How to Use the Engineering Reasoning Prover MCP in Cursor

Q: How do I set up Engineering Reasoning Prover in Cursor for my project?

Create a .cursor/mcp.json file in your project's root directory. Add the server configuration there, and it will be active for anyone who opens that project in Cursor.

Inject standards-compliant analysis and code directly into your project with Cursor.

Generate Code That's Already Compliant

The `validate_engineering_reasoning` tool forces your agent to think before it codes. When you ask for a function that models a physical system, the agent first has to prove its understanding of the underlying engineering principles to the Prover. The result? The code Cursor generates for you is based on a validated argument. It's not just code that runs, it's code that reflects a correct, standards-based interpretation of the problem.

Turn Analysis into Actionable Code

Don't just chat about compliance, write the code for it. Use the `validate_engineering_reasoning` tool to confirm your approach for a stress calculation. Once validated, tell your agent to write the Python function that implements that exact calculation. This closes the gap between analysis and implementation. The validated parameters, formulas, and acceptance criteria from the tool's output become the constants, functions, and unit tests in your editor, right where you need them.

Validate Engineering Decisions in Your IDE

Settle a design debate with data. While editing a file in Cursor, you can ask your agent to evaluate a technical choice. The agent uses `validate_engineering_reasoning` to frame the argument, forcing a check against standards and a quantification of risks. The output appears directly in your chat panel. You get a structured, unbiased verdict on the engineering trade-off without ever leaving your code. It's like having a senior principal engineer on call, but one that demands you show your work.

Setup guide

Set up Engineering Reasoning 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 Engineering Reasoning 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 Engineering Reasoning Prover transactions." If the MCP tools are loaded correctly, Cursor will call the Engineering Reasoning Prover tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

  "mcpServers": {
    "engineering-reasoning-prover-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"

Common questions about Engineering Reasoning Prover MCP in Cursor

Create a `.cursor/mcp.json` file in your project's root directory. Add the server configuration there, and it will be active for anyone who opens that project in Cursor.

Yes, indirectly. After validating an engineering calculation with the tool, you can instruct your agent to write unit tests using the exact inputs, outputs, and acceptance criteria from the validated proof.

No, it makes peer review better. It forces the initial analysis to be so rigorous and well-documented that your team can focus on core assumptions, not on chasing down missing citations or basic math errors.

The tool will return an error explaining what's missing—a standard citation, a risk calculation, and so on. Your agent then has to correct its analysis and try again. You see this whole process in the chat, so you know why the final answer is solid.

The server only ever sees the specific engineering arguments your agent sends for validation to the tool. It has no access to your source code or files. Each request is handled in a dedicated, memory-safe sandbox on Vinkius and wiped clean immediately after.
