Walkthrough

The change adds a new client option function WithHTTPTransport in both client/sse.go and client/transport/sse.go. This function accepts an http.RoundTripper and returns a ClientOption that sets the Transport field of the internal http.Client used by the SSE client to the provided transport. Additionally, a new test case was added in client/sse_test.go to verify the functionality of this option by using a custom HTTP transport implementation that counts requests. No other logic or control flow changes were made.

Changes

File(s)	Change Summary
client/sse.go	Added WithHTTPTransport function to set a custom HTTP transport by assigning the provided http.RoundTripper to the client's internal HTTP client's Transport field. Added import of net/http.
client/transport/sse.go	Added WithHTTPTransport function to set the internal HTTP client's Transport to a provided http.RoundTripper.
client/sse_test.go	Added new test subcase "WithHTTPTransport" using a custom RoundTripper implementation that counts requests. Added assert package import.

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.

This feature is quite useful internally. Since it requires a custom transport to function properly, we'd really appreciate it if you could review this PR and let us know if any further changes are needed. @ezynda3

IMHO: might be better to give option to give users the flexibility to override the httpClient as in https://github.com/mark3labs/mcp-go/pull/109

Could you add a simple test just so its documented how this is used?
