Team-wide API mocking in VS Code Copilot

Commit your .vscode/mcp.json file to your repository so every developer on your team uses the same mock data tools. It ensures everyone is testing against the same base. Use `list_todos` or `list_albums` to keep your team's local environments consistent.

Drive development with real API responses

Stop guessing what your API returns. Use `get_post` and `get_user` to pull the exact JSON structure into your chat. Your code generation becomes more accurate when the agent works with actual API signatures.

Manage state changes in VS Code Copilot

Test your frontend's handling of updates by using `patch_post` or `create_post`. It gives you a quick way to verify that your forms and state handlers work as expected. These tools make it trivial to simulate a backend without writing a single line of server code.

Setup guide

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

.vscode/mcp.json

  "mcpServers": {
    "jsonplaceholder-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
  }
