MCP: Connecting to remote server with OAUTH partially succeeds

[Julton (Anders Julton)]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

I am able to connect to a remote MCP server using OAUTH, but not able to view or deselect tools due to error in output. Agent confirms that it has access to the server and its tools.

# mcp.json
{
	"mcpServers": {
		"Snowflake": {
			"url": "https://<redacted>"
		}
	}
}

Steps to Reproduce

This is a private MCP server and the steps for creating it are too involved to write up here.

Expected Behavior

Able to view and deselect tools after connecting to remote MCP server.

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report. This is a known issue with remote MCP servers, and a fix is in progress.

For now, you can use project rules to limit which tools the agent uses.
