n8n Workflow MCP Server

n8n Workflow MCP Server is an MCP server that connects AI assistants like Claude Desktop and Cursor to n8n workflow management and validation tools. Built with Go, it provides developers and automation engineers with programmatic capabilities to inspect, search, and validate n8n workflow schemas directly inside their coding environments. Users can search through n8n nodes by keyword, locate community templates, and check workflow JSON files for syntax errors before running them in production environments. The server includes multilingual support across Korean, English, Japanese, Vietnamese, Traditional Chinese, and Thai, translating tool parameters and descriptions into the selected language. It supports both a standalone binary mode containing embedded node data and a filesystem mode for development with dynamic external files. By handling syntax verification and node lookups natively, the server helps technical teams build reliable automation pipelines without manually switching between editors and n8n web interfaces.
