n8n Workflow Builder MCP Server
Build n8n workflows from text using AI - Built by FlowEngine
Turn natural language into production-ready, validated n8n workflows. This isn’t just another n8n context provider, it’s a complete workflow generation engine with built-in validation, auto-fixing, and architectural intelligence.
this MCP is built to provide validated n8n workflows — not just context.
- 13-Point Validation Engine - Catches errors before you import
- Auto-Fix Malformed Workflows — Automatically repairs common issues
- Architecture Recommendations — Suggests optimal workflow patterns
- Security Scanning — Detects credential leaks and vulnerabilities
- Performance Analysis — Identifies bottlenecks and optimization opportunities
- Real Parameter Schemas — Loaded directly from n8n packages for accuracy
- 600+ Registered Node Types — Only real nodes, no hallucinations
Result: Workflows that actually import and run on first try.
Quick start

Feature Details
13-Point Validation Engine
Every workflow passes through 13 validation checks before output:
- Node Type Validation — Verifies every node type exists in n8n
- Connection Integrity — Ensures all connections reference existing nodes
- Parameter Type Checking — Validates parameter types match node schemas
- Required Fields — Checks all required parameters are present
- Credential References — Validates credential configurations
- Expression Syntax — Checks n8n expression syntax (
={{ }}) - Position Validation — Ensures nodes have valid canvas positions
- Duplicate Detection — Catches duplicate node names
- Orphan Node Detection — Finds disconnected nodes
- Trigger Validation — Ensures workflows have proper entry points
- Loop Detection — Identifies potential infinite loops
- Output Mapping — Validates data flow between nodes
- Version Compatibility — Checks node version compatibility
Auto-Fix Malformed Workflows
When validation finds issues, the engine automatically repairs them:
- Missing positions → Auto-calculates layout on canvas
- Invalid node names → Generates unique, valid names
