AI Evaluation Report

Total Score: 7/10

The agent demonstrates a strong capability in managing and executing workflows within the n8n environment, particularly in activating workflows and providing detailed information about them. However, it struggles with creating new workflows due to missing required properties, indicating a limitation in handling incomplete requests. Additionally, the agent's response to setting up the n8n-mcp-server lacks specific technical details, which is crucial for comprehensive guidance. Despite these shortcomings, the agent effectively retrieves and displays workflow details, showcasing its strengths in workflow management and execution. Overall, the agent's performance is satisfactory but could be improved with better handling of workflow creation and more detailed setup instructions.
