MCP resources support

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Currently, Cursor does not support resources (Example Clients - Model Context Protocol). However, when trying to use a stateless MCP Server that exposes resources, it will still try to subscribe, which, for a stateless server, results in a Missing handler for request type: resources/subscribe error even though subscription is not enabled.

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report.

This is a known bug. Cursor is currently ignoring the server-declared capability subscribe: false and still tries to send resources/subscribe requests. That shouldn’t happen when the server explicitly disables subscriptions.

The team is aware. Your report helps us prioritize it.

As a temporary workaround, if your MCP server framework allows it, you can add a no-op handler for resources/subscribe that just returns an empty response so the error doesn’t surface.

Let me know if you run into anything else.
