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.

Available on npm: https://www.npmjs.com/package/infranodus-mcp-server

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.

Features

You Can Use It To

• Connect your existing InfraNodus knowledge graphs to your LLM workflows and AI chats
• Identify the main topical clusters in discourse without missing the important nuances (works better than standard LLM workflows)
• Identify the content gaps in any discourse (helpful for content creation and research)
• Generate new knowledge graphs from any text and use them to augment your LLM responses
• Save and retrieve entities and relations from memory using the knowledge graphs

Available Tools

1. generate_knowledge_graph

   • Convert any text into a visual knowledge graph

5. generate_topical_clusters

   • Generate topics and clusters of keywords from text using knowledge graph analysis
   • Make sure to beyond genetic insights and detect smaller topics
   • Use the topical clusters to establish topical authority for SEO
   • Returns AI-generated overviews of the topical clusters (topicalClusterSummaries), summarizing the discourse each cluster represents — useful for SEO-optimized content creation. Enabled by default; set generateTopicalSummaries: false to increase processing speed or if the summary request fails

6. generate_contextual_hint

   • Generate a topical overview of a text and provide insights for LLMs to generate better responses
   • Use it to get a high-level understanding of a text
   • Use it to augment prompts in your LLM workflows and AI assistants

7. generate_research_questions

   • Generate research questions that bridge content gaps from text, URL, or an existing InfraNodus graph
   • Use them as prompts in your LLM models and AI workflows
   • Use any AI model (included in InfraNodus API)
   • Content gaps are identified based on topical clustering

8. generate_research_ideas

   • Generate innovative research ideas based on content gaps identified in the text
   • Get actionable ideas to improve the text and develop the discourse
   • Use any AI model (included in InfraNodus API)
   • Ideas are generated from gaps between topical clusters

9. optimize_text_structure

   • Analyze the level of bias and coherence in text using knowledge graph analysis
   • If the text is too biased, develop the represented topics to balance the discourse
   • If the text is focused or diversified, develop the content gaps to deepen the analysis
   • If the text is dispersed, focus the most common gap topics to improve coherence
   • Choose response type: response, idea, question, or transcend

10. optimize_reasoning

    • Applies the same bias/coherence analysis to the model's own reasoning trace or chat with the user (pass it as text)
    • Detects whether the reasoning is biased, focused, diversified, or dispersed
    • Steers the reasoning toward optimal diversity and coherence at the same time
    • If too biased, develop the under-represented topics; if focused or diversified, bridge the content gaps; if dispersed, focus the most common gap topics
    • Returns a structural diagnosis (diversity stats, topical clusters, gaps) plus suggestions for how to continue thinking

11. generate_responses_from_graph

    • Generate responses based on an existing InfraNodus graph
    • Integrate them into your LLM workflows and AI assistants
    • Use any AI model (included in InfraNodus API)

    • Executes multiple analyses in sequence with progress tracking
    • Generates research ideas based on content gaps
    • Identifies latent topics and conceptual bridges to develop
    • Finds content gaps for deeper exploration

15. create_knowledge_graph

    • Create a knowledge graph in InfraNodus from text and provide a link to it
    • Use it to create a knowledge graph in InfraNodus from text
    • Also accepts statements (discrete items) with parallel categories and timestamps. Categories are stored as metadata on each statement (filter, group, delete, or relabel by them) and stay out of the graph unless categoriesAsNodes: true, which turns each label into a [[label]] node — meant for large knowledge bases and Obsidian vaults where the connections between pages are the point. The parent modes of wikilinksMode (obsidianStyle, parentAndConcepts) always make the parent page a node

16. generate_ontology_graph

    • Use AI to generate a reasoning ontology graph (entities and the relations between them) from one of three sources: a prompt (a topic — e.g. "build an ontology on AI attention mechanisms"), a text (a long document or a structural digest of a project, chunked server-side), or a sourceGraphName (an existing graph — e.g. a fully ingested repo or corpus — whose statements are read back, chunked, and condensed into an ontology)
    • ontologyMode: 'codebase' frames the extraction around modules, functions, data stores, services, and the concepts they implement; ontologyMode: 'procedural' writes a digest instead — prose statements on how the project works with [[wikilinks]], each typed as [principles], [rules], [procedures], [handoffs], [main_ideas] or [gaps] (saved as the statement's category), from an already-uploaded docs/structure graph; save it as repo-<project>-digest for optimize_knowledge_base; chunkSize (default 12000 chars) controls granularity; every chunk appends to the same graph and the response reports chunksProcessed / chunksTotal
    • 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-5 for richer ontologies (also claude-fable-5, gpt-5.6-terra); 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-5; 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

18. overlap_between_texts

    • Create knowledge graphs from two or more texts and find the overlap (similarities) between them
    • Use it to find similar topics and keywords across different texts

19. merged_graph_from_texts

    • Build a graph of all the texts and URLs provided, providing topical clusters and gaps present in the merged graph generated from all the texts
    • Use it to combine multiple sources into one graph and see clusters and content gaps across the merged content

20. difference_between_texts

    • Compare knowledge graphs from two or more texts and find what's not present in the first graph that's present in the others
    • Use it to find how one text can be enriched with the others

21. analyze_google_search_results

    • Generate a graph with keywords and topics for Google search results for a certain query
    • Use it to understand the current informational supply (what people find)

22. analyze_youtube_results

    • Generate a graph with keywords and topics from YouTube results for a query, channel, or playlist
    • Choose what to pull via searchMode: search (video metadata for a search term), comments (comments on a video), channel (a channel's videos — pass a username, URL, or @handle), playlist (a playlist's videos — pass a playlist ID or a URL with list=), subtitles / subtitlesChannel / subtitlesPlaylist (transcribed subtitles of a video / channel / playlist), or searchVideos (analyzes the content of the videos found — limit hard-capped to 20)
    • Control results with limit (default 100, max 2000), sortBy (Popular / Oldest / Latest), excludeDescriptions, importLanguage, and importRegion
    • Use it to understand the topics, clusters, and content gaps in the discourse around a video, channel, playlist, or search term on YouTube

23. analyze_related_search_queries

    • Generate a graph from the search queries suggested by Google for a certain query
    • Use it to understand the current informational demand (what people are looking for)

24. search_queries_vs_search_results

    • Generate a graph of keyword combinations and topics people tend to search for that do not readily appear in the search results for the same queries
    • Use it to understand what people search for but don't yet find

25. generate_seo_report

    • Analyze content for SEO optimization by comparing it with Google search results and search queries
    • Identify content gaps and opportunities for better search visibility
    • Get comprehensive analysis of what's in search results but not in your text
    • Discover what people search for but don't find in current results

26. memory_add_relations

    • Add relations to the InfraNodus memory from text
    • Automatically detect entities or use [[wikilinks]] syntax to mark them
    • Save memory to a specified graph name for future retrieval
    • Support automatic entity extraction or manual entity marking
    • Provide links to created memory graphs for easy access

27. memory_get_relations

    • Retrieve relations from InfraNodus memory for specific entities
    • Search for entity relations using [[wikilinks]] syntax
    • Query specific memory contexts or search across all memory graphs
    • Extract statements and relationships from stored knowledge graphs
    • Support both entity-specific searches and full context retrieval

28. retrieve_from_knowledge_base

    • Retrieve context from an existing InfraNodus knowledge graph using GraphRAG
    • Query your knowledge base with a natural language prompt to get relevant statements

    • Compatible with ChatGPT Deep Research mode via Developer Mode > Connectors

30. fetch

    • Fetch a specific search result for a graph
    • Can be used in ChatGPT Deep Research mode via Developer Mode > Connectors

31. enable_project_learnings

    • Create the opt-in, per-project, append-only learnings graph (learn-<project>) in your account — the place where the assistant saves what it learned about operating in a project
    • Called only when you explicitly ask to start saving learnings for a project; idempotent, so calling it again just returns the existing graph
    • The assistant tells you first what will be stored (project knowledge only, never anything about you), where (a private graph you can delete at any time), and that batches are shown before saving

32. add_project_learnings

    • Save learnings about a project — where things live, traps, conventions, decisions, workflows, and a self-assessment of what worked well and what should be done differently next time — as statements with a type category each, for later sessions on any client
    • Refuses (without error) when the project has not been enabled and never creates the graph itself
    • Dry run by default: returns what would be written, marking near-duplicates as reinforced; writes only with confirm: true — or in the same call when your client supports MCP elicitation and you approve the form
    • Rejects statements with secret-like content server-side (indices only, never the content)

33. get_project_learnings

    • Retrieve learnings for a project: by prompt (GraphRAG — most relevant statements plus an overview of what is known), by entity (a file path, module, or concept), or a structural overview with neither
    • Call with no project to list the projects that have learnings in your account
    • Returns enabled: false with an empty list when a project has no learnings graph — not an error

    Also available as the save-learnings prompt in clients that expose MCP prompts. Set INFRANODUS_LEARNINGS=0 to remove these three tools from the server entirely (see Project learnings).

34. optimize_knowledge_base

    • Structural feedback on a whole code base, document vault, or body of procedural knowledge (rules, frameworks, principles) from its digest graph (repo-<project>-digest / vault-<project>-digest) — or from a digest you write and pass as text, saved with saveAs
    • Diagnoses the structure (biased / focused / diversified / dispersed) and reads it for the chosen focus (codebase, vault, procedural, general): what dominates, which areas are under-developed (with latent-topic ideas), which clusters never connect — missing integrations, missing bridge notes, missing hand-offs between frameworks — plus AI suggestions for what to develop next
    • compareWith up to two other layers of the same project (e.g. digest vs structure map, docs vs code) and get what each has that the other lacks: rules without code, code without documentation, features described but not built
    • Two ways to get the digest: the assistant reads the project and writes it (the infranodus skill's digest build mode, or text + saveAs here), or generate_ontology_graph with ontologyMode: 'procedural' writes it server-side from an uploaded docs/structure graph
    • Pairs with the infranodus skill's build modes: full ingestion, digest, structure map, ontology

35. submit_workflow_feedback

    • Internal telemetry: after a workflow of InfraNodus calls, the assistant reports what it actually did with the output — how much it used, whether it contained anything new, whether it was the right tool, how many calls it took, concrete defects — as observations rather than a score; a rating is derived from them server-side
    • Autonomous: it never asks you anything and never surfaces in the conversation
    • The report contains short paraphrases of what you were working on (capped at 200 characters), the same policy as the prompts InfraNodus already logs; MCPCAT_ANONYMOUS=1 skips the per-user log entirely
    • Set INFRANODUS_FEEDBACK=0 to remove the tool (and the one-line nudge appended to workflow-ending results) from the server

36. delete_statements

    • Delete statements from a graph in your own account by a filter the server resolves — exactly one of categories (everything uploaded under a source label: a file path, a page name, a [[label]] parent), statements (exact text), query (substring or /regex/), before/after (ISO 8601 window), deleteAll (empties the graph but keeps its name, URL, and settings), or statementIds
    • Dry run by default: returns the matched count, a sample of the statements, and a per-category breakdown; nothing is removed until the same filter is sent again with confirm: true — or, on clients with MCP elicitation, until you accept the form in the same call. A filter that matches nothing returns deleted: 0 without asking
    • The per-source replace path: delete_statements with the source's category, then create_knowledge_graph to the same graph name. deleteAll then create_knowledge_graph rebuilds a graph in place
    • Irreversible, own-account only (no userName), never creates a graph, and the assistant is instructed never to call it on its own initiative. Set INFRANODUS_DELETE=0 to remove the tool from the server

37. update_statements

    • Edit statements of a graph in your own account in place — content, categories, or timestamp — keeping each statement's id, date, and position (unlike deleting and re-creating it)
    • Two modes: edits rewrites specific statements, each named by its exact current text (match, e.g. from analyze_existing_graph_by_name with includeStatements) or statementId; or one selector (the same as delete_statements, with all instead of deleteAll) plus set (addCategories, removeCategories, categories, timestamp) and/or replace ({ pattern, with }, substring or /regex/flags) for bulk relabelling or a find-and-replace across the graph — renaming a [[concept]] or a source path everywhere
    • Dry run by default: returns the matched count and the before → after of every change; nothing is written until the same arguments are sent again with confirm: true — or, on clients with MCP elicitation, until you accept the form in the same call. A request that matches nothing returns updated: 0 without asking
    • New content is capped at 1000 characters; for longer text use delete_statements then create_knowledge_graph. Irreversible (the old text survives only in the dry-run output), own-account only, never creates a graph, and the assistant is instructed never to call it on its own initiative. INFRANODUS_DELETE=0 removes it together with delete_statements

38. delete_graph

    • Delete one graph from your own account entirely — its statements, revisions, settings, and URL; the name becomes free again. delete_statements with deleteAll is the alternative that keeps the graph for a rebuild in place
    • Dry run by default: confirms the graph exists and reports its URL and whether it is a live graph; nothing is removed until the same graphName is sent again with confirm: true. Clients that support elicitation ask you directly and delete in the same call
    • Irreversible, own-account only (no userName; the graph is resolved from your API key's own graph list and the backend scopes the delete to the same user), and the assistant is instructed never to call it on its own initiative. INFRANODUS_DELETE=0 removes it together with the other two mutation tools

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)

0. 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)

0. Prerequisites

• Node.js 18+ installed
• InfraNodus API key (get yours at https://infranodus.com/api-access)

1. Clone and build the server:

   bash

   Copy

   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:

   Code

   Copy

   INFRANODUS_API_KEY=your-api-key-here
   

3. Inspect the MCP:

   Terminal

   Copy

   npm run inspect
   

Claude Desktop Configuration (macOS)

1. Open your Claude Desktop configuration file:

   bash

   Copy

   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:

   Code

   Copy

   %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?"
• "Identify the most influential concepts in this content"

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.

Usage Analytics & Privacy

To improve the product, this MCP server records which tools are used (tool names, errors, and latency). This helps us understand which features are useful and where things break. We do not train any models on your data — see the InfraNodus terms and conditions.

If you prefer these usage stats not to be linked to your InfraNodus account, set the MCPCAT_ANONYMOUS environment variable:

{
	"mcpServers": {
		"infranodus": {
			"command": "npx",
			"args": ["-y", "infranodus-mcp-server"],
			"env": {
				"INFRANODUS_API_KEY": "YOUR_INFRANODUS_API_KEY",
				"MCPCAT_ANONYMOUS": "1"
			}
		}
	}
}

With MCPCAT_ANONYMOUS=1 set, tool usage is still recorded but stays anonymous — it is not tied to your user account. It also disables the per-user submit_workflow_feedback log described under tool 34 (the report includes duration / error / retry of the call it rates).

Project learnings

The enable_project_learnings, add_project_learnings, and get_project_learnings tools let the assistant keep an append-only graph of what it learned about operating in a project (learn-<project> in your InfraNodus account). They are opt-in per project: the graph exists only after you explicitly ask to enable it, the write tool refuses when the graph is missing and never creates one, and every batch is shown to you before it is saved. If you never want these tools exposed, set INFRANODUS_LEARNINGS=0 in the server's environment (same place as MCPCAT_ANONYMOUS). To stop collecting for a project, delete its learn-<project> graph in InfraNodus.

As most tools have the doNotSave=1 option turned on, all the graphs you create are ephemeral and won't be saved into your InfraNodus account unless you explicitly ask the MCP server to do so. We will also not keep the logs of the data you process. We also never use your data for LLM training according to the InfraNodus [https://infranodus.com/terms-conditions](terms of service).
