Hi All,
I have installed the mssql extension in cursor, but I get the below error. I have already tried a clean in stall, rebooted etc. Does anyone have any idea?
the error is:
Error running command mssql.addObjectExplorer: command ‘mssql.addObjectExplorer’ not found. This is likely caused by the extension that contributes mssql.addObjectExplorer.
I’m getting the same exact error with mssql extension today, SQLTools works fine though. Let me know if you figured out anything, thanks.
EDIT 2: Managed to get my hands on th vsix file, so now the version is up to date but the error persists.
EDIT 1: I noticed one thing, when I install the extension in Cursor, I get version 1.9.0, but in vs code the version is 1.34
Still no luck here, I have no more things to try and reached out to support
getting this same error now, I had used the extension in the v0. version of cursor and it worked
I am getting the same error. Is there any resolution?
Nope still no solution, I reached out to support again but complete radio silence. I have now pivoted to visual studio code, with github co-pilot. You lost a customer cursor
Almost 2 months since the OP; same problem. I tried the extension that comes on top when I run a search for SQL Server in the extensions marketplace. It’s called ms-mssql. A publisher name is not available.
I encountered this issue when I tried to install the extension directly from the Cursor marketplace. My IT team resolved this issue by first installing the extension in Visual Studio Code and then importing it into Cursor.
It how I did it as well, did not solve it, tried it all kinds of ways, no results and support is non existent.
I’m using the pselling’s trick and it works for me!. I completely removed the extension on cursor, installed on VSC and after that manually imported on cursor again (settings, general, import setting from VSC)
It’s 09/17/2025 and I’m getting the same issue. But my IT Dept is from the stone age and has blocked CoPilot. Without Cursor I have to paste into browser ChatGPT and paste it back. Cursor worked fine and then I got a new Work PC. I tried unistalling everything, deleting cache, deleting all mssql files I could find on the migrated profile… reinstalled VS, set it up, works fine, reinstalled Cursor, imported settings… nothing.
Error running command mssql.addObjectExplorer: command ‘mssql.addObjectExplorer’ not found. This is likely caused by the extension that contributes mssql.addObjectExplorer.
Support just ignores me, i have now asked for multiple updates. In the end we decided to go to github for bussines, combine that with VS code and use github AI, works like charm! Sorry cursor but you lost a customer, and I won’t recommend you as a mature development tool.
On VS Code, the version that works is SQL Server (mssql) - Visual Studio Marketplace (v1.36.0) but the version cursor uses is Open VSX Registry (v1.9.0). The VS Code version works fine but the Cursor one does not. I uninstalled the cursor version from my app and downloaded the VS Code version:
curl -L "https://ms-mssql.gallerycdn.vsassets.io/extensions/ms-mssql/mssql/1.36.0/1757682167555/Microsoft.VisualStudio.Services.VSIXPackage"
-o \~/Downloads/ms-mssql.mssql-1.36.0.vsix
then I installed that version into Cursor:
cursor --install-extension ~/Downloads/ms-mssql.mssql-1.36.0.vsix
I then restarted Cursor and now have a working version! If you do this, remember to turn off ‘Auto Update’ on the extension.
You can then import your VS Code settings into Cursor and that will port over any pre-stored connections you already have there.
