InfraNodus MCP Server

A Model Context Protocol (MCP) server that integrates InfraNodus knowledge graph and text network analysis capabilities into LLM workflows and AI assistants like Claude Desktop.

Overview

InfraNodus MCP Server enables LLM workflows and AI assistants to analyze text using advanced network science algorithms, generate knowledge graphs, detect content gaps, and identify key topics and concepts. It transforms unstructured text into structured insights using graph theory and network analysis.

Installation

The easiest and the fastest way to launch the InfraNodus MCP server is to use the external provider, Smithery, and simply copy and paste the settings to the tool of your choice (e.g. Claude, Cursor, or ChatGPT).

You can also install the server locally, so you have more control over it. In this case, you can also edit the source files and even create your tools based on the InfraNodus API.

Below we describe the two different ways to set up your InfraNodus MCP server.

Easiest Setup: Smithery InfraNodus MCP Server (via HTTP/SSE)

  1. Prerequisites
  • Create an account on Smithery.Ai (it's free and you can use your Google or GitHub login)
  • Create an account on InfraNodus if you don't have it already and get your InfraNodus API Key. We offer 14-day free trials.
  • Then go to the Smithery InfraNodus Server, click "Configure" at the top right, and add your InfraNodus API key there.
  1. Get the URL of the InfraNodus Server from Smithery
  1. Add to to the Client Tool Where You Want to Use InfraNodus

  • Once you add the URL above to your tool, it will automatically prompt you to authenticate using Smithery (via Oauth) in order to be able to access the InfraNodus MCP hosted on it.

  • If your client does not support Oauth, you can click the link *Get the URL with keys instead** which you can use to authenticate without Oauth.

  • In the end, either Smithery or you yourself will add something like this in your MCP configuration file:

// e.g. for Cursor
"mcpServers": {
    "mcp-server-infranodus": {
      "type": "http",
      "url": "https://server.smithery.ai/@infranodus/mcp-server-infranodus/mcp?api_key=your_infranodus_api_key",
      "headers": {}
    }
  }
  1. Use InfraNodus Tools in Your Calls

  • To use InfraNodus, see the tools available and simply call them through the chat interface (e.g. "show me the graphs where I talk about this topic" or "get the content gaps from the document I uploaded")

  • If your client is not using InfraNodus for some actions, add the instruction to use InfraNodus explicitly.

Manual Setup: Local Server

  1. Prerequisites

  1. Clone and build the server:

    git clone https://github.com/yourusername/mcp-server-infranodus.git
cd mcp-server-infranodus
npm install
npm run build

  2. Set up your API key:

    Create a .env file in the project root:

    INFRANODUS_API_KEY=your-api-key-here

  3. Inspect the MCP:

    npm run inspect

Claude Desktop Configuration (macOS)

  1. Open your Claude Desktop configuration file:

    open ~/Library/Application\ Support/Claude/claude_desktop_config.json

  2. Add the InfraNodus server configuration:

    {
	"mcpServers": {
		"infranodus": {
			"command": "node",
			"args": ["/absolute/path/to/mcp-server-infranodus/dist/index.js"],
			"env": {
				"INFRANODUS_API_KEY": "your-api-key-here"
			}
		}
	}
}

  3. Restart Claude Desktop to load the new server.

Claude Desktop Configuration (Windows)

  1. Open your Claude Desktop configuration file:

    %APPDATA%\Claude\claude_desktop_config.json

  2. Add the InfraNodus server configuration:

    {
	"mcpServers": {
		"infranodus": {
			"command": "node",
			"args": ["C:\\path\\to\\mcp-server-infranodus\\dist\\index.js"],
			"env": {
				"INFRANODUS_API_KEY": "your-api-key-here"
			}
		}
	}
}

  3. Restart Claude Desktop.

Cursor Configuration

Other MCP-Compatible Applications

For other applications supporting MCP, use the following command to start the server:

INFRANODUS_API_KEY=your-api-key node /path/to/mcp-server-infranodus/dist/index.js

The server communicates via stdio, so configure your application to run this command and communicate through standard input/output.

Usage Examples

Once installed, you can ask Claude to:

  • "Use InfraNodus to analyze this text and show me the main topics"
  • "Generate a knowledge graph from this document"
  • "Find content gaps in this article"
  • "Retrieve my existing graph called 'Research Notes' from InfraNodus"
  • "What are the structural gaps in this text?"
  • "Identify the most influential concepts in this content"
