### Where does the bug appear (feature/product)? Cursor IDE ### Describe the Bug The window terminated unexpectedly (reason: ‘crashed’, code: ‘5’) I use Atlassian MCP. and it started to crash with this prompt: “Let’s collect Jira Custom Required Fields per ticket type.” Actually, it crashes for any other prompt related to Atlassian MCP, but in 5% it could work. I noticed that it always crashed when I see “chat summarization” message. Issue appeared October 6 2025, few days before it was working fine ### Steps to Reproduce 1. Install Atlassian MCP and login 2. Type in chat “Let’s collect Jira Custom Required Fields per ticket type.” ### Expected Behavior application does not crash ### Screenshots / Screen Recordings ![cursor-crashed.png](https://us1.discourse-cdn.com/cursor1/original/3X/2/b/2b1114086a0323132626e6cb9ce79b441ffc3ef2.png) ### Operating System MacOS ### Current Cursor Version (Menu → About Cursor → Copy) Version: 1.7.38 VSCode Version: 1.99.3 Commit: fe5d1728063e86edeeda5bebd2c8e14bf4d0f960 Date: 2025-10-06T18:18:58.523Z (19 hrs ago) Electron: 34.5.8 Chromium: 132.0.6834.210 Node.js: 20.19.1 V8: 13.2.152.41-electron.0 OS: Darwin arm64 24.6.0 ### For AI issues: which model did you use?

Hey, thanks for the report. Let me know if this happens in your other projects as well. I don’t think it’s related to the mentioned MCP server, but we’ll check. ---

Yes, I’ve tried: 1. different project 2. copy current project to different directory 3. running with disabling extensions flag 4. clearing cache, npx cache ---

Atlassian’s MCP endpoint started returning 404 Missing sessionId responses. It looks like Cursor’s renderer or MCP handler doesn’t handle the missing sessionId gracefully and throws a TypeError during normalizePath, which tears down the renderer. ---

Reinstalling Cursor IDE from scratch doesn’t help as well. I’m just curious if somebody else has this issue. If I should continue research if something wrong with my environment or it’s just a bug. ---

I’m seeing the same behaviour with an MCP server I’m writing. As soon as “summarizing chat” appears, cursor crashes. With a prompt that doesn’t require summarization, it works fine. ---

getting this error every time now, after updating to 2.0.64 version, I believe before it was ~1.9 (before 2.0 at all). I am working with devcontainers and I do have Jira MCP. Turning off of Jira MCP doesn’t help. All projects are old. Mac OS, M1 ---
