This critical look focuses just on the protocol. The fun starts with the actual MCP server implementations... Seems that providing an MCP server is the to be or not to be for all sorts of vendors. All REST APIs get wrapped into an MCP to make products LLM-compatible and tick checkmarks on newly extended checklists. Many pass REST responses directly to LLMs that quickly leads to token burn. Wish providers took a closer look on the actual engineering practices for the servers. Has someone seen a good implementation of an MCP server with a comprehensive test suite?
