MCP Brain Service

Perfect! I've created a comprehensive **brain-implement.md** document that gives you everything needed to build the MCP Brain Service in parallel with your Auto-Movie app. ## Key Features of This Implementation Guide: ### **🏗 Complete Step-by-Step Build Process** 1. **Project Structure** - Organized Python service with proper module separation 2. **Configuration** - Environment-based settings with validation 3. **Core Services** - Jina v4 + Neo4j integration with caching 4. **MCP Protocol** - Full WebSocket server with tool registry 5. **Testing Framework** - Mock data and validation scripts ### **📋 Ready-to-Copy Code** - **Configuration management** with Pydantic settings - **Jina v4 service** with embedding generation and similarity search - **Neo4j service** with vector indexes and graph operations - **MCP tools** for character creation and semantic search - **WebSocket server** with full MCP protocol support ### **🎯 Clear Success Milestones** ```bash ✅ Milestone 1: Basic setup and dependencies ✅ Milestone 2: Core services working (Jina + Neo4j) ✅ Milestone 3: MCP server accepting connections/p ✅ Milestone 4: Character operations with embeddings ✅ Milestone 5: Production deployment at brain.ft.tc ``` ### **🧪 Built-in Testing** - **Connection testing** with WebSocket clients - **Character creation** and similarity search validation - **Mock data** for independent development - **Integration testing** scripts ready ## Perfect for Parallel Development: ### **While Building Auto-Movie App:** - **Different tech stack** (Python vs Next.js) - **Independent testing** with mock data - **No integration dependencies** during development - **Clear API contract** defined upfront ### **Development Flow:** ```bash # Terminal 1: Auto-Movie development cd auto-movie npm run dev # Terminal 2: Brain service development cd mcp-brain-service python run_dev.py # Terminal 3: Test integration python test_basic.py ``` ## What You Get After Implementation: ### **Working Knowledge Graph Service** - Create characters with personality/appearance embeddings - Find similar characters using semantic search - Project-scoped data isolation - WebSocket MCP protocol for agent integration ### **Ready for Auto-Movie Integration** ```typescript // Auto-Movie can immediately connect and use: const brainClient = new MCPClient('wss://brain.ft.tc') const similar = await brainClient.findSimilarCharacters(query) ``` The implementation is designed to be **production-ready** from the start, with proper error handling, logging, and deployment scripts. **Ready to start building both services in parallel?** This guide will get your Brain service online at brain.ft.tc while you develop the Auto-Movie interface!
