I made my own MCP server. (Python3, mcp>=1.0,<2)
It works very good with Goose 1.49 but after I updated to Goose 1.50 it breaks.

Goose shows me an error:
```
failed to initialize MCP client: uncorrelated error response: expected id 0, error response carried server-error
```

My MCP server shows an error:
```
[09/10/26 13:35:39] INFO Created new transport with session ID: a25c5d78f3c84167a1a86e0c86bf663a streamable_http_manager.py:302
INFO: 10.0.0.207:54932 - "POST /macrotracker/mcp HTTP/1.1" 400 Bad Request
```
If you want to see it, it available on https://github.com/DrMoriarty/ru-finance-mcp

**Expected behavior**
It worked with 1.49 and I expect that it will works with 1.50 also.

**Please provide the following information**
- **OS & Arch:** MacOS 14.7.4 (23H420)
- **Interface:** UI
- **Version:** 1.50 (latest)
- **Extensions enabled:** My own MCP server

**Additional context**
Add any other context about the problem here.

Do not begin implementation until the issue reaches **Ready** on the [Goose Issues board](https://github.com/orgs/aaif-goose/projects/1).

这个 issue 涉及 Goose 1.49 和 1.50 版本之间的 MCP (Model Context Protocol) 服务器兼容性。首先检查 Goose repository 中的 MCP 客户端初始化代码，可能位于类似 'mcp/' 或 'src/mcp/' 的目录中。查找版本之间错误处理或 ID 关联方面的变更。用户的 MCP 服务器使用 Python 编写，可在 https://github.com/DrMoriarty/ru-finance-mcp 获取；在本地测试交互。 “完成”表示 MCP 服务器能够在 Goose 1.50 中运行，且不会出现 'uncorrelated error response'。
