n8n-mcp-workflow-builder

What problem does it solve?

It helps you design correct n8n workflows without guesswork by letting you discover nodes/templates, configure them precisely, and validate the resulting workflow before deploying.

Core Features & Use Cases

• Workflow template discovery: Find suitable workflow templates by task, metadata, keywords, or node types to kick-start automation design.
• Node & node-property configuration: Search for nodes (with examples), retrieve detailed documentation, and generate valid configurations using real node schemas.
• Validation & deployment guidance: Validate nodes/workflows (including expressions) and support creating, updating, testing, and auto-fixing workflows on your n8n instance.

Use Case Example: You need a webhook-driven Slack notification workflow that posts messages with the correct channel and validates all node connections—use templates first, then discover the exact trigger and Slack nodes, validate, deploy, and test.

Quick Start

Tell the assistant: "Build an n8n workflow that receives a webhook and sends a Slack message, then validate the nodes and connections before creating it on my n8n instance."
