A Critical Look at MCP
The post critically examines the Model Context Protocol (MCP), designed to standardize how applications interface with large language models (LLMs). It highlights issues such as poor documentation, unconventional design choices, and problematic implementation of HTTP transport methods. It also discusses alternatives like IBM's Agent Communication Protocol and Google's Agent2Agent protocol. The author suggests WebSockets for HTTP transport over currently proposed methods like SSE/Streamable HTTP and emphasizes the need for mature engineering practices.
