by Jimmy974
Enables programmatic creation and management of n8n workflows, including adding nodes, establishing connections between nodes, validating workflow specifications, and exporting complete workflow configurations.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@n8n Workflow Builder MCP Server create a workflow that fetches data from an API and saves it to a Google Sheet"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.

npx tscStart the server:
npm startUsage
The server provides a create_workflow tool that accepts a workflow specification:
{
"nodes": [
{
"type": "n8n-nodes-base.httpRequest",
"name": "HTTP Request",
"parameters": {
"url": "https://example.com",
"method": "GET"
}
}
],
"connections": []
}Configuration
Add the server to your MCP configuration:
{
"n8n-workflow-builder": {
"command": "node",
"args": ["/path/to/n8n-workflow-builder/dist/index.js"]
}

Disambiguation5/5
With only one tool, there is no possibility of ambiguity or overlap between tools. The single tool 'create_workflow' has a clear, distinct purpose that cannot be confused with any other tool in this set.
Naming Consistency5/5
The naming pattern is perfectly consistent as there is only one tool. It follows a clear verb_noun convention ('create_workflow'), which would be easy to maintain if more tools were added.
Tool Count2/5
A single tool is insufficient for a 'Workflow Builder' server, which implies capabilities like listing, updating, executing, or deleting workflows. This feels thin and under-scoped for the apparent domain of workflow management.
Completeness1/5
The tool surface is severely incomplete for workflow building. It only offers creation, with no ability to read, update, delete, execute, or manage existing workflows. This creates significant dead ends for agents trying to perform basic lifecycle operations.
