+MCP 和 Hook 从同一份用户配置读取地址。Hook 在下一次调用时读取修改；更改地址或 MCP 超时后，
+请重新连接 MCP 或重启宿主，确保现有 MCP 进程也使用新配置。无需修改插件源码、安装缓存或重装插件。
+使用自定义 MCP 路径时，例如 `https://memory.example.com/tools`，同时设置
+`api_url` 为 HTTP Job API 基址，例如 `https://memory.example.com/reme`。
+
+未知字段或无效值会使配置校验失败，Hook 会跳过并记录 `hook_failed`，不会回退到其他服务。
+关闭 `auto_memory` 会停止自动捕获和重试，保留已有队列；显式 MCP 工具仍可使用。
+修改服务地址不会把旧地址下的待提交对话发送到新服务。移除配置项即可恢复该项默认值。
+
+插件通过宿主管理的 stdio 连接进程转发 MCP，请确保启动宿主时的 `python3` 环境包含 FastMCP。
+如果 ReMe 服务运行在另一台机器或另一个 Python 环境，在宿主环境执行
+`python3 -m pip install "fastmcp>=3.1"`。Hook 本身仅使用标准库。
