Workflow Validation And Error Detection

via “multi-layer workflow validation with auto-fix suggestions”

A MCP for Claude Desktop / Claude Code / Windsurf / Cursor to build n8n workflows for you

Unique: Multi-layer validation framework (src/services/workflow-validator.ts) with pluggable validators for credentials, parameters, expressions, and node connectivity. Includes an auto-fix system that generates corrected workflow configurations with explanations, enabling AI assistants to self-correct generated workflows before deployment.

vs others: More comprehensive than n8n's built-in validation because it includes expression syntax checking and auto-fix suggestions; faster feedback than deploying and testing because validation is static analysis.
