n8n-multi-instance

Working with multiple n8n instances over MCP When the n8n_instances tool is available, the user has multi-instance mode on: one MCP connection can reach several n8n instances (e.g. prod , staging , or one per client/team). Every other n8n tool ( n8n_get_workflow , n8n_list_workflows , n8n_update_partial_workflow , n8n_manage_datatable , n8n_manage_credentials , n8n_executions , n8n_test_workflow , …) runs against whichever instance this session is currently targeting . There is no per-call instance argument: you change the target only by switching. Target the wrong instance and a read returns the wrong data and a write lands in the wrong place — usually with no error (the one exception is an ambiguous credential write, which fails closed; see below). So target deliberately. If the n8n_instances tool is not present, the account is single-instance: ignore this skill and use the n8n tools directly. Golden rules Six rules. Each prevents a class of silent misroute.
