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 has a clearly distinct purpose: workflow CRUD, execution management, connection check, and tag listing. There is no overlap or ambiguity between tools like activate/deactivate or create/delete.
All tools follow a consistent verb_noun pattern with underscores (e.g., activate_workflow, list_executions, check_connection). No mixed conventions or irregular naming.
12 tools is well-scoped for managing n8n workflows and executions. Each tool serves a distinct function without redundancy, covering the primary operations needed.
The tool set fully covers workflow lifecycle (create, get, update, delete, activate, deactivate) and execution operations (list, get, delete), plus connection check and tag listing. No obvious gaps for the domain.
