Bug Reports

Describe the Bug

Same as this bug: Cursor v1.3 not detecting mcp tools

Cursor should NOT be discarding all the tools it was just given via “tools/list” after it tries a “prompts/list” against a server without prompts.

Steps to Reproduce

Use any MCP server without the prompts/list implemented.

Expected Behavior

Ignores any errors form the “prompts/list” method

Operating System

Windows 10/11

Current Cursor Version (Menu → About Cursor → Copy)

Additional Information

The workaround in Cursor v1.3 not detecting mcp tools should not be marked as a solution - Cursor still has the bug, and it makes no sense to expect millions of MCP servers to add a “do nothing” function for a feature they don’t support, just so cursor goes back to working OK like it used to.

Does this stop you from using Cursor

No - Cursor works, but with this issue

I no longer have a way to test this, sorry.
Also - amusing - I did an update right before filing the bug - no idea why it didn’t get the current one.
Thanks for the rapid reply (and probably fix!)
