Stop Claude Desktop from hallucinating correlation as causation

The `validate_causal` tool forces your Claude Desktop app to build a directed acyclic graph of your variables before it writes a single line of analysis. It stops the LLM from making lazy leaps based on statistical proximity. By mapping out nodes and drawing explicit directed edges, your local Claude client stops treating word co-occurrence as a physical cause-and-effect link. We run this causal validation check right in your local Claude Desktop setup using your config file. When your agent attempts to infer why a metric dropped, the MCP server rejects any conclusion that relies on mere association, forcing a strict traversal of the causal graph instead.

Debug cyclic feedback loops inside your local chat

The `validate_causal` tool scans your network of variables for cyclic loops and logical contradictions directly inside Claude Desktop. If your agent tries to argue that system load causes database latency while database latency simultaneously causes system load, the tool flags the circular logic immediately. This local MCP interface runs these validations as subprocesses on your machine. You get immediate feedback in your sidebar whenever Claude Desktop tries to feed you circular reasoning during system architecture reviews.

Enforce DAG validation during local root-cause analysis

The `validate_causal` tool turns Claude Desktop into a strict logic engine by demanding a fully validated directed acyclic graph for every conclusion. The tool isolates statistical associations from direct physical causation, blocking the agent from jumping to easy, wrong conclusions. You configure this behavior via your local config file. Once active, the server ensures that every diagnostic path your local agent proposes is derived strictly by traversing the mapped nodes.

Setup guide

Set up Causal-Graph Navigator MCP in Claude Web or Desktop

1

Open Claude Settings

Go to claude.ai, click your profile icon, then navigate to Customize → Connectors.
2

Add Custom Connector

Click the "+" button and select Add custom connector. Paste your Vinkius endpoint URL: https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. For OAuth-protected servers, expand Advanced settings to add credentials.
3

Start a conversation

Open a new chat. The Causal-Graph Navigator MCP tools are available immediately — no restart needed.

Endpoint URL

https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp

No configuration file needed — paste the URL directly in the Claude web interface.

Available on Free (1 connector), Pro, Max, Team, and Enterprise plans.

Prerequisites

Claude Desktop installed (macOS or Windows)
Active Vinkius subscription with a valid endpoint token

1

Open Claude Desktop Settings

Click the menu icon at the top-left corner, go to Settings → Developer → Edit Config. This opens claude_desktop_config.json in your default text editor.
2

Paste the Causal-Graph Navigator MCP configuration

Copy the JSON snippet on the right into the mcpServers object. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Restart Claude Desktop

Close and reopen the application. Claude needs a full restart to load new MCPs — refreshing a conversation is not enough.
4

Verify the connection

Open a new conversation. Click the 🔌 icon at the bottom of the message input. You should see tools listed under causal-graph-navigator-mcp.

Common questions about Causal-Graph Navigator MCP in Claude Desktop

It intercepts Claude Desktop queries and routes them through the `validate_causal` tool. This forces the LLM to map variables as explicit nodes and draw directed edges rather than guessing based on word proximity.

Yes, you can load Causal-Graph Navigator directly via your local JSON configuration. The tool then forces your desktop agent to validate all system dependencies and eliminate circular reasoning before suggesting changes.

It runs as a local subprocess managed by your Claude Desktop application. The `validate_causal` tool executes locally on your machine, ensuring no external API calls are made to parse your causal graphs.

The tool rejects the agent's logic and returns a validation error. This forces your agent to rewrite its reasoning using actual graph traversal instead of lazy word association.

Your causal node networks and variable maps never leave your local machine during validation. The server processes all node data in a secure, local sandbox, meaning your raw system telemetry and dependency text remain entirely private.
