n8n-mcp broke 7k stars ⭐⭐⭐ and just got a major reliability upgrade - your AI agents now catch and fix workflow errors automatically even better. 👇
📰 What's new:
👉 Automatic Error Detection & Fixing - n8n-mcp now identifies and corrects common workflow issues: missing webhook paths, incorrect expression formats, wrong error handler connections, and node type typos
👉Smart Node Corrections - Handles the classics: "HTTPRequest" → "httpRequest", "slak" → "slack", deprecated package prefixes, and suggests alternatives with confidence scoring. Only auto-applies fixes above 90% confidence
👉Preview-First Approach - New n8n_autofix_workflow tool lets you see what will be fixed before applying changes. Choose specific fix types or let it handle everything automatically
👉Expression Validation System - Three-tier validation catches missing '=' prefixes, validates bracket matching, and detects common mistakes like template literals before they break your workflows. So no mo manual switching from "Fixed" to "Expression" in the n8n UI 👉Resource Locator Intelligence - Smart suggestions for GitHub repos, Slack channels, and other resource identifiers with confidence-based recommendations
The real impact: AI agents spend less time debugging syntax issues and more time building the automation logic you actually need. Your workflows are significantly more likely to work on first deployment.
