mcp-n8n-workflow-builder

What problem does it solve?

Many automation tasks require producing correct n8n workflow JSON manually, which is error-prone and tedious; this Skill exposes a programmatic MCP tool that generates and validates n8n workflows from simplified node-and-connection specifications to speed up automation and reduce mistakes.

Core Features & Use Cases

• MCP tool interface: Exposes a create_workflow tool that can be called over the MCP protocol to generate workflow JSON for Claude or other LLM integrations.
• Builder abstraction: Define nodes and connections in a compact specification and let the builder produce properly structured n8n JSON with node positioning.
• Validation and error handling: Uses JSON Schema-like input validation and standardized MCP errors for predictable failure modes.
• Use Case: Automation engineers can programmatically generate webhook → transform → HTTP request workflows for rapid prototyping, CI/CD pipeline creation, or integrating LLM outputs into n8n.

Quick Start

Use the mcp-n8n-workflow-builder MCP server to create an n8n workflow by providing a JSON object with nodes and connections.
