N8n MCP Overview

AutomateLab-tech/n8n-mcp MCP server connects AI agents to n8n for workflow generation, linting, execution diagnosis, semantic diffing, and live-instance management. Stateless tools accept workflow or execution JSON, while live tools use the n8n API to list, retrieve, create, activate, and inspect workflows and executions. Reach for it when an agent needs to produce importable n8n JSON, catch configuration problems, investigate dropped items, or manage workflows through a configured n8n instance. It also includes a TypeScript custom-node scaffold tool and a Claude Code skill.

Primary Use Cases for N8n MCP:
  • Generate an n8n workflow from a plain-English description
  • Lint workflow JSON before importing it into n8n
  • Diagnose an execution where items disappear between nodes
  • Compare a deployed workflow with a local version
