-# MCPHub Coding Instructions
-
-**ALWAYS follow these instructions first and only fallback to additional search and context gathering if the information here is incomplete or found to be in error.**
-
-## Project Overview
-
-MCPHub is a TypeScript/Node.js MCP (Model Context Protocol) server management hub that provides unified access through HTTP endpoints. It serves as a centralized dashboard for managing multiple MCP servers with real-time monitoring, authentication, and flexible routing.
-
-**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`)
-- **Authentication**: JWT-based with bcrypt password hashing
-- **Configuration**: JSON-based MCP server definitions (`mcp_settings.json`)
-- **Documentation**: API docs and usage instructions(`docs/`)
-
-## Working Effectively
-
-### Bootstrap and Setup (CRITICAL - Follow Exact Steps)
-
-```bash
-# Install pnpm if not available
-npm install -g pnpm
-
-# Install dependencies - takes ~30 seconds
-pnpm install
-
-# Setup environment (optional)
-cp .env.example .env
-
-# Build and test to verify setup
-pnpm lint                    # ~3 seconds - NEVER CANCEL
-pnpm backend:build          # ~5 seconds - NEVER CANCEL
-pnpm test:ci                # ~16 seconds - NEVER CANCEL. Set timeout to 60+ seconds
-pnpm frontend:build         # ~5 seconds - NEVER CANCEL
-pnpm build                  # ~10 seconds total - NEVER CANCEL. Set timeout to 60+ seconds
-```
-
-**CRITICAL TIMING**: These commands are fast but NEVER CANCEL them. Always wait for completion.
-
-### Development Environment
-
-```bash
-# Start both backend and frontend (recommended for most development)
-pnpm dev                    # Backend on :3001, Frontend on :5173
-
-# OR start separately (required on Windows, optional on Linux/macOS)
-# Terminal 1: Backend only
-pnpm backend:dev            # Runs on port 3000 (or PORT env var)
-
-# Terminal 2: Frontend only
-pnpm frontend:dev           # Runs on port 5173, proxies API to backend
-```
-
-**NEVER CANCEL**: Development servers may take 10-15 seconds to fully initialize all MCP servers.
-
-### Build Commands (Production)
-
-```bash
-# Full production build - takes ~10 seconds total
-pnpm build                  # NEVER CANCEL - Set timeout to 60+ seconds
-
-# Individual builds
-pnpm backend:build          # TypeScript compilation - ~5 seconds
-pnpm frontend:build         # Vite build - ~5 seconds
-
-# Start production server
-pnpm start                  # Requires dist/ and frontend/dist/ to exist
-```
-
-### Testing and Validation
-
-```bash
-# Run all tests - takes ~16 seconds with 73 tests
-pnpm test:ci                # NEVER CANCEL - Set timeout to 60+ seconds
-
-# Development testing
-pnpm test                   # Interactive mode
-pnpm test:watch             # Watch mode for development
-pnpm test:coverage          # With coverage report
-
-# Code quality
-pnpm lint                   # ESLint - ~3 seconds
-pnpm format                 # Prettier formatting - ~3 seconds
-```
-
-**CRITICAL**: All tests MUST pass before committing. Do not modify tests to make them pass unless specifically required for your changes.
-
-## Manual Validation Requirements
-
-**ALWAYS perform these validation steps after making changes:**
-
-### 1. Basic Application Functionality
-
-```bash
-# Start the application
-pnpm dev
-
-# Verify backend responds (in another terminal)
-curl http://localhost:3000/api/health
-# Expected: Should return health status
-
-# Verify frontend serves
-curl -I http://localhost:3000/
-# Expected: HTTP 200 OK with HTML content
-```
-
-### 2. MCP Server Integration Test
-
-```bash
-# Check MCP servers are loading (look for log messages)
-# Expected log output should include:
-# - "Successfully connected client for server: [name]"
-# - "Successfully listed [N] tools for server: [name]"
-# - Some servers may fail due to missing API keys (normal in dev)
-```
-
-### 3. Build Verification
-
-```bash
-# Verify production build works
-pnpm build
-node scripts/verify-dist.js
-# Expected: "✅ Verification passed! Frontend and backend dist files are present."
-```
-
-**NEVER skip these validation steps**. If any fail, debug and fix before proceeding.

-## Project Structure and Key Files
-
-### Critical Backend Files
-
-- `src/index.ts` - Application entry point
-- `src/server.ts` - Express server setup and middleware
-- `src/services/mcpService.ts` - **Core MCP server management logic**
-- `src/config/index.ts` - Configuration management

-
-### DAO Layer (Dual Data Source)
-
-MCPHub supports **JSON file** (default) and **PostgreSQL** storage:
-
-- Set `USE_DB=true` + `DB_URL=postgresql://...` to use database
-- When modifying data structures, update: `src/types/`, `src/dao/`, `src/db/entities/`, `src/db/repositories/`, `src/utils/migration.ts`
-- See `AGENTS.md` for detailed DAO modification checklist
-
-### Critical Frontend Files
-
-- `frontend/src/` - React application source
-- `frontend/src/pages/` - Page components (development entry point)
-- `frontend/src/components/` - Reusable UI components
-- `frontend/src/utils/fetchInterceptor.js` - Backend API interaction
-
-### Configuration Files
-
-- `mcp_settings.json` - **MCP server definitions and user accounts**
-- `package.json` - Dependencies and scripts
-- `tsconfig.json` - TypeScript configuration
-- `jest.config.cjs` - Test configuration
-- `.eslintrc.json` - Linting rules
-
-### Docker and Deployment
-
-- `Dockerfile` - Multi-stage build with Python base + Node.js
-- `entrypoint.sh` - Docker startup script

-- **ESM modules**: Always use `.js` extensions in imports, not `.ts`
-- **English only**: All code comments must be written in English
-- **TypeScript strict**: Follow strict type checking rules
-- **Import style**: `import { something } from './file.js'` (note .js extension)
-
-### Key Configuration Notes
-
-- **MCP servers**: Defined in `mcp_settings.json` with command/args
-- **Endpoints**: `/mcp/{group|server}` and `/mcp/$smart` for routing
-- **i18n**: Frontend uses react-i18next with files in `locales/` folder
-- **Authentication**: JWT tokens with bcrypt password hashing
-- **Default credentials**: admin/admin123 (configured in mcp_settings.json)
-
-### Development Entry Points
-
-- **Add MCP server**: Modify `mcp_settings.json` and restart
-- **New API endpoint**: Add route in `src/routes/`, controller in `src/controllers/`
-- **Frontend feature**: Start from `frontend/src/pages/` or `frontend/src/components/`
-- **Add tests**: Follow patterns in `tests/` directory
-
-### Common Development Tasks
-
-#### Adding a new MCP server:
-
-1. Add server definition to `mcp_settings.json`
-2. Restart backend to load new server
-3. Check logs for successful connection
-4. Test via dashboard or API endpoints
-
-#### API development:
-
-1. Define route in `src/routes/`
-2. Implement controller in `src/controllers/`
-3. Add types in `src/types/index.ts` if needed
-4. Write tests in `tests/controllers/`
-
-#### Frontend development:
-
-1. Create/modify components in `frontend/src/components/`
-2. Add pages in `frontend/src/pages/`
-3. Update routing if needed
-4. Test in development mode with `pnpm frontend:dev`
-
-#### Documentation:
-
-1. Update or add docs in `docs/` folder
-2. Ensure README.md reflects any major changes
-
-## Validation and CI Requirements
-
-### Before Committing - ALWAYS Run:
-
-```bash
-pnpm lint                   # Must pass - ~3 seconds
-pnpm backend:build          # Must compile - ~5 seconds
-pnpm test:ci                # All tests must pass - ~16 seconds
-pnpm build                  # Full build must work - ~10 seconds
-```
-
-**CRITICAL**: CI will fail if any of these commands fail. Fix issues locally first.
-
-### CI Pipeline (.github/workflows/ci.yml)
-
-- Runs on Node.js 20.x
-- Tests: linting, type checking, unit tests with coverage
-- **NEVER CANCEL**: CI builds may take 2-3 minutes total
-
-## Troubleshooting
-
-### Common Issues
-
-- **"uvx command not found"**: Some MCP servers require `uvx` (Python package manager) - this is expected in development
-- **Port already in use**: Change PORT environment variable or kill existing processes
-- **Frontend not loading**: Ensure frontend was built with `pnpm frontend:build`
-- **MCP server connection failed**: Check server command/args in `mcp_settings.json`
-
-### Build Failures
-
-- **TypeScript errors**: Run `pnpm backend:build` to see compilation errors
-- **Test failures**: Run `pnpm test:verbose` for detailed test output
-- **Lint errors**: Run `pnpm lint` and fix reported issues
-
-### Development Issues
-
-- **Backend not starting**: Check for port conflicts, verify `mcp_settings.json` syntax
-- **Frontend proxy errors**: Ensure backend is running before starting frontend
-- **Hot reload not working**: Restart development server
-
-## Performance Notes
-
-- **Install time**: pnpm install takes ~30 seconds
-- **Build time**: Full build takes ~10 seconds
-- **Test time**: Complete test suite takes ~16 seconds
-- **Startup time**: Backend initialization takes 10-15 seconds (MCP server connections)
-
-**Remember**: NEVER CANCEL any build or test commands. Always wait for completion even if they seem slow.

 ## Project Structure & Module Organization
 
-- Backend services live in `src`, grouped by responsibility (`controllers/`, `services/`, `dao/`, `routes/`, `utils/`), with `server.ts` orchestrating HTTP bootstrap.
-- `frontend/src` contains the Vite + React dashboard; `frontend/public` hosts static assets and translations sit in `locales/`.
-- Jest-aware test code is split between colocated specs (`src/**/*.{test,spec}.ts`) and higher-level suites in `tests/`; use `tests/utils/` helpers when exercising the CLI or SSE flows.
-- Build artifacts and bundles are generated into `dist/`, `frontend/dist/`, and `coverage/`; never edit these manually.

 ## Build, Test, and Development Commands
 
-- `pnpm dev` runs backend (`tsx watch src/index.ts`) and frontend (`vite`) together for local iteration.
-- `pnpm backend:dev`, `pnpm frontend:dev`, and `pnpm frontend:preview` target each surface independently; prefer them when debugging one stack.
-- `pnpm build` executes `pnpm backend:build` (TypeScript to `dist/`) and `pnpm frontend:build`; run before release or publishing.
-- `pnpm test`, `pnpm test:watch`, and `pnpm test:coverage` drive Jest; `pnpm lint` and `pnpm format` enforce style via ESLint and Prettier.
+### Development Environment
+
+```bash
+# Start both backend and frontend (recommended for most development)
+pnpm dev                    # Backend on :3001, Frontend on :5173
+
+# OR start separately (required on Windows, optional on Linux/macOS)

+
+# Terminal 2: Frontend only
+pnpm frontend:dev           # Runs on port 5173, proxies API to backend
+
+# Frontend preview (production build)
+pnpm frontend:preview       # Preview production build
+```
+
+**NEVER CANCEL**: Development servers may take 10-15 seconds to fully initialize all MCP servers.
+
+### Production Build
+
+```bash
+# Full production build - takes ~10 seconds total
+pnpm build                  # NEVER CANCEL - Set timeout to 60+ seconds
+
+# Individual builds
+pnpm backend:build          # TypeScript compilation to dist/ - ~5 seconds
+pnpm frontend:build         # Vite build to frontend/dist/ - ~5 seconds
+
+# Start production server
+pnpm start                  # Requires dist/ and frontend/dist/ to exist
+```
+
+Run `pnpm build` before release or publishing.
+
+### Testing and Validation
+
+```bash
+# Run all tests - takes ~16 seconds with 73 tests
+pnpm test:ci                # NEVER CANCEL - Set timeout to 60+ seconds
+
+# Development testing
+pnpm test                   # Interactive mode
+pnpm test:watch             # Watch mode for development
+pnpm test:coverage          # With coverage report

 ## Coding Style & Naming Conventions
 
-- TypeScript everywhere; default to 2-space indentation and single quotes, letting Prettier settle formatting. ESLint configuration assumes ES modules.
-- Name services and data access layers with suffixes (`UserService`, `AuthDao`), React components and files in `PascalCase`, and utility modules in `camelCase`.
-- Keep DTOs and shared types in `src/types` to avoid duplication; re-export through index files only when it clarifies imports.

 ## Commit & Pull Request Guidelines
 
 - Follow the existing Conventional Commit pattern (`feat:`, `fix:`, `chore:`, etc.) with imperative, present-tense summaries and optional multi-line context.
 - Each PR should describe the behavior change, list testing performed, and link issues; include before/after screenshots or GIFs for frontend tweaks.
 - Re-run `pnpm build` and `pnpm test` before requesting review, and ensure generated artifacts stay out of the diff.

 - Optional fields need `nullable: true` in entity
 - Complex objects need `simple-json` column type

+## Auto-Evolution Guidelines for AI Agents
+
+**This section provides guidelines for AI agents to automatically maintain and improve this document.**
+
+### When to Update AGENTS.md
+
+AI agents MUST update this document in the following situations:
+
+#### 1. Code-Documentation Mismatch Detected
+
+When executing tasks, if you discover that:
+
+- The actual code structure differs from descriptions in this document
+- File paths, imports, or module organization has changed
+- New critical files or directories exist that aren't documented
+- Documented files or patterns no longer exist
+
+**Action**: Immediately update the relevant section to reflect the current codebase state.
+
+**Example scenarios**:
+
+- A controller is now in `src/api/controllers/` instead of `src/controllers/`
+- New middleware files exist that should be documented
+- The DAO implementation has been refactored with a different structure
+- Build output directories have changed
+
+#### 2. User Preferences and Requirements
+
+During conversation, if the user expresses:
+
+- **Coding preferences**: Indentation style, naming conventions, code organization patterns
+- **Workflow requirements**: Required validation steps, commit procedures, testing expectations
+- **Tool preferences**: Preferred libraries, frameworks, or development tools
+- **Quality standards**: Code review criteria, documentation requirements, error handling patterns
+- **Development principles**: Architecture decisions, design patterns, best practices
+
+**Action**: Add or update the relevant section to capture these preferences for future reference.
+
+**Example scenarios**:
+
+- User prefers async/await over promises → Update coding style section
+- User requires specific test coverage thresholds → Update testing guidelines
+- User has strong opinions about error handling → Add to development process section
+- User establishes new deployment procedures → Update deployment section
+
+### How to Update AGENTS.md
+
+1. **Identify the Section**: Determine which section needs updating based on the type of change
+2. **Make Precise Changes**: Update only the relevant content, maintaining the document structure
+3. **Preserve Format**: Keep the existing markdown formatting and organization
+4. **Add Context**: If adding new content, ensure it fits logically within existing sections
+5. **Verify Accuracy**: After updating, ensure the new information is accurate and complete
+
+### Update Principles
+
+- **Accuracy First**: Documentation must reflect the actual current state
+- **Clarity**: Use clear, concise language; avoid ambiguity
+- **Completeness**: Include sufficient detail for agents to work effectively
+- **Consistency**: Maintain consistent terminology and formatting throughout
+- **Actionability**: Focus on concrete, actionable guidance rather than vague descriptions
+
+### Self-Correction Process
+
+Before completing any task:
+
+1. Review relevant sections of AGENTS.md
+2. During execution, note any discrepancies between documentation and reality
+3. Update AGENTS.md to correct discrepancies
+4. Verify the update doesn't conflict with other sections
+5. Proceed with the original task using the updated information
+
+### Meta-Update Rule
+
+If this auto-evolution section itself needs improvement based on experience:
+
+- Update it to better serve future agents
+- Add new scenarios or principles as they emerge
+- Refine the update process based on what works well
+
+**Remember**: This document is a living guide. Keeping it accurate and current is as important as following it.
