Started building this, got 20% done, then found out n8n already has an official MCP for docs

It’s true that n8n has converted its documentation into an MCP server. This isn’t just a chat agent on their website, but a full MCP that you can link to any AI and get free AI answers based on the n8n docs.

n8n is using an agent service called “Kapa” and their MCP service for n8n is available at https://n8n.mcp.kapa.ai/. You just link that URL and auth your kapa account (just use google auth with free plan), and you’ll get an MCP for the n8n docs, as shown in the image, which can help any AI agent using the latest n8n documentation.

Here’s an example MCP config:

    {
      "mcpServers": {
        "n8n-docs": {
          "type": "STREAMABLE_HTTP",
          "url": "https://n8n.mcp.kapa.ai/"
        }
      }
    }

Or

{
  "mcpServers": {
    "n8n docs": {
      "command": "uvx",
      "args": [
        "mcp-proxy",
        "--transport",
        "streamablehttp",
        "https://n8n.mcp.kapa.ai/"
      ],
      "env": {
      }
    }
  }
}

or using GUI like Claude Connector:

Pro tip: We use MetaMCP to manage MCP servers into one endpoint. and i have deployed n8n mcp server there and it worked too:

i am going to use Metamcp to make n8n docs search available as action in ChatGPT plugin n8n assistant with this solution and it’s free like n8n selfhosted, you can do same if you’re looking for n8n docs up-to-date and easy to manage with client resources.

Another thing to keep in mind is that n8n already maintains an LLM index for all its docs at this link: https://docs.n8n.io/llms.txt. This is an AI-indexed version of all their documentation pages share it with your A.I instructions and it will understand where to search in docs when need something.
