Walkthrough

此次修改将 SSEClientTransport 的静态导入更改为在 SSEMCPServer 类的 start 方法中使用动态导入。模块在加载时不再预先加载 SSEClientTransport，而是在执行 start 方法时异步加载该模块。整体控制流程保持基本不变，仅调整了导入的时机。

Warning

There were issues while running some tools. Please review the errors and either fix the tool’s configuration or disable the tool if it’s a critical failure.

🔧 ESLint

If the error stems from missing dependencies, add them to the package.json file. For unrecoverable errors (e.g., due to private dependencies), disable the tool in the CodeRabbit configuration.

36-37: 优化了 SSEClientTransport 的导入方式

将静态导入改为动态导入是一个很好的改进。这样可以避免在模块加载时就预先加载 SSEClientTransport，而是在实际需要时（执行 start 方法时）才进行异步加载。这种懒加载方式有以下好处：

1. 减少初始加载时间和内存占用
2. 解决了可能存在的 ESM 模块循环依赖问题
3. 提高了代码的可维护性

这种修改与 PR 标题 "fix: sse mcp esm module" 所述的目的一致，解决了 ESM 模块相关的问题。

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
