## [2.8.0] - 2025-07-08
### Added
- **NEW: SSE (Server-Sent Events) mode** - Full implementation for n8n MCP Server Trigger integration
- **NEW: SSE endpoints** - `/sse` for event streams, `/mcp/message` for async requests
- **NEW: SSE Session Manager** - Manages multiple concurrent SSE connections with lifecycle handling
- **NEW: MCP protocol over SSE** - Enables real-time event streaming and async tool execution
- **NEW: Docker Compose SSE configuration** - `docker-compose.sse.yml` for easy deployment
- **NEW: SSE test scripts** - `npm run test:sse` for verification and debugging
- **NEW: n8n workflow example** - Example workflow for MCP Server Trigger with SSE
### Features
- **Real-time communication** - SSE enables push-based updates from server to n8n
- **Long-running operations** - Better support for async and long-running tool executions
- **Multiple connections** - Support for multiple concurrent n8n workflows
- **Keep-alive pings** - Automatic connection maintenance every 30 seconds
- **Session management** - Automatic cleanup of inactive sessions (5-minute timeout)
- **Backward compatibility** - Legacy `/mcp` endpoint still available
### Documentation
- Complete SSE implementation guide at `docs/SSE_IMPLEMENTATION.md`
- Updated README with SSE mode instructions
- Added SSE testing and deployment documentation
- n8n configuration examples for MCP Server Trigger
