shallowio.github.AvatarGaia/canvas-mcp · Verify this server
为岗位生成画布链接 + 会话 ID。用于用户需要"看得见的界面"（看报告/看商品/做检测）。参数：slug 必填；hostUserId 宿主用户标识（强烈建议带，会话归属和离线补推都靠它）；targetId 关爱/业务对象；app 指定画布页（如 aicare-kf）。返回 {url, session_id}——把 session_id 存下来，get_session_log / push_screen 都用它。会话在返回时已建立：现在就能 push_screen 给"还没来的人"备卡片，用户打开链接即补推；人打开后聊天/埋点都归到同一个 session_id。
