The n8n MCP Server is a Model Context Protocol (MCP) server designed to enable AI assistants to interact with and manage n8n workflows through natural language commands and API integration. n8n is a popular workflow automation tool, and this server acts as a bridge allowing AI assistants to programmatically control and execute workflows within n8n. The server supports various installation methods including npm global installation, source installation, and Docker container deployment, making it flexible for different user environments. The server requires Node.js 20 or later and an n8n instance with API access enabled. It can be configured using environment variables such as the n8n API URL, API key, and webhook authentication credentials. The server provides tools for workflow management, including listing workflows, retrieving workflow details, creating new workflows, and executing workflows via webhooks. The webhook execution feature supports basic authentication and allows triggering workflows by name with data passed from the AI assistant. Integration with AI assistants involves configuring the assistant to run the server's built JavaScript file, typically by specifying the command and arguments in a JSON configuration file. This setup enables AI assistants like VS Code with the Claude extension or the Claude Desktop app to communicate with the n8n MCP Server and control n8n workflows using natural language. The project includes detailed instructions for installation, updating, configuration, and usage, ensuring users can easily deploy and maintain the server. Debug logging can be enabled for troubleshooting. Overall, the n8n MCP Server facilitates seamless interaction between AI assistants and n8n workflow automation, enhancing automation capabilities through natural language processing and API integration.
