n8n-multi-instance
Agent skill from
Use when an n8n-mcp account targets more than one n8n instance — i.e. the `n8n_instances` tool is available, the user mentions multiple n8n instances or environments (prod vs staging, several teams or clients), several agents or chats work on one account in parallel, a workflow / datatable / credential / execution call returns an unexpected NOT_FOUND or reads data you don't recognize, or a call is refused with `INSTANCE_AMBIGUOUS` or `INSTANCE_NOT_FOUND`. Covers naming the target instance on each call with the `instance` argument, setting the default with `switch`, verifying the target before high-stakes work — credential writes above all — and recovering from misroutes and fail-closes. Always consult this skill before operating on a specific instance, before any credential create/update/delete on a multi-instance account, or when a call hits the wrong/empty data or an instance error.

1# Working with multiple n8n instances over MCP23When the `n8n_instances` tool is available, the user has **multi-instance mode** on: one MCP4connection can reach several n8n instances (e.g. `prod`, `staging`, or one per client/team).56There are two ways to say which instance a call should hit:78- **Name it on the call** — every n8n tool (`n8n_get_workflow`, `n8n_list_workflows`,9 `n8n_update_partial_workflow`, `n8n_manage_datatable`, `n8n_manage_credentials`,10 `n8n_executions`, `n8n_test_workflow`, `n8n_health_check`, …) takes an optional11 `instance: "<name>"`. It routes **that one call** and changes nothing else. **Prefer this.**12- **Set the default with `switch`** — `n8n_instances({mode:"switch", name})` sets the instance used13 by calls that *don't* name one.1415The default is shared more widely than it looks. On claude.ai (and other hosted connectors) one16connection serves **every chat and agent** using it, so a `switch` in one chat moves all the17others too — and their next unnamed call silently lands on your instance. A wrong target is18usually silent: a read returns the wrong data and a write lands in the wrong place. So name the19instance.2021If the `n8n_instances` tool is **not** present, the account is single-instance: ignore this skill22and use the n8n tools directly.2324> **Availability.** The `instance` argument needs hosted n8n-mcp backend 0.1.120+ / n8n-mcp25> 2.94.0+.
