Not sure what is going on but when I try and leverage the MCP tooling to create lucid diagrams I receive the following error above. The other tool lucid_create_diagram_from_specification seems to be working.

It seems like the tools themselves have been updated. Is this document still up to date with the same names and functionality

Is the ‘Create a diagram with prompting’ still available or has it been officially removed?
