_calculate_config_hash 在遇到非 JSON 序列化对象时对 json.dumps 降级保护，避免序列化崩溃； 4. 补齐相关功能的单元测试，并修正部分 Module 层的 import 格式。 --- .../package/yuxi/services/mcp/client_pool.py | 61 +++++++---

遗留凭据。 2. 修复并发与连接泄露：重构 proxy_service 以复用共享 httpx 客户端，并在 client_pool 中采用 Future 占位模式替代全局协程锁，提升启动并发效率。 3. 缓存优化：引入 cachetools，使用 LRUCache 与 TTLCache 替换无界字典，防止内存泄漏。 4. 数据库一致性修复：在 server_service 删除实例前提前清理 Redis 缓存，防止级联删除后遗失追踪句柄。 5. 测试修复：全面修复因 httpx.Timeout、过期 TTL 以及代理环境变量带来的测试失败问题。 --- backend/package/pyproject.toml | 1 + .../package/yuxi/services/mcp/client_pool.py | 146 +++++++++++-------

多鉴权编排与内部代理链路**：为 MCP 接入新增 `auth_config_json` 与 `mcp_connections` 绑定模型，支持 `bound_secret`、`custom_http_token`、`client_credentials`、`stdio_env`、`authorization_code` 等鉴权编排基础；后端补齐基于 Redis 的 access token 缓存、预刷新与 401 后自动删缓存重试能力，并新增 `/api/internal/mcp-proxy/{server_name}` 内部代理路由，将动态 HTTP MCP 的鉴权、续期 and 重试逻辑统一收敛到服务端；补齐用户/部门绑定连接缺失时的内部代理拒绝逻辑，避免个人级 MCP 连接被其他用户通过代理入口串用；同时让管理端 `/api/system/mcp-servers/{name}/tools` 与 `/tools/refresh` 也按当前管理员的 `user_id/department_id` 解析绑定连接，避免跨部门管理员在未授权情况下探测到 MCP 工具列表；新增 Redis 版次 + manifest 分级缓存，让 API/Worker 多进程场景下的 MCP 工具清单按 `server` / `connection` 分区同步失效，并避免旧 graph 中预加载 of managed tool 覆盖本轮实时鉴权加载结果；修复动态 HTTP 内部代理短期 JWT 被工具对象缓存固化、停用 MCP 仍可通过内部代理访问、更新 `auth_config` 后 runtime token 未立即清理的问题；统一 Agent 运行态与连接管理页的个人 MCP scope 语义，避免运行态使用数据库主键查找 `mcp_connections.scope_id` 导致个人连接不可用；补齐运行时鉴权 MCP 工具的执行阶段映射，避免模型已绑定 `getTicket` 等动态工具但 ToolNode 静态注册表无法执行的问题；审计并修复该链路隐患：通过 DynamicMCPTokenAuth 引入 15 秒 TTL 在内存缓存（含联动清除机制）解决 httpx 请求对 DB 的高频重复查询问题；修复 `_normalize_token_payload` 处理 naive datetime 的时区偏差问题以消除 token 无限自动刷新的 Bug；改进 `_calculate_config_hash` 哈希计算逻辑，对 json.dumps 增加 default=str 降级保护防止无法序列化而崩溃的问题；优化免密钥连接测试，在 binding_scope 非 inline 且配置未引用 `\${secret.xxx}` 变量时免去 connection 的强检验，允许直接进行测试和工具加载；在 `client_pool` 中实现长连接失效的断线清理机制，防止 anyio.ClosedResourceError 报错固化在缓存中；修复 mock MCP demo server 在 FastAPI 路由下返回值的 ASGI 响应冲突，将其重构为原生 ASGI App 路由，并在 Docker 中容器化部署；前端增加 `${context.work_id}` 快注按键并补齐后端 context.work_id 工号识别支持；修复未配置认证时前端发送空字典 `{}` 导致 Pydantic 400 校验错误的问题。 - 本次补充：明确 `YUXI_INTERNAL_MCP_PROXY_BASE_URL` 是动态 HTTP MCP 的内部鉴权网关地址；统一 runtime config 与代理入口的 active connection 强制规则，允许未引用 `${secret.xxx}` 的动态 MCP 无绑定连接运行；连接测试补齐 user scope 的 `work_id`，连接池 hash 忽略短期 `X-Yuxi-MCP-Proxy-Token`；补充 MCP 动态鉴权使用说明和开发手册。 - 本次补充：将个人级 MCP 连接配置收敛到用户设置弹框，普通用户仅可查看脱敏 MCP 信息并维护自己的 `user` scope 连接；管理员仍在扩展管理中维护 MCP 服务、共享连接与工具开关。 - - 本次补充：优化 MCP 连接管理体验，管理页连接区支持健康筛选、绑定对象搜索和分页；连接卡片统一展示凭据状态、生效范围、绑定对象与单一问题主动作，设置页沿用同一卡片语言但隐藏生效范围。 + - 本次补充：优化
