Expose SSE server as HttpHandler

[ezynda3]

Summary by CodeRabbit

• New Features

  • Enhanced server request handling to support real-time event streaming and messaging endpoints, ensuring clear responses for unhandled routes.
  • Streamlined server initialization process by integrating functionality directly into the main server function.

• Tests

  • Expanded automated tests to verify the new HTTP handling functionality, including middleware integration and custom routing scenarios.

Walkthrough

The pull request introduces a new method ServeHTTP to the SSEServer in server/sse.go, implementing the http.Handler interface. The method routes requests by URL path: /sse invokes handleSSE, /message invokes handleMessage, and other paths return a 404 error. Additionally, new tests in server/sse_test.go verify the HTTP handler functionality, its integration with middleware, and its behavior when used with a custom HTTP multiplexer. Furthermore, the MCPServer struct has been removed in examples/everything/main.go, with its functionality integrated into the NewMCPServer function and methods converted to standalone functions.

Changes

File(s)	Change Summary
server/sse.go	Added ServeHTTP method to SSEServer for dispatching requests to /sse, /message, or responding with a 404 error for unknown paths.
server/sse_test.go	Introduced new tests for verifying the server as an HTTP handler, including middleware handling and operation with a custom HTTP multiplexer.
examples/everything/main.go	Refactored MCPServer structure; removed the struct and integrated its functionality into NewMCPServer. Converted methods to standalone functions.

Poem

Hop, hop, in a code-filled glade,
I scan the paths that now are made.
/sse and /message in line,
Testing flows so crisp and fine.
With each new route I joyfully play—
A rabbit's code dance in springtime day!

🪧 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.

152-171: Consider removing unused function.

The runUpdateInterval() function contains only commented-out code and is never called. Since it doesn't provide any functionality, consider removing it entirely to improve code cleanliness.

---

371-390: Consider removing commented-out function.

The commented-out function handleSampleLLMTool is not being used. For code cleanliness, consider removing it or documenting why it's being kept.

31-129: Good refactoring of MCPServer implementation.

The custom MCPServer struct has been effectively replaced with a direct use of server.MCPServer. This simplifies the code by removing an unnecessary abstraction layer, making the implementation more straightforward and maintainable.

---

328-330: Clean implementation of standalone ServeSSE function.

The ServeSSE function nicely encapsulates the SSE server creation logic, accepting an MCPServer instance and returning an SSEServer. This aligns well with exposing the SSE server as an HTTP handler as intended in the PR.

---

433-446: Well-structured main function.

The main function has been cleanly updated to work with the new architecture. It now uses the standalone ServeSSE function and properly handles both SSE and stdio transport options.
