+- 分页默认 `page=1`、`size=20`，每页最多 100 条。 +- `sortBy` 支持 `priority`、`displayName`、`creationTimestamp`；方向为 `asc` 或 `desc`，默认 priority 升序。 +- `ungrouped=true` 包括未设置分组及引用不存在分组的链接，与 `groupName` 互斥。 +- `accessState` 支持 `UNKNOWN`、`CHECKING`、`ACCESSIBLE`、`INACCESSIBLE`；`backlinkState` 支持 `UNKNOWN`、`CHECKING`、`FOUND`、`MISSING`、`NOT_CONFIGURED`、`FAILED`。`UNKNOWN` 表示没有保存对应检测状态。 +- 更新中的空 `groupName` 取消分组；空 `description`、`logo`、`backlinkScanUrl` 清空该字段；省略字段则保留原值。不接受 `null` 代替清空操作。 +- 启用 RSS 必须提供或已经具有有效的 `feedUrls`。关闭 RSS 会异步清理订阅缓存。 +- 普通创建、更新不自动触发检测和 RSS 刷新，可以继续调用对应工具。申请审批则保留已有后端的自动检测、RSS 刷新流程。 +-

`read`、`favorite`、`readLater`、`hidden` | 仅修改指定文章明确提供的状态，各字段独立更新 | +| `mark_feed_items_read` | `linkName` 或 `all=true` | 将指定链接或全局可见未读文章标为已读，不修改隐藏文章 | + +RSS 列表使用游标分页，将响应的 `nextBeforePublishedAt`、`nextBeforeId` 分别作为下一页的 `beforePublishedAt`、`beforeId`，保留原筛选条件；`hasNext=false` 时停止。两个游标字段必须同时提供。文章返回标题、作者和有限长度摘要，不返回完整正文。 + +`set_feed_item_state` 的隐藏操作沿用现有存储行为：不存在的 ID 被忽略，返回实际更新数量；其他状态在 ID 不存在时返回 `NOT_FOUND`。多个状态更新不保证原子性。 + +## 接入与错误 + +工具通过 `McpToolProvider` 直接复用插件业务服务，编译期依赖 `run.halo.mcpserver:api:1.0.0-SNAPSHOT`，运行时由 MCP Server 提供 API。插件 JAR 不包含 MCP API 或 MCP Java SDK。 + +全部工具通过 `displayTitle`、`displayDescription` 提供中文管理界面文案，协议侧的 `title`、`description` 使用英文。每个工具均声明对象类型的 `outputSchema`，约束成功响应的 `structuredContent`，包括嵌套字段、可空值及批量操作的成功/失败分支。工具错误不套用成功输出 Schema。 + +MCP Server 在执行前校验密钥的工具白名单。查询、创建、修改、删除是独立工具，可以分别授权。工具注解区分本地查询、联网读取、写入和删除；注解本身不替代权限检查。 + +预期错误使用稳定代码，包括 `INVALID_ARGUMENT`、`NOT_FOUND`、`CONFLICT`、`FORBIDDEN`、`UNAVAILABLE`、`RATE_LIMITED`。批量操作通过逐项结果报告部分失败。检测状态筛选尚无索引，会在服务端读取候选链接并先筛选后分页，以保证总数和分页准确。 diff --git
