VS Code Copilot: Team Safety Gate

The `validate_yakunashi` tool provides a consistent, organization-wide safety net for all developers via the committed `.vscode/mcp.json`. It forces the AI to list every required precondition before suggesting code changes or implementing features. This means that whether you're working on client A or client B, the team standard is always adherence to verifiable facts.

MCP Server: Preventing Hallucinated Logic

When Copilot Chat uses this MCP Server, it detects 'speculation,' stopping any attempt to write code based on assumed data. If a function needs the weather briefing (METAR/TAF) to run correctly, and that data isn't in the repo context, the tool flags it. It ensures team-wide quality control by demanding documented evidence for every line of logic.

VS Code Copilot: Calibrating Confidence on Commit

The `validate_yakunashi` mechanism helps the team calibrate confidence levels before a commit. Instead of accepting an 'N/A' answer, it forces the AI to state its certainty based only on what’s in the codebase or provided context. This prevents developers from approving designs that are only partially supported by existing documentation.

Setup guide

Set up Yakunashi-Safety Gate 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 Yakunashi-Safety Gate 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 Yakunashi-Safety Gate tools listed. Try asking: "List my recent Yakunashi-Safety Gate transactions" and Copilot will invoke them automatically.

Common questions about Yakunashi-Safety Gate MCP in VS Code Copilot

It mandates the mapping of all necessary preconditions. For any data-dependent question, it requires listing every single fact that must be true for the code to function correctly. You can't guess your way through a build.

Yes. The tool detects when the agent is generating information instead of retrieving it from the local context, triggering safe folding and preventing the commit of fabricated data.

This MCP Server validates factual parameters used in engineering and development—things like soil type, bearing capacity, or circuit breaker details. It ensures the code relies on documented reality.

Absolutely. By committing the configuration to `.vscode/mcp.json`, it becomes a standard, predictable part of your team's CI/CD process, improving consistency.

It triggers 'safe folding.' The developer sees an immediate, clear message stating exactly what information—for example, the load calculations—is missing and why that gap will lead to system failure.
