Production-ready MCP IMAP server for hosted N8N workflows. Changes: - SSE transport using create_sse_app() for N8N compatibility - API key authentication middleware for multi-tenant access - Systemd service file for auto-restart on Hetzner - Nginx reverse proxy config with TLS and rate limiting - Complete deployment guide (DEPLOY.md) - Removed REST API bridge (api_server.py) - N8N uses MCP protocol Deployment: - SSE endpoint: https://imap.maxtheweb.ai/mcp/sse - Messages endpoint: https://imap.maxtheweb.ai/mcp/messages - Authentication: Bearer token in Authorization header Stack: FastMCP 2.13 + uvicorn + nginx + systemd
