+# MCPHub Coding Instructions
+
+## Project Overview
+
+MCPHub is a TypeScript/Node.js MCP server management hub that provides unified access through HTTP endpoints.
+
+**Core Components:**
+
+- **Backend**: Express.js + TypeScript + ESM (`src/server.ts`)
+- **Frontend**: React/Vite + Tailwind CSS (`frontend/`)
+- **MCP Integration**: Connects multiple MCP servers (`src/services/mcpService.ts`)
+
+## Development Environment
+
+```bash
+pnpm install
+pnpm dev           # Start both backend and frontend
+pnpm backend:dev   # Backend only
+pnpm frontend:dev  # Frontend only
+```
+
+## Project Conventions
+
+### File Structure
+
+- `src/services/` - Core business logic
+- `src/controllers/` - HTTP request handlers
+- `src/types/index.ts` - TypeScript type definitions
+- `src/config/index.ts` - Configuration management
+
+### Key Notes
+
+- Use ESM modules: Import with `.js` extensions, not `.ts`
+- Configuration file: `mcp_settings.json`
+- Endpoint formats: `/mcp/{group|server}` and `/mcp/$smart`
+- All code comments must be written in English
+- Frontend uses i18n with resource files in `locales/` folder
+- Server-side code should use appropriate abstraction layers for extensibility and replaceability
+
+## Development Process
+
+- For complex features, implement step by step and wait for confirmation before proceeding to the next step
+- After implementing features, no separate summary documentation is needed - update README.md and README.zh.md as appropriate
+
+### Development Entry Points
+
+- **MCP Servers**: Modify `src/services/mcpService.ts`
+- **API Endpoints**: Add routes in `src/routes/`, controllers in `src/controllers/`
+- **Frontend Features**: Start from `frontend/src/pages/`
+- **Testing**: Follow existing patterns in `tests/`
