Cursor cannot see MCP tools with underscores / MCP subsetting per client

[daveio]

This is a well-known issue with Cursor. Tools with underscores in their name do not appear.

The server needs to mangle them to use - instead. I would suggest an arg to specify the host application. This would also allow us to subset MCPs per host, which is a critical use case for me and MCP Dockmaster is unsuitable without it.

Thanks for the product!

Update: uh, that's weird. MetaMCP uses underscores and the tools show up fine.

To be clear, I'm using the MCP inspector and Dockmaster does appear to present MCPs, but Cursor finds 0.
