In this ~11-minute walkthrough, I’ll show you exactly how to turn your n8n instance into a first-class MCP server so you can search, execute, and even edit workflows directly from tools like Claude Desktop, Cursor, and Claude Code. You’ll see why this native MCP layer is smoother, more stable, and way more “buttery” to work with than the open-source alternatives—especially when it comes to live-editing real production workflows. We’ll start by enabling MCP Access inside n8n, grabbing your instance-level MCP config and access token, and wiring it into Claude Desktop via a single JSON file. From there, I’ll demo how Claude can automatically discover your workflows, inspect their structure, and execute them end-to-end—complete with webhook triggers, LangChain/AI agent nodes, and responses flowing back in plain language. Then we’ll jump into Cursor, where I compare the original open-source n8n MCP with the new native instance-level MCP and show why the new one is dramatically better at editing workflows. To prove it, I intentionally build a broken chatbot workflow: a webhook → GPT-4.1 mini agent → memory → webhook response chain that’s missing critical pieces like the correct HTTP method, response mode, field mappings, and session ID wiring. Using only the n8n MCP server, I ask Cursor/Claude to execute it, watch it fail, and then let MCP iteratively patch the underlying JSON until the workflow fully runs—fixing IDs, modes, memory wiring, and credentials along the way. By the end, you’ll know how to: Turn your n8n instance into an MCP server with instance-level access Expose specific workflows (with metadata and descriptions) so AI tools reliably pick the right one Plug n8n MCP into Claude Desktop and Cursor using a simple JSON config Search, execute, and auto-debug workflows purely via MCP tools Safely use MCP-driven editing on production workflows while staying in control of what goes live If you’re using n8n as the backbone of your AI systems, this is how you connect it directly to your AI coding environment and assistants—so they can not only call your workflows, but repair and evolve them with you. ⏳ TIMESTAMPS: 00:00 – Intro: Why instance-level MCP in n8n actually matters 00:28 – Visual tour: MCP-enabled workflows and new icons in n8n 00:47 – Updating n8n & finding the new MCP Access settings tab 01:21 – Configuring MCP access: server URL, access token, and JSON 02:01 – Enabling workflows for MCP & adding rich descriptions/metadata 02:59 – Wiring n8n MCP into Claude Desktop via the JSON config file 03:43 – Demo: Searching and executing workflows from Claude using MCP 05:45 – Using the n8n MCP server inside Cursor (vs the open-source MCP) 06:36 – Building an intentionally broken chatbot workflow in n8n 07:59 – Asking MCP (via Cursor) to run the broken workflow and iterate 09:00 – Auto-fixing webhook mode, response behavior, and session ID 10:09 – Final run: working chatbot workflow and how MCP edited the JSON 10:47 – Best practices, production cautions, and closing thoughts #n8n #n8nmcp #MCP #ModelContextProtocol #ClaudeDesktop #CursorIDE #AIWorkflows #WorkflowAutomation #AIEngineering #DevTools #instancelevelmcp #ChatbotDevelopment #OpenAI #GPT41 #ClaudeAI #AutomationTools #nocode #claudecode
