MCP App Platform

What it does

MCP App Platform is a multi-tenant MCP server that hosts several independent MCP Apps under one deployment. Each app gets its own route (/{app-id}/mcp), its own React UI rendered via the MCP Apps extension, and shared infrastructure for authentication, routing, and session management. Currently ships three apps: Recipe Remix (cooking assistant), PDF Insight (PDF reader with notes), and Allocation Remix (portfolio allocation tool).

Key features

• Multi-app routing — each app lives in its own folder with server.ts (tools/resources) and mcp-app.tsx (React UI), registered via a central app registry
• Streamable HTTP transport — SSE-based connections for real-time streaming
• PDF Insight — reads PDFs, highlights passages, takes notes with SQLite persistence, full Vitest test suite
• Recipe Remix — interactive cooking assistant with ingredient substitutions and recipe visualisation
• Railway deployment — auto-builds from main, live at https://mcp-production-3a5e.up.railway.app
• Optional API key auth — set API_KEY env var to restrict access
