n8n MCP Server

Example Use Cases

• 1

  Validate n8n workflows against best practices (naming, error handling, security, performance, and documentation) before deployment.

• 2

  Generate NextJS integrations from n8n workflows, including API routes, OpenAPI/Swagger specs, TypeScript types, and a client API for easy consumption.

• 3

  Manage n8n workflows programmatically (list, fetch, create, update, delete, export, import) and interact directly with the n8n API.

Description

This project is an open-source Master Control Program (MCP) for n8n that offers workflow validation (naming, error handling, security, performance, documentation), NextJS integration generation (API routes, OpenAPI/Swagger, TypeScript types, API client), and direct interaction with the n8n API for listing, creating, updating, exporting and importing workflows. It includes ready-made workflow templates (e.g., Google Calendar) and utilities to enforce best practices across automation projects. The server can be run locally and integrated with tooling like Claude Desktop for developer workflows. It is intended to streamline development, improve reliability, and simplify integration of n8n automations into NextJS applications.
