MCP Memory Server

# CLAUDE.md Guidelines ## Project Structure This is a memory server for MCP (Multi-Client Protocol) that uses PostgreSQL with pgvector for vector similarity search. ## Commands - `npm start`: Start server with Node.js - `npm run dev`: Start with nodemon for development (auto-reload) - `npm run prisma:migrate`: Initialize database (mentioned in README but not in package.json) ## Code Style - Use ES Module imports (type: "module") - camelCase for variables and functions - Descriptive naming with clear purpose - Structured error handling with try/catch and detailed logging - JSON-RPC response format with proper error codes ## Database - PostgreSQL with pgvector extension - Use UUID primary keys with gen_random_uuid() - Store JSON content with JSONB type - Include created_at/updated_at timestamps ## Best Practices - Use sendLogMessage() for consistent logging with levels - Document functions with clear comments - Include parameter descriptions in method definitions - Validate inputs before use - Use environment variables via dotenv for configuration
