What is the n8n MCP Server?

The n8n MCP Server is a middleware service that allows AI systems (such as ChatGPT, Claude, etc.) to directly interact with the n8n workflow automation platform through the Model Context Protocol (MCP). You can use natural language instructions to have the AI manage, execute, and monitor n8n workflows for you.

How to use the n8n MCP Server?

Simply install the server and configure the n8n connection. Your AI assistant can then list workflows, view details, execute workflows, and obtain results for you, as easy as having a tech-savvy virtual assistant.

Applicable scenarios

Suitable for scenarios that require combining AI with automated workflows, such as triggering business processes through a chat interface, having AI automatically handle workflow exceptions, and querying workflow execution status using natural language.

Main features

Workflow listView all available workflows in the n8n instance
Workflow detailsGet detailed configuration information for a specific workflow
Execute workflowTrigger workflow execution and pass in required parameters
Execution historyView past execution records and status of workflows
Activate/DeactivateEnable or disable workflows without manual operation

Advantages and limitations

Advantages
Manage workflows using natural language without technical knowledge
Seamlessly integrate AI capabilities with automated workflows
Support full workflow lifecycle management including parameter passing and result retrieval
Be compatible with multiple LLMs and AI agent systems
Limitations
Require pre - configuration of n8n API access permissions
Complex workflows may require additional parameter descriptions
Execution results depend on the design of the n8n workflow itself

How to use

Install the service
Install the MCP server via npm or Docker
Configure the connection
Set the n8n instance URL and API key in the.env file
Start the service
Run the server to make it ready to receive MCP requests
Connect to AI
Add the MCP server endpoint to your AI system configuration

Usage examples

Automatically process customer requestsWhen a customer submits a request through a chatbot, automatically trigger the order processing workflow in n8n
Workflow status queryQuery the recent execution status of a specific workflow using natural language
Parameterized workflow executionDynamically pass in required parameters when executing a workflow
