What's Wrong?
When using a MCP with prompts, I can see the list of prompts when I type / . The MCP prompt also has a title and Claude code show it correctly. However, when I select the prompt (which has a blank space on it), then Claude code returns the error "unknown slash command". The title should be used to display only, but it seems that Claude code is sending the title rather than the name. Not sure if the issue is due to a blank space in the title or Claude code sending the title rather than the name.
What Should Happen?
Claude should be able to invoke the slash command when titles are specified in prompts
