[REGRESSION] Hook response fields user_message / agent_message still ignored in Windows v2.0.77

Hooks are now completely broken! The IDE 2.1.42 says it’s calling the hook (see screenshot), however, it does NOT perform the call at all (my hook code is never run, and does not log anything), and does not give any error. Version: 2.1.42 (system setup) VSCode Version: 1.105.1 Commit: 2e353c5f5b30150ff7b874dee5a87660693d9de0 Date: 2025-12-01T02:18:26.377Z Electron: 37.7.0 Chromium: 138.0.7204.251 Node.js: 22.20.0 V8: 13.8.258.32-electron.0 OS: Windows_NT x64 10.0.17763 [pic_2025-12-0…

Is there a "change log" for each new cursor update?

This “PR Focussed” page only briefly mentions things on major new releases: Changelog · Cursor Is there one which lays out which bugs have been fixed for every release? It’s very disruptive to keep having to reinstall every day or two, only to discover that the bugs we 're waiting to be fixed, are still not fixed. @Cursor-team - do you read these? Can you please publish something so we can learn when you’ve fixed things we’re waiting for (MCP servers, hooks, etc)

Hooks still not working properly in 2.1.6

Where does the bug appear (feature/product)? Cursor IDE Describe the Bug Hook response regression bug is still present - the output from running hooks still does not arrive in the agent context. Cursor is NOT obeying its own spec as documented here: Hooks | Cursor Docs Steps to Reproduce Make a hook return something, ask agent if it can see the return. Expected Behaviour Should see it.

Cursor MCP server subsystem is totally SNAFU - Please can you prioritize some fixes!

“Drops all connections if one server fails” Could you share logs that show this behavior? Logs are attached.

Auto-reconnection to MCP servers is broken (runs multiple times in parallel, then fails). on/off works OK

I don’t recall presently, but I do sometimes use >1 window at the same time (and I am aware that each instance reconnects).

CRITICAL BUG: Cursor routing tool calls to wrong MCP servers

Where does the bug appear (feature/product)? Cursor IDE Describe the Bug Tool calls that should go to a named server, are wrongly being sent to a server that appears earlier in the mcp.json file even though the complete tool name is different. Steps to Reproduce Run 2 MCP SSE servers, such that two different tools on each are named: mcp_serverone_mytool mcp_servertwo_mytool calls to servertwo will always go to serverone by mistake Expected Behavior correct server should be used!
