概览

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), a workflow / datatable / credential / execution call returns an unexpected NOT_FOUND or reads data you don't recognize, or a credential create/update/delete is refused with an `INSTANCE_AMBIGUOUS` error. Covers choosing and switching which instance this MCP session targets, verifying the target before high-stakes work — credential writes above all — and recovering from misroutes and ambiguous-write 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_AMBIGUOUS` error.

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.

Discover first. Call n8n_instances({mode:"list"}) before acting so you know the instance names and which one is current.
Switch by name to your target before doing work on a non-default instance: n8n_instances({mode:"switch", name:"<instance name>"}). The match is case-insensitive.
Switch in its own turn. Never put a switch and a dependent operation in the same parallel tool-call batch. Calls in one batch have no guaranteed order, so the dependent call can be resolved against the previous instance before the switch's session state is visible. Switch, let it return, then operate.
Verify before high-stakes ops. Immediately before creating/updating/deleting credentials (and before destructive workflow edits), confirm current is the instance you intend — primary check is n8n_instances({mode:"list"}). The system fail-closes only the ambiguous credential case (rule 6); an explicit switch to the wrong instance still writes there silently, so this check is on you.
An unexpected NOT_FOUND is almost always a wrong-instance misroute, not a deletion. Don't recreate the object. Re-check the current instance and retry (see Recovery).
On INSTANCE_AMBIGUOUS, switch on this session, then retry. The system is refusing to write a secret because this session never picked a target itself. Comply — run switch here to confirm the instance, then retry the write. Don't work around it or retry blindly.

Core workflow

1. n8n_instances({mode:"list"})                      # see available[] + current + default
2. n8n_instances({mode:"switch", name:"prod"})       # bind THIS session to "prod"
   → returns { previous, current }; confirm current.name == "prod"
3. (do your work) n8n_list_workflows / n8n_get_workflow / n8n_manage_datatable / ...
4. Before a credential write or a delete:
   n8n_instances({mode:"list"})  → re-confirm current, THEN n8n_manage_credentials({action:"create", ...})

To move to another instance, just switch again. The whole session follows the switch.

The `n8n_instances` tool

Two modes (mode is required and enum-validated):

{mode:"list"} → { current, default, available }, no side effects.
- current and default are each one instance { id, name, url, isDefault } (or null).
- available is every instance, each with an extra isCurrent boolean. Match by name; never hard-code id.
{mode:"switch", name:"<name>"} → { previous, current }, and binds this session to the named instance. name is case-insensitive.

Error envelope (from the `n8n_instances` tool)

Every error returns { error: "<CODE>", message, … }. The ones you'll actually hit:

Code	When	What to do
`UNKNOWN_INSTANCE`	`name` matches no instance	Pick a name from the `available` list in the error payload and retry.
`NAME_REQUIRED`	`switch` with no `name`	Re-call with a `name` (the error lists the valid ones in `available`).
`MULTI_INSTANCE_DISABLED`	multi-instance mode is off	There's nothing to switch; use the n8n tools directly. The user can enable it at the n8n-mcp dashboard.
`NO_SESSION`	the request has neither an MCP session id nor a credential id	A selection has nowhere to land. Reconnect / initialize a session, then switch.
`UNKNOWN_MODE`	`mode` wasn't `list`/`switch`	Use `list` or `switch`.
`INVALID_CONTEXT`	server-side metadata missing	A server bug, not your input — report it.

Instance names can never be default, current, list, or switch (reserved), so you'll never see an instance literally named after a mode or field.

`INSTANCE_AMBIGUOUS` (from the credential-write path, not the tool)

A separate, higher-stakes error. It is not returned by n8n_instances — it's returned by the server when you call n8n_manage_credentials to create/update/delete a credential and the target instance is ambiguous: this session never switched on its own but inherited a switch made elsewhere (a fan-out / reconnect), pointing at a non-default instance. Rather than risk writing a secret to the wrong instance, the server blocks the write (it never reaches n8n, no quota is charged) and returns:

{
  "error": "INSTANCE_AMBIGUOUS",
  "message": "… the session issuing this request never switched there itself … Re-run n8n_instances({mode:\"switch\", name:\"…\"}) on this session to confirm the target …",
  "lastSelected": { "id": "…", "name": "…" },
  "default":      { "id": "…", "name": "…" }
}

Fix: decide which instance you actually want (lastSelected is the inherited switch, default is the account default), run n8n_instances({mode:"switch", name:"…"}) on this session, then retry the write. See rule 6.

How targeting behaves (mental model)

A switch binds this session to the chosen instance. The binding persists for the rest of the session and survives reconnects, idle, and backend deploys (~24h, the MCP session lifetime) — you should not need to re-switch before every call.
Other sessions / terminals are independent: switching here does not move them.
One session targets one instance at a time. There is no per-call instance argument; you change the target only via switch.
Reads and non-credential writes route to the currently-selected instance, silently — a misroute produces wrong data or a NOT_FOUND, not an error.
Credential writes are the one guarded case. They route the same way, except the server fail-closes the ambiguous state (a session that never switched, recovered onto a non-default instance) with INSTANCE_AMBIGUOUS. This is a safety net, not a substitute for rule 4: an explicit switch to the wrong instance still writes there.
If your selected instance is deleted (the user removes it mid-session), the next call silently falls back to your default instance — no error. So default's data appearing where you expected another instance's can look like "my data vanished." Re-list to see where you are.

Recovery playbook

Symptom	What it usually means	Do this
`INSTANCE_AMBIGUOUS` on a credential create/update/delete	This session never switched itself; the system won't guess which instance to write the secret to	Run `n8n_instances({mode:"switch", name:"<target>"})` on this session (the error names `lastSelected` and `default` — pick the one you want), then retry the write. Never retry blindly.
`NOT_FOUND` for a workflow/datatable/credential you know exists	You're pointed at the wrong instance — not that it was deleted	`n8n_instances({mode:"list"})` → check `current`. If it's not your target, `switch` and retry. Do not recreate the object.
A read returns empty or unfamiliar data	Wrong-instance read, or a silent fallback to `default` after your instance was deleted	`n8n_instances({mode:"list"})`, confirm `current`, switch if needed, re-read before drawing conclusions.
`UNKNOWN_INSTANCE` on `switch`	The `name` is wrong (typo, or you guessed)	Read the `available` names in the error and switch to one of those. Names are case-insensitive.
`n8n_health_check` reports an `instanceName` you didn't expect	This session is on a different instance than you think	`switch` to the intended instance, then proceed.
Repeated misroutes within one turn	You batched a `switch` with dependent work	Split them: `switch` alone, await the result, then operate one logical step at a time.

After any recovery switch, sanity-check with n8n_instances({mode:"list"}) (read current) as the primary signal. n8n_health_check also returns the resolved instance under details.instanceName, but it can be absent on some paths (legacy/chat), so treat it as a secondary confirmation.

Credential operations (highest stakes)

Credentials hold live secrets, and a misrouted credential write puts a secret on the wrong instance. The server protects the ambiguous case automatically — if this session never picked a target and inherited a switch to a non-default instance, the write fails closed with INSTANCE_AMBIGUOUS (rule 6) and never reaches n8n. But that net is narrow: a credential write on a session that did switch goes through to whatever instance it switched to, with no second guess. So:

Verify current immediately before n8n_manage_credentials create/update/delete — call n8n_instances({mode:"list"}) in the same short sequence, not 10 steps earlier where a later switch could have moved you.
On INSTANCE_AMBIGUOUS, switch on this session to confirm the target, then retry — don't work around it.
Credential reads (action:"list"/"get"/"getSchema") are not gated and don't write a secret, but a read off the wrong instance returns the wrong schema or list — so still verify current if the result looks wrong.
For the n8n_manage_credentials tool itself (CRUD shapes, getSchema discovery, never inlining secrets into text fields), see n8n-mcp-tools-expert.

Common multi-instance task: copy something between instances

To recreate a credential or workflow from instance A on instance B:

1. switch → A;  read the source (n8n_manage_credentials get / n8n_get_workflow)
2. switch → B   (its own call — never batched with the create below)
3. n8n_instances({mode:"list"})  → confirm current == B
4. create on B  (n8n_manage_credentials create / n8n_create_workflow)

Do each instance's steps in its own turn; never overlap switch → B with the create-on-B call (rule 3), and switch explicitly on this session before the credential write so it isn't ambiguous (rules 4 and 6).

Quick reference

See instances + where you are: n8n_instances({mode:"list"}) → { current, default, available }

# 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.

1. **Discover first.** Call `n8n_instances({mode:"list"})` before acting so you know the instance
   names and which one is `current`.
2. **Switch by name to your target** before doing work on a non-default instance:
   `n8n_instances({mode:"switch", name:"<instance name>"})`. The match is case-insensitive.
3. **Switch in its own turn.** Never put a `switch` and a dependent operation in the **same
   parallel tool-call batch**. Calls in one batch have no guaranteed order, so the dependent call
   can be resolved against the *previous* instance before the switch's session state is visible.
   Switch, let it return, *then* operate.
4. **Verify before high-stakes ops.** Immediately before creating/updating/deleting **credentials**
   (and before destructive workflow edits), confirm `current` is the instance you intend — primary
   check is `n8n_instances({mode:"list"})`. The system fail-closes only the *ambiguous* credential
   case (rule 6); an explicit switch to the **wrong** instance still writes there silently, so this
   check is on you.
5. **An unexpected `NOT_FOUND` is almost always a wrong-instance misroute, not a deletion.** Don't
   recreate the object. Re-check the current instance and retry (see Recovery).
6. **On `INSTANCE_AMBIGUOUS`, switch on *this* session, then retry.** The system is refusing to
   write a secret because this session never picked a target itself. Comply — run `switch` here to
   confirm the instance, then retry the write. Don't work around it or retry blindly.

4. Before a credential write or a delete:
   n8n_instances({mode:"list"})  → re-confirm current, THEN n8n_manage_credentials({action:"create", ...})
```

To move to another instance, just `switch` again. The whole session follows the switch.

**Fix:** decide which instance you actually want (`lastSelected` is the inherited switch, `default`
