Connect Counterfactual-Variant Prover MCP to VS Code Copilot

Enforce strict logic in VS Code Copilot
This MCP Server ensures your team avoids common logic errors when testing modified constraints. The `validate_counterfactual` tool forces the agent to isolate your variables immediately. Instead of guessing, the agent must map your rules against the standard version. It catches when the model tries to cheat with memorized answers.
Audit puzzle reasoning in VS Code Copilot
You can now trace the agent's calculations from first principles. The tool requires a step-by-step breakdown of how the final answer was reached. This is essential for team projects where logic accuracy matters. You get a clear, decontaminated output that matches your specific puzzle rules.
Prevent template bias in VS Code Copilot
The server checks for contamination in the agent's logic. If it detects a fallback to a classic puzzle solution, it flags the error. This forces the agent to discard the template and re-evaluate the problem. You get reliable, accurate results every time.
