Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
This server publishes no instructions, or was last inspected before Glama recorded them.

Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| list_workflowsA | List workflows on the n8n instance. Returns id, name, active state, tags and dates. Supports cursor pagination. |
| get_workflowA | Get a full workflow by ID, including nodes, connections and settings. |
| create_workflowA | Create a new workflow (created inactive; use activate_workflow to enable it). 'nodes' and 'connections' are JSON in n8n's standard export format. |
| update_workflowA | Replace an existing workflow (PUT). Pass the full workflow JSON (typically the result of get_workflow with modifications); read-only fields (id, active, tags, dates) are stripped automatically. |
| activate_workflowA | Activate a workflow (starts running on its triggers). |
| deactivate_workflowA | Deactivate a workflow (stops responding to its triggers). |
| delete_workflowA | Permanently delete a workflow. ⚠️ Irreversible — confirm with the user before using. |
| list_executionsA | List workflow executions. Useful for debugging: filter by status ('error', 'success', 'waiting') or by workflowId. |
| get_executionA | Get the details of an execution. With includeData=true it returns per-node data (can be very large) — ideal for diagnosing errors. |
| delete_executionA | Delete an execution record. ⚠️ Irreversible. |
| list_tagsB | List the tags available on the n8n instance. |
| check_connectionA | Verify that the n8n instance responds and the API key is valid. |

TDQS
Scored across 12 tools
Each tool targets a distinct operation: activation, CRUD for workflows, execution management, tag listing, and connection check. No ambiguity between tools with similar verbs (e.g., activate vs. create vs. update) due to clear resource differentiation.
All tool names follow a consistent verb_noun convention in snake_case (e.g., activate_workflow, list_executions, check_connection), making the toolset predictable and easy to navigate for an agent.
With 12 tools covering workflow CRUD, activation, execution management, tags, and connection verification, the count is well-scoped for the n8n domain. Neither too few nor excessive.
The toolset provides comprehensive lifecycle coverage for workflows and executions. A minor gap is the absence of a manual trigger/run tool, but the core operations are fully covered.
