This is for anyone working with n8n workflows through the MCP protocol rather than the UI. It knows the difference between the two nodeType formats that'll trip you up (nodes-base.slack for validation, n8n-nodes-base.slack for workflow operations), pushes you toward detail="standard" instead of wasting tokens on detail="full", and maps out the discover-validate-update cycle that actually works. The smart parameters for IF/Switch branches are clever. Real time savers are the validation profiles and knowing that every workflow update auto-sanitizes all your nodes. Written by someone who's clearly debugged "node not found" errors enough times to document the patterns that matter.
