# Phase 2: MCP Server Core Development ## Overview This phase focuses on developing the core MCP server, which will serve as the central communication hub between AI agents and the target applications (Blender and Unreal Engine). ## Tasks ### 1. Server Framework Setup - [x] Implement FastAPI application structure - [x] Set up SSE (Server-Sent Events) endpoint at `/stream` - [x] Implement basic request/response handling ### 2. Connection Management - [x] Create abstract Connection base class for application interfaces - [x] Implement BlenderConnection class (adapting from blender-mcp) - [x] Create UnrealConnection class structure - [x] Implement connection management and error handling ### 3. API Design and Implementation - [x] Define common API interface for both applications - [x] Implement API routing mechanisms - [x] Create error handling and response formatting - [x] Add request validation ### 4. Langchain Integration - [x] Set up basic Langchain components - [x] Implement memory/state management - [x] Configure document processing capabilities - [x] Create prompt templates for AI agent interactions ### 5. Tool Function Implementation - [x] Define Blender tool functions (adapting from blender-mcp) - [x] Create Unreal Engine tool function scaffolding - [x] Implement common utilities and helper functions - [x] Add input validation for all tool functions ### 6. Testing Framework - [x] Create unit tests for server components - [x] Implement mock connections for testing - [x] Add integration test structure - [x] Create test utilities for simulating requests ## Testing Procedures - Test SSE connection stability and message handling - Verify API endpoints function correctly - Test Langchain state management with sample inputs - Validate error handling across different scenarios - Test connection management with mock clients ## Deliverables - Functional MCP server with SSE support - Connection management system for both applications - API routing and request handling - Basic Langchain integration - Tool function definitions with validation - Test suite for core functionality
