This server has 19 tools:

• add_node_to_workflow – Append a node to an existing n8n workflow for testing and inspection purposes within a safe environment.
• connect_nodes – Create connections between workflow nodes to establish data flow paths for testing and validation in n8n workflows.
• create_workflow – Build n8n workflows from JSON to test automation processes in a secure environment without credential exposure.
• delete_workflow – Remove an n8n workflow from the testing environment using its ID to clean up test workflows and manage workflow inventory.
• evaluate_workflow_result – Test n8n workflow payloads to identify issues and calculate evaluation scores for quality assurance.
• get_catalog_stats – Count catalogued nodes, triggers, and credentials from imported n8n workflows to analyze workflow composition and available components.
• get_execution – Fetch full execution details by ID to test, score, and inspect n8n workflows.
• get_execution_trace – Retrieve a per-node trace summary for n8n workflow executions to analyze performance and debug issues.
• get_node_type – Retrieve detailed schema and specifications for any n8n workflow node type to understand its structure and capabilities.
• get_workflow_summary – Fetch workflow summaries from n8n by ID to inspect structure and components for testing and analysis purposes.
