Team Decision Logic via MCP Server

The `get_decision` tool lets your entire engineering team access random yes/no/maybe decisions through the shared .vscode/mcp.json config. It's ideal for standardizing agent logic across projects. This ensures every developer uses the same simple mechanism when simulating unpredictable inputs.

Testing Edge Cases with Copilot Chat

You can invoke `get_decision` directly in Copilot Chat’s Agent mode. The tool gives a random yes/no/maybe result, complete with a GIF, which is excellent for testing how the team's code handles unpredictable inputs. It keeps your logic robust without requiring complex test data setups.

Implementing Simple Randomization

The `get_decision` tool delivers an instant random yes/no/maybe choice. For team members who need to include a simple, chance-based decision point in the codebase, this is a straightforward integration. It's low friction and easy for all developers to adopt via shared configuration.

Setup guide

Set up YesNo 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 YesNo 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 YesNo tools listed. Try asking: "List my recent YesNo transactions" and Copilot will invoke them automatically.
