模型上下文协议更新为无状态设计,对服务器提出新要求

模型上下文协议 (MCP) 已更新至 2026-07-28 版本,为服务器作者带来了重大变化。该协议现在是无状态的,无需进行初始化握手,并要求在每个请求的 `_meta` 字段中包含协议版本和客户端功能。服务器现在必须实现 `server/discover` 端点,并在所有结果中包含 `resultType` 字段。错误代码也已重新编号,`UnsupportedProtocolVersionError` 从 -32004 移至 -32022。此外,现在某些结果需要 `ttlMs` 和 `cacheScope` 等缓存提示。 AI

影响 要求服务器作者更新实现,以符合新的无状态协议和错误处理。
