Connecting VS Code (Copilot)

GitHub Copilot in VS Code can use MCP tools in agent mode.

Steps

1. Create the file .vscode/mcp.json in your project:

{
  "inputs": [
    { "type": "promptString", "id": "eenfactuurmaken-api-key", "description": "EenFactuurMaken.nl API key", "password": true }
  ],
  "servers": {
    "eenfactuurmaken": {
      "type": "http",
      "url": "https://eenfactuurmaken.nl/mcp",
      "headers": { "Authorization": "Bearer ${input:eenfactuurmaken-api-key}" }
    }
  }
}

2. Click Start above the server. The first time, VS Code asks for your API key and stores it securely. So the key isn't in the file.
3. Open Copilot Chat, choose Agent and click the tools icon to check that the EenFactuurMaken.nl tools are on.
4. Ask, for example: "Which invoices are overdue?"

Want the server in all your projects? Add it with the MCP: Add Server command and choose your user settings.

You create an API key under Settings → API & AI. See API keys and apps.
