Writing an n8n workflow by hand means knowing the exact parameter names of hundreds of nodes, and that is precisely what a model gets wrong. This server indexes the node catalogue with documentation and property schemas, validates a proposed workflow before it is saved, and can create or update workflows on a connected n8n instance. The validation step is the reason it works: an invalid node parameter is caught in the loop rather than at run time.
