 # 任务目标
 
-分析一下"RemoteMcpToolsServiceImpl.java"的"getMisMcpToolMetadata"方法，为什么返回的是一个Empty List。调用的入口是"MisMcpToolMetadataCtl.java"的"doGetMisMcpToolMetadata"方法，传入的mcpServerIds是包含一个数值为2084832591415877633的集合。我在数据库执行SQL：
-```sql
-select * from mcp_serve where mcp_server_uuid = 2084832591415877633;
-```
-得到如下结果：
+分析`/project/stats/chart/chat`接口在处理请求参数`dimension`等于"year"的场景下，输出参数里面的y值不正确的问题。再顺便看看下面这几个接口是不是也有问题：`/project/stats/chart/token`、`/project/stats/chart/dislike`、`/project/stats/chart/user`、`/project/stats/chart/skill/usage`、`/project/stats/chart/feedback`、`/project/stats/chart/mcp/usage`、`/project/stats/chart/skill/usage`。

+## 开发规范

+参考文档:"E:\gitea\skills\mis-agent-spec\SKILL.md"。
+
+## 入口类
+
+ProjectStatsController.java

+## HTTP请求的输入和输出信息

-但是我发现doGetMisMcpToolMetadata返回的是1个空的集合，这是为什么？
