Summary (Chinese)
MCP 2.0 (2026-07-28 规范) 将协议从有状态改为无状态，从两次 HTTP 请求变为单次调用，服务端不再需要维护 session。复杂度断崖式下降，同时发布了 mcp-explorer、datasette-mcp、llm-mcp-client 三个实现。作者认为 MCP 比裸 shell+curl 的通用 agent 更容易审计和控制，是构建敏感 LLM 应用的更安全路径。
Summary (English)
MCP 2.0 (2026-07-28 spec) changes the protocol from stateful to stateless, reducing from two HTTP requests to a single call. Server-side session management is eliminated. Author released three implementations (mcp-explorer, datasette-mcp, llm-mcp-client). Argues MCP tools are easier to audit and control than general-purpose agents with shell access.
