Team-wide logic guardrails via MCP Server

The `validate_critical_thinking` tool establishes a shared standard for how your team's AI agent solves complex architectural problems. By committing the configuration to your repository, every developer gets automated reasoning checks. The agent must analyze problems from multiple angles using named mental models. It cannot push biased or single-perspective solutions to your shared codebase.

Empirical verification of every pull request

The `validate_task_completion` tool ensures that Copilot does not declare a task finished without proof. Every modified file path must be explicitly mapped alongside real test execution logs. Any attempt to bypass requirements or submit incomplete code results in a hard tool rejection. This keeps your main branch clean and reduces manual code review overhead.

Zero-trust execution for enterprise development

Running this MCP server through the Vinkius infrastructure ensures your development workflows stay secure. The server operates in an ephemeral environment using a single secure endpoint token. Your developers get immediate access to advanced reasoning capabilities without managing complex local runtimes. It fits cleanly into your existing VS Code workspace setup.

Setup guide

Set up Critical Thinking Prover MCP in VS Code Copilot

Prerequisites

VS Code 1.99 or later with GitHub Copilot extension
Active Vinkius subscription with a valid endpoint token

1

Open MCP configuration

Open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and run "MCP: Add Server". Select HTTP (Streamable) as the server type. VS Code will create .vscode/mcp.json in your workspace.
2

Add the Critical Thinking Prover MCP

Paste the JSON snippet shown on the right into your .vscode/mcp.json. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Switch to Agent mode

Open Copilot Chat (Cmd+Shift+I / Ctrl+Shift+I) and switch to Agent mode using the dropdown. MCP tools are only available in Agent mode — they do not appear in Edit or Ask modes.
4

Verify the connection

In the Copilot Chat input, type # to list available tools. You should see the Critical Thinking Prover tools listed. Try asking: "List my recent Critical Thinking Prover transactions" and Copilot will invoke them automatically.

Common questions about Critical Thinking Prover MCP in VS Code Copilot

You save the server settings in your workspace configuration file and commit it to Git. Anyone opening the repository with VS Code 1.96 or higher will automatically use the workspace configuration for the MCP server.

It blocks the agent from declaring a task complete if the reasoning is flawed or logs are missing. The `validate_task_completion` tool rejects the action, forcing Copilot to fix the code.

The `validate_critical_thinking` tool requires the agent to apply named mental models to the problem. It stops Copilot from defaulting to the easiest, most biased approach.

The rules are baked into the server tools to maintain a high bar of logical rigor. This keeps the validation consistent across different projects and developers.

All validation data is handled within isolated, zero-trust environments. Vinkius runs the MCP server in an isolated sandbox, ensuring your file structures, test outputs, and logical arguments are never stored or used for training.
