', version: '1.0.0' }); const transport = new StdioServerTransport(); await server.connect(transport); expect(server.isConnected()).toBe(true); }); it('should handle newline-delimited JSON', () => { const message1 = '{"jsonrpc":"2.0","method":"list_resources","id":"1"}'; const message2 = '{"jsonrpc":"2.0","method":"list_tools","id":"2"}'; const combined = message1 + '\n' + message2 + '\n'; const parsed = parseStdioMessages(combined); expect(parsed).toHaveLength(2); expect(parsed[0].method).toBe('list_resources'); expect(parsed[1].method).toBe('list_tools'); }); it('should gracefully handle connection termination', async () => { const server = createTestMCPServer(); await server.close(); expect(server.isConnected()).toBe(false); }); }); ``` ### MCP Lifecycle Testing **Initialization Handshake Validation:** ```typescript describe('MCP Lifecycle Management', () => { it('should complete proper initialization sequence', async () => { const initRequest = { jsonrpc: '2.0', id: 'init-1', method: 'initialize', params: { protocolVersion: '2025-03-26', capabilities: {}, clientInfo: { name: 'test-client', version: '1.0.0' } } }; const response = await handleInitialize(initRequest); expect(response.result.protocolVersion).toBe('2025-03-26'); expect(response.result.capabilities).toBeDefined(); expect(response.result.serverInfo.name).toBe('euconquisto-composer'); }); it('should declare all required capabilities', () => { const capabilities = getServerCapabilities(); expect(capabilities.resources).toBeDefined(); expect(capabilities.tools).toBeDefined(); expect(capabilities.prompts).toBeDefined(); }); it('should handle initialized notification', () => { const notification = { jsonrpc: '2.0', method: 'initialized' }; expect(() => handleInitialized(notification)).not.toThrow(); }); }); ``` ## 📋 Resource/Tool/Prompt Validation ### Resource Integration Testing **Educational Content Resource Validation:** ```typescript describe('Educational Resource Integration', () => { it('should expose content elements as MCP resources', async () => { const resources = await listResources(); const contentResource = resources.find(r => r.uri.startsWith('content://')); expect(contentResource).toBeDefined(); expect(contentResource.name).toContain('Content Elements'); }); it('should support URI template navigation', async () => { const uri = 'content://text/element-123'; const resource = await readResource(uri); expect(resource.contents).toBeDefined(); expect(resource.mimeType).toBe('application/json'); }); it('should validate resource permissions', async () => { const restrictedUri = 'content://admin/sensitive-data'; await expect(readResource(restrictedUri)).rejects.toThrow('Access denied'); }); }); ``` ### Tool Execution Validation **Educational API Tool Testing:** ```typescript describe('Educational Tool Integration', () => { it('should map ContentAPI methods to MCP tools', async () => { const tools = await listTools(); const createElementTool = tools.find(t => t.name === 'create-element'); expect(createElementTool).toBeDefined(); expect(createElementTool.inputSchema.properties.elementType).toBeDefined(); }); it('should validate tool parameter schemas', async () => { const toolCall = { name: 'create-element', arguments: { elementType: 'text', content: { text: 'Hello world' }, metadata: { subject: 'english' } } }; const result = await callTool(toolCall.name, toolCall.arguments); expect(result.content).toBeDefined(); expect(result.isError).toBe(false); }); it('should require user consent for tool execution', async () => { const sensitiveToolCall = { name: 'delete-course', arguments: { courseId: 'course-123' } }; // Should prompt for user consent await expect(callTool(sensitiveToolCall.name, sensitiveToolCall.arguments)) .rejects.toThrow('User consent required'); }); }); ``` ### Prompt Template Validation **Educational Prompt Testing:** ```typescript describe('Educational Prompt Integration', () => { it('should provide lesson plan templates', async () => { const prompts = await listPrompts(); const lessonTemplate = prompts.find(p => p.name === 'lesson-plan-template'); expect(lessonTemplate).toBeDefined(); expect(lessonTemplate.arguments).toContain('topic'); expect(lessonTemplate.arguments).toContain('gradeLevel'); }); it('should render prompt templates with arguments', async () => { const promptResult = await getPrompt('lesson-plan-template', { topic: 'Photosynthesis', gradeLevel: '5th Grade', duration: 45 }); expect(promptResult.messages).toHaveLength(1); expect(promptResult.messages[0].content).toContain('Photosynthesis'); expect(promptResult.messages[0].content).toContain('5th Grade'); }); }); ``` ## 📋 Success Metrics ### Phase 1 Validation Success Criteria - ✅ **Type Safety**: 100% TypeScript strict mode compliance - ✅ **Interface Coverage**: All 4 interface files mapped and documented - ✅ **MCP Compliance Planning**: All MCP primitive mappings defined - ✅ **Integration Planning**: Cross-interface relationships identified for MCP integration - ✅ **Test Strategy**: Comprehensive testing approach defined with MCP validation - ✅ **Performance Targets**: Benchmarks and thresholds established for STDIO transport ### Phase 2 Implementation Success Criteria - 🎯 **MCP Protocol Compliance**: 100% JSON-RPC 2.0 and STDIO transport compliance - 🎯 **Test Coverage**: ≥90% code coverage across all enhanced interfaces and MCP integration - 🎯 **Performance**: All response time benchmarks met for STDIO communication - 🎯 **Integration**: All cross-interface workflows validated with MCP primitives - 🎯 **Claude Desktop Compatibility**: Full integration testing with actual Claude Desktop ### Overall Task Success Criteria - 🎯 **MCP Server Compliance**: Complete STDIO + JSON-RPC 2.0 implementation with official SDK - 🎯 **Interface Enhancement**: All planned enhancements implemented with MCP bridge adapters - 🎯 **Documentation**: Complete interface documentation with MCP primitive mapping examples - 🎯 **Quality Assurance**: All quality gates passed including MCP compliance validation - 🎯 **Production Readiness**: System validated for Claude Desktop integration and deployment --- ## 📜 Document Information **Document Version**: 1.1 **Project Version**: 0.1.0 **Task**: TASK-F002 Interface Integration **Phase**: 1 - Planning & Design (MCP Compliance Revision) **Revision**: MCP Compliance Integration **Status**: Phase 1 Revised - Ready for Phase 2 **Next Phase**: MCP-Compliant Implementation (Phase 2) **Created**: 2025-06-08 **Last Updated**: 2025-06-08 **Review Required**: Yes (MCP compliance verification before Phase 2) --- *EuConquisto Composer MCP Server PoC - Interface Integration Validation Strategy v1.1* *MCP Compliance Integration Testing Framework*
