How to Use the Aristotle Logic Prover MCP in Cursor

Q: How do I add Aristotle Logic Prover to my Cursor workspace?

Create an .cursor/mcp.json file in your project root and add the MCP server details under the mcpServers key. Once configured, enable Agent mode in your Cursor chat to let the editor invoke the logic verification tools.

Run the Aristotle Logic Prover inside Cursor to validate architectural definitions and syllogisms as you write code.

Define code entities precisely in Cursor

The `validate_aristotle_logic` tool targets semantic ambiguity in your codebase by forcing strict genus-differentia definitions. When you prompt Cursor in Agent mode to generate a new class or module, this MCP server inspects the conceptual framework. It prevents your agent from writing code based on sloppy terms that lack clear boundaries. By integrating this check directly into your editor, you catch category errors before they turn into buggy interfaces. Your agent must explicitly state what a class is (its genus) and what makes it unique (its differentia).

Verify logic flows using this MCP Server

The `validate_aristotle_logic` tool tests your code's underlying logic through formal categorical syllogisms. Instead of relying on hope, Cursor uses this tool to check if your conditional branches and business rules actually follow from your stated premises. Running this validation via an MCP server ensures your agent generates code built on sound reasoning. The tool flags logical leaps and invalid inferences directly in your active file, keeping your execution paths clean.

Map code purpose with the four causes

The `validate_aristotle_logic` tool analyzes your software design using Aristotle's four causes: material, formal, efficient, and final. It forces your agent to document not just how a function executes, but exactly what the function is for. This prevents purpose blindness in complex codebases. When Cursor writes code with this context, the resulting documentation clarifies the architectural intent of every module, reducing future refactoring friction.

Setup guide

Set up Aristotle Logic Prover MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the Aristotle Logic Prover MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent Aristotle Logic Prover transactions." If the MCP tools are loaded correctly, Cursor will call the Aristotle Logic Prover tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "aristotle-logic-prover-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
  }

Common questions about Aristotle Logic Prover MCP in Cursor

Create an `.cursor/mcp.json` file in your project root and add the MCP server details under the mcpServers key. Once configured, enable Agent mode in your Cursor chat to let the editor invoke the logic verification tools.

No, the validation runs in under three seconds. The tool is designed for rapid execution, giving your agent instant feedback without interrupting your coding flow.

Yes, by using the logic verification tool, you establish clear syllogisms for how your code must behave. Cursor can then translate those proven logical conclusions directly into concrete test assertions.

The tool requires you to define terms using formal genus and differentia. If your agent describes a class with accidental properties instead of essential ones, the prover flags a category error and halts.

The server processes your code structures, class definitions, and syllogistic assertions inside a secure, ephemeral sandbox. Your proprietary source code and architectural metadata are never stored or used for model training.
