Server Configuration
Describes the environment variables required to run the server.
| Name | Required | Description | Default |
|---|---|---|---|
| N8N_API_KEY | Yes | Your n8n API key | |
| N8N_BASE_URL | Yes | The base URL of your n8n instance (e.g., http://localhost:5678) | http://127.0.0.1:5678 |
| DEFAULT_TIMEOUT_MS | No | Default timeout for workflow execution in milliseconds | 30000 |
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.

TDQS
Scored across 19 tools
Most tools have clear distinct purposes (e.g., list_* vs get_* vs create_*), but some overlap exists: list_triggers and list_node_types both list node-like entities; get_execution and get_execution_trace both fetch execution data though with different levels of detail; evaluate_workflow_result and test_workflow are similar, with the former adding evaluation. This could cause occasional misselection.
The naming follows a consistent pattern of verb_noun (e.g., list_triggers, connect_nodes, get_workflow_summary, create_workflow), with almost all using snake_case and standard CRUD verbs. The only minor deviation is the presence of both 'list_triggers' and 'list_node_types' which are similar but still follow the pattern, and 'connect_nodes' is descriptive. Overall, very consistent.
The server has 19 tools, which is at the upper edge of the 'well-scoped' range (3-15) but not excessive given the breadth of workflow management, catalog exploration, testing, and execution retrieval functionality. It feels slightly heavy but each tool addresses a specific need in the workflow lifecycle.
The tool set covers major workflow lifecycle operations (create, read, update, delete) along with comprehensive testing and execution analysis, and catalog exploration. Minor gaps exist: there is no explicit tool for 'disconnect_nodes' or 'remove_node', and no tool for listing all workflows (only get by ID), which could be a dead end for agents needing overview. But the core domain is well-covered.
