Hey, thanks for the report. This looks like a bug in how the IntelliJ ACP client renders tool call parameters, since Zed displays them correctly. The data is clearly being sent, it’s just not shown on IntelliJ’s side.
I’ve flagged this with the team. Could you share a few details to help with the investigation?
Thank you for your reply. Here are the additional details:
Cursor version
cursor-agent --version
2026.03.20-44cb435
IntelliJ IDEA version:
IntelliJ IDEA 2025.3.4 (IU-253.32098.37)
IJ plugin and version:
JetBrains AI Assistant (253.32098.66)
Also, thank you all so much for everything you’ve done. Your product has greatly improved our efficiency. We are also very grateful for your openness in providing the ACP functionality, which has allowed us to maintain our work habits.
The missing tool call parameters over ACP (the empty raw input, so IntelliJ couldn’t show which file was read or found) was fixed in a recent Cursor CLI update. Tool calls now get their real title and input as soon as the arguments are known.
Updating the Cursor CLI (cursor-agent) to the latest version should resolve this, and the extra npm wrapper shouldn’t be needed anymore. Let me know if you still hit it after updating.
