Operating System

Distribution Method

Describe the issue

Getting error in latest update:

Error: MCP tool mcp__but-security__approval_prompt (passed via --permission-prompt-tool) not found. Available MCP tools: none

Downgrading to 0.16.10 gets it working again.

I also tried the latest nightly build and that seemed to have the same issue.

How to reproduce (Optional)

Try to do any claude code prompts and you'll see an error every time

Expected behavior (Optional)

Claude prompts should work.

Relevant log output (Optional)

Claude exited with non 0 error code

Error: MCP tool mcp__but-security__approval_prompt (passed via --permission-prompt-tool) not found. Available MCP tools: none
This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason:

Hey @alexanderjensen-source , sorry for the disruption.
Could you please test the following - see if you can (re)-install the GitButler CLI and redo the Codegen test.

[krlvi]

NB: i dont think the mitigation above would work, but I have a fix in the works

[krlvi]

Just to drop a note here that this regression is only reproducible if the setting "dangerously skip permissions" is disabled.

Still working on tracking down the root cause here

cc-ing you @Caleb-T-Owens

I also encountered this error. I haven't found a proper way to fix it. I don’t think it’s a CLI issue, because when I switch to "dangerously allow all," it works.

[Caleb-T-Owens]

Hi all! I'm currently working on this issue

[alexanderjensen-source]

Thanks for that. If you need any help testing I do have the project running from source as well.

[Caleb-T-Owens]

@alexanderjensen-source the has been landed in master if you want to try it out now. We are working on putting out a release now.

[alexanderjensen-source]

Looks like its working on the master branch -- thanks for the timely fix!
