MCP HTTP Server

mcp-http-server is a high-performance HTTP server designed specifically for the Model Context Protocol (MCP) ecosystem, providing robust transport for both standard HTTP POST and Server-Sent Events (SSE). It offers flexible routing configurations, allows access to HTTP headers within the MCP server context, and supports custom Express-style middleware for extending server logic. The package currently maintains a stable version 1.2.4, suggesting a mature and consistent API for its core functionality. While originating from the broader UI-TARS-desktop project on GitHub, its specific release cadence appears independent of the more rapid beta iterations seen in related `@agent-tars` components. Key differentiators include its dual support for stateful and stateless modes for streamable HTTP, making it suitable for diverse real-time communication needs where MCP interactions are central.
