VS Code

VS Code’s GitHub Copilot Chat (in Agent mode) supports MCP servers via workspace or user mcp.json files.

Prerequisites

• Visual Studio Code 1.94 or newer.
• GitHub Copilot Chat extension installed and signed in.
• An Estaite MCP API key from estaite.com/developers.

Config file location

Scope	Path
User	Run the MCP: Open User Configuration command from the palette
Workspace	.vscode/mcp.json in your repo root

Config

{
  "servers": {
    "estaite": {
      "type": "http",
      "url": "https://mcp.estaite.com",
      "headers": {
        "x-api-key": "YOUR_API_KEY"
      }
    }
  }
}

Replace YOUR_API_KEY with your key. To avoid checking the key into source control, use VS Code’s input-variable syntax:

{
  "inputs": [
    {
      "id": "estaite-key",
      "type": "promptString",
      "description": "Estaite MCP API key",
      "password": true
    }
  ],
  "servers": {
    "estaite": {
      "type": "http",
      "url": "https://mcp.estaite.com",
      "headers": {
        "x-api-key": "${input:estaite-key}"
      }
    }
  }
}

VS Code will prompt for the key the first time the server is started and cache it for the workspace.

Apply

Open the Copilot Chat view, switch to Agent mode, and select the estaite server from the tool picker. The 13 tools appear under that server’s name.

Troubleshooting

• Server not listed — confirm Copilot Chat is in Agent mode (the mode selector at the bottom of the chat view). MCP tools only show in Agent mode.
• 401 — the key in headers["x-api-key"] is wrong, blank, or revoked.
