    • Use AI to generate a reasoning ontology graph (entities and the relations between them) from a topic, prompt, or text — e.g. "build an ontology on AI attention mechanisms"

    • Saved as a persistent InfraNodus graph by default and a link is returned; set saveGraph: false if the user asks not to save, or when you only need a one-off AI ontology overview of a topic for the current context that won't be reused later (the generated statements are returned directly without persisting)

    • modelToUse defaults to claude-opus-4.6 for richer ontologies; pick -mini/-lite variants (or gpt-4o-mini) for faster, cheaper generation

    • Returns the compact graph structure (knowledgeGraph) and analytics (main topical clusters, content gaps, top influential nodes, top relations, statistics) by default. Set includeGraph: false to save context space when only the ontology statements or insights are needed. Set includeAnalytics: false if you just need the raw ontology without graph-derived insights — keep it on whenever you want to understand the structure, gaps, or key concepts

17. analyze_llm_results

    • Ask an LLM to describe a topic and turn its response into a knowledge graph that reveals how the model frames it — main concepts, clusters, content gaps, and the relations between them

    • Use it to probe model bias, surface the implicit structure of an LLM's view on a subject, or compare how different models describe the same topic

    • modelToUse defaults to claude-opus-4.6; pick the model you actually want to study

    • modifyAnalyzedText controls how the LLM output is parsed: 'detectEntities' (default — mixed entities + words), 'extractEntitiesOnly' (entity-only graph), or 'none' (plain co-occurrence)

    • Saves the graph by default; set saveGraph: false for a one-off probe. Returns analytics by default and omits the raw graph (includeGraph: false) to keep responses compact — enable includeGraph when you also need nodes/edges

Knowledge Graph Memory Use Advice

InfraNodus represents any text as a network graph in order to identify the main clusters of ideas and gaps between them. This helps generate advanced insights based on the text's structure. The network is effectively a knowledge graph that can also be used to retrieve complex ontological relations between different entities and concepts. This process is automated in InfraNodus using the search and fetch tools along with the other tools that analyze the underlying network.

However, you can also easily use InfraNodus as a more traditional memory server to save and retrieve relations. We use [[wikilinks]] to highlight entities in your text to make your content and graphs compatible with markup syntax and PKM tools such as Obsidian. By default, InfraNodus will generate the name of the memory graph for you based on the context of the conversation. However, you can modify this default behavior by adding a system prompt or project instruction into your LLM client.

Specifically you can specify to always use a speciic knowlege graph for memories to store everything in one place:

Save all memories in the `my-memories` graph in InfraNodus.

Or you can ask InfraNodus to only save certain entities, e.g. for building social networks:

When generating entities, only extract people, companies, and organizations. Ignore everything else.

Installation

The easiest and the fastest way to launch the InfraNodus MCP server is to either use our server URL https://mcp.infranodus.com for the remote / web applications or to add a manual configuration to your LLM apps if you're running them locally.

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.

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

1. Prerequisites

• Create an account on InfraNodus if you don't have it already and get your InfraNodus API Key. We offer 14-day free trials.

1. Get the URL

• We currently use the following URL for our MCP server deployed in our infrastructure:

https://mcp.infranodus.com

2. Add the MCP server URL 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 OAuth in order to be able to access the InfraNodus MCP hosted on it.

4. Using 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.

2. Manual Setup: via NPX

You can deploy the InfraNodus server manually via npx — a package that allows to execute local and remote Node.Js packages on your computer.

The InfraNodus MCP server is available as an npm package at https://www.npmjs.com/package/infranodus-mcp-server from where you can launch it remotely on your local computer with npx. It will expose its tools to the MCP client that will be using this command to launch the server

For Claude Desktop / Cursor IDE:

Just add this in your Claude's configuration file (Settings > Developer > Edit Config), inside the "mcpServers" object where the different servers are listed:

{
	"mcpServers": {
		"infranodus": {
			"command": "npx",
			"args": ["-y", "infranodus-mcp-server"],
			"env": {
				"INFRANODUS_API_KEY": "YOUR_INFRANODUS_API_KEY"
			}
		}
	}
}

For Claude Code

To connect the InfraNodus MCP server to your Claude code, you can use this command. Make sure to provide the correct InfraNodus API key for your account:

claude mcp add infranodus -s user \
	-- env INFRANODUS_API_KEY=YOUR_INRANODUS_KEY \
		npx -y infranodus-mcp-server

3. Manual Setup: Launching MCP as a Local Server (for inspection & development)

1. Prerequisites

• Node.js 18+ installed

• InfraNodus API key (get yours at https://infranodus.com/api-access)

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:inspect
   npm run inspect

Note that build:inspect will generate the dist/index.js file which you will then use in your server setup. The standard npm run build command will only build a Smithery file.

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:

a. remote launch via npx:

{
	"mcpServers": {
		"infranodus": {
			"command": "npx",
			"args": ["-y", "infranodus-mcp-server"],
			"env": {
				"INFRANODUS_API_KEY": "YOUR_INFRANODUS_API_KEY"
			}
		}
	}
}

b. launch this repo with node, specify the absolute path to the repo + /dist/index.js:

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

Note: you can leave the INFRANODUS_API_KEY empty in which case you can make 70 free requests after which you will hit quota and will need to add your API key.

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:

a. remote launch via npx:

{
	"mcpServers": {
		"infranodus": {
			"command": "npx",
			"args": ["-y", "infranodus-mcp-server"],
			"env": {
				"INFRANODUS_API_KEY": "YOUR_INFRANODUS_API_KEY"
			}
		}
	}
}

b. launch this repo with node:

{
	"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 via npx:

INFRANODUS_API_KEY=your-api-key npx -y infranodus-mcp-server

or locally

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.

Legacy Setup via Smithery

InfraNodus server is also available through Smithery: a repository of MCP servers that has an easy-to-follow installation process for most LLM clients. You will need a separate accout at Smithery though.

• Create an account on Smithery.Ai (it's free and you can use your Google or GitHub login)

• Then go to the Smithery InfraNodus Server, click "Configure" at the top right, and add your InfraNodus API key there.

• Go to Smithery InfraNodus Server and get the URL link from Smithery https://server.smithery.ai/@infranodus/mcp-server-infranodus/mcp for the server or use one of their automatic setup tools for Claude or Cursor.

• You may need to get your separate Smithery API key and Smithery proile link to make this work.

For Cursor:

// e.g. Cursor will access directly the server via Smithery
"mcpServers": {
    "mcp-server-infranodus": {
      "type": "http",
      "url": "https://server.smithery.ai/@infranodus/mcp-server-infranodus/mcp?api_key=YOUR_SMITHERY_KEY&profile=YOUR_SMITHERY_PROFILE",
      "headers": {}
    }
  }

For Claude:

// Claude uses a slightly different implementation
// Fot this, it launches the MCP server on your local machine
"mcpServers": {
   "mcp-server-infranodus": {
			"command": "npx",
			"args": [
				"-y",
				"@smithery/cli@latest",
				"run",
				"@infranodus/mcp-server-infranodus",
				"--key",
				"YOUR_SMITHERY_KEY",
				"--profile",
				"YOUR_SMITHERY_PROFILE"
			]
		}
  }

Note, in both cases, you'll automatically get the YOUR_SMITHERY_KEY and YOUR_SMITHERY_PROFILE values from Smithery when you copy the URL with credentials. These are not your InfraNodus API keys. You can use the InfraNodus API server without the API for the first 70 calls. Then you can add it to your Smithery profile and it will automatically connect to your account using the link above.

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?"

Progress Notifications

For long-running operations (like SEO analysis), the MCP server supports real-time progress notifications that provide intermediary feedback to AI agents. This allows agents to:

• Track the progress of multi-step operations

• Display status messages to users

• Understand what's happening during lengthy analyses

Implementation

The server implements MCP progress notifications using:

1. ToolHandlerContext: All tool handlers can receive an optional context parameter containing the server instance and progress token

2. ProgressReporter: A utility class that simplifies sending progress updates with percentages and messages

3. Wrapped Handlers: Tool registration automatically injects the server context into handlers

Example Usage in Tools

import { ProgressReporter } from "../utils/progress.js";
import { ToolHandlerContext } from "../types/index.js";

handler: async (params: ParamType, context: ToolHandlerContext = {}) => {
	const progress = new ProgressReporter(context);

	await progress.report(25, "Fetching data from API...");
	// Do work

	await progress.report(75, "Analyzing results...");
	// More work

	await progress.report(100, "Complete!");
	return results;
};

The generate_seo_report tool demonstrates this pattern with 6 major progress checkpoints that provide detailed status updates throughout the multi-step analysis process.
