MCP Everything

AI-native conversational platform for automatically generating and hosting Model Context Protocol (MCP) servers through natural language chat.

Status (January 2025)

Integration-Ready MVP - Awaiting First Production Run

✅ What's Built (Code Complete)

• Complete LangGraph state machine with 8 intelligent nodes
• LibreChat-inspired Angular frontend with SSE streaming
• Claude Haiku 3.5 AI integration (cost-effective at $0.001/turn)
• PostgreSQL schema for conversations and checkpoints
• Full chat API with real-time updates
• Comprehensive E2E test suite (80+ Playwright tests)
• All core services implemented (GitHub analysis, tool discovery, code generation, validation)

⚠️ What Needs Validation

• Services not running - Backend and frontend need to be started
• Database not initialized - PostgreSQL setup required
• Zero MCP servers generated - Core generation pipeline untested in practice
• No end-to-end testing - Full workflow needs real-world validation

🎯 Next Steps

Phase 1: Validate Core Generator (Week 1-2)

1. Initialize PostgreSQL database
2. Start backend and frontend services
3. Generate first MCP server from any input (GitHub repo, API docs, service name, natural language)
4. Validate complete workflow end-to-end
5. Fix bugs discovered during real usage

Phase 2: Build Business Foundation (Week 3-6)

1. User authentication system (OAuth/email)
2. Stripe payment integration
3. MCP server hosting infrastructure
4. Subscription/billing system

Phase 3: Complete Marketplace (Week 7-9)

1. Marketplace backend API
2. Server storage and retrieval
3. Search functionality
4. Download/deployment features

See ROADMAP.md for complete feature alignment analysis.

Current Reality: High-quality, well-architected code generator (60% of original vision) that's never been battle-tested. Missing: revenue model, hosting infrastructure, marketplace backend, and authentication.

Quick Start

Prerequisites

• Node.js 20.19+
• PostgreSQL 13+
• Docker (for building MCP servers)

Installation

# Clone repository
git clone https://github.com/4eyedengineer/mcp-everything.git
cd mcp-everything

# Install dependencies
npm install

# Configure environment
cp .env.example .env
# Edit .env with your API keys:
# - ANTHROPIC_API_KEY (from console.anthropic.com)
# - GITHUB_TOKEN (Personal Access Token with gist permissions)

Running Locally

# Terminal 1: Backend
npm run dev:backend

# Terminal 2: Frontend
npm run dev:frontend

# Open browser to http://localhost:4200

Using the Platform

Simply chat naturally to generate MCP servers from any source:

You: "Generate an MCP server for https://github.com/expressjs/express"
AI:  [Analyzes GitHub repository, creates MCP server]

You: "Create tools for the Stripe API"
AI:  [Searches for Stripe documentation, creates MCP server]

You: "I need to process payments in my app"
AI:  [Identifies payment services, researches APIs, creates MCP server]

You: "Build tools from https://docs.stripe.com/api"
AI:  [Analyzes API documentation, creates MCP server]

The AI automatically:

• Detects your intent from natural language
• Supports multiple input types: GitHub URLs, websites, API docs, service names, natural language
• Researches and synthesizes information from multiple sources
• Asks clarifying questions when needed
• Generates complete, working MCP servers

4. clarificationOrchestrator: AI-powered gap detection & iterative clarification
5. refinementLoop: Generate-Test-Refine cycle until all tools work
6. clarifyWithUser: Multi-turn conversation support
7. provideHelp: User assistance and guidance
8. handleError: Graceful error recovery

Frontend Design

• LibreChat-Inspired: Clean, minimal aesthetic
• Collapsible Sidebar: Conversation history management
• Centered Chat: Focused, distraction-free interface
• Top Navigation: Model selector and navigation
• Responsive: Mobile-optimized design
• Custom Components: Lightweight, no heavy Material components

Backend Services

• GraphOrchestrationService: LangGraph workflow execution
• ResearchService: Input-agnostic research (GitHub/web/APIs/docs)
• EnsembleService: Parallel reasoning with 4 specialist agents
• ClarificationService: AI-powered gap detection
• RefinementService: Generate-Test-Refine loop
• McpTestingService: Docker-based MCP server validation
• GitHubAnalysisService: Repository analysis with Octokit
• McpGenerationService: MCP server code generation
• CodeExecutionService: Secure validation

Technology Stack

Backend

• NestJS + TypeScript
• LangGraph for state machine orchestration
• PostgreSQL with TypeORM
• Claude Haiku 3.5 (cost-effective AI)
• Server-Sent Events (SSE) for streaming

Frontend

• Angular 20
• Custom form controls and styling
• Responsive design patterns
