Hi @plaskowski Is this PR ready for review? |
|
@skanehira I have been using it for a while from my fork. To be honest I don't plan to work on this soon so feel free to pick up the work to bring it to mergable state. |
|
@plaskowski is this what will enable Claude to reply to these kinds of comments? 
If so, what needs to be done to bring this to a mergeable state? Happy to try to help. |
yes
I will be honest - I have no idea as I have not yet read the contribution guideline. Most likely some test coverage and then maintainer review. The tool itself already works, I am using it (by using my fork built locally). |
|
@plaskowski, I've taken this up in another PR to get into a mergeable state. Can you describe how you've been using it locally so that I can do the same and test it myself? |
|
I was instructing the agent in simple terms. Initially it posted as general
comment but after few back and forth it understood that I want to reply in
thread (in don't recall what exact term I used)

Oops, sorry. I was trying to ask how you ran it locally. Was it by following this and running it in Docker? https://github.com/github/github-mcp-server?tab=readme-ov-file#prerequisites-1 |

Yes, I have build the docker image locally
