Fix Real-World Coding Errors with GitHub Context through ghx and Cursor Composer

Install ghx with npm i -g @johnlindquist/ghx

https://github.com/johnlindquist/ghx

You've copied and pasted code, set up your project, and... error. "Stream is not readable." Sound familiar? Generic Google searches and outdated Stack Overflow answers often leave you more confused than when you started. You need more than just documentation; you need context. You need to see how real developers solve this exact problem.

This lesson shows you a better way to debug, using real-world GitHub examples and the power of Cursor's Composer.

Here's the workflow we'll cover:

  1. Identify the Error: You've already done this! You have a specific error message ("Stream is not readable") and the code that's causing it.
  2. Find Real-World Solutions with ghx: We'll use ghx, a tool for searching GitHub, to find actual projects that have encountered (and solved!) this same issue. No more generic advice – you'll see working code.
  3. Consolidate and Analyze: ghx brings those relevant code snippets into a single, easy-to-read file.
  4. Leverage Cursor's Composer: We'll use Cursor's Composer to directly interact with the examples and your problematic code. Paste in your error, reference the ghx-generated file, and ask targeted questions like:
    • "Based on these examples, how should I modify my code to fix the 'stream is not readable' error?"
    • "What's the common cause of this error in the context of an MCP server?"
    • "Show me the specific lines in the examples that handle stream readability correctly."
  5. Fix the Error: Implement the solution using this workflow.

Instead of guessing, you'll learn directly from proven solutions. You'll gain a deeper understanding of your issue and how to troubleshoot it effectively. This approach transforms debugging from a frustrating hunt into a targeted learning experience.

[00:00] So I was following this guide by copying and pasting code into my project like any good developer does to set up a model context protocol server. And I got to the point where I set up the code, I installed the packages, and it was time to run pnpm start. Now the way to check on this is on port 3001. Once you have the inspector you click connect and I ran into this error where the stream is not readable. Now this is one of those reasons why I built ghx which I'll run here and I'm going to pass in the package name and I'm going to pass in the fact that we're using the server, so the server transport rather than the standard I o transport, and I'll hit enter here and this is going to go fetch 50, by default 50, versions of a model context protocol server that other people have shared through GitHub.

[00:47] So it's scraped all the examples and brought them into this single file. Now once the file opens you'll see it only found seven results and so what I'm going to do this time is you can see it kind of crops out these code snippets. So when you look at these there's only little bits of code in here. I'm going to make sure that we pass in the dash dash context to bring in pretty much the entire file. I'll say 200 which means 200 lines above and below where the matches are in the file.

[01:12] So this time we'll have a lot more code available whereas before it cropped a lot. You can see this file has 3, 800 lines, whereas the other file only has 500 lines. Then I could open Composer with Command-I, I can reference my index with at index, and I can paste in my error into here and say based on the examples I provided, please fix my implementation. To fix the stream is not readable error. I'll go ahead and hit enter.

[01:43] And it says it notices that in the examples the key is messages. When using JSON it needs to pass the pre-parsed body. So it's going to go ahead and fix that for me. I'll go ahead and click accept. We'll PNPM start, the server is running again, and now once we click connect everything is working, we're connected, and we can list the resources and see what we have available inside of our MCP server.

[02:05] So again, this is the key reason I built the GHX tool. It saves me from a lot of those scenarios of Googling stream is not readable. This saved me from doing something like Googling stream is not readable with MCP, where the top results are stack overflow from 2020 to 2018 or even using like an AI service where you'd say like how do I fix this and you don't know exactly what to search for because you'd have to include all of your code and include all of that context. It's much easier just to bring in a bunch of examples into what you're currently working on and say, hey compare this to all these working examples other people provided and just follow their patterns. And you can see this answer doesn't really have anything to do with what I was looking for.

[02:46] I could try copy and pasting this and going in here and trying to explain it and keep iterating on it. But again it just feels so much more simple to have those examples in my editor, tell Composer to just fix it based on the examples.
