GitHub Copilot (IDE)

Add Trunk’s MCP Server to GitHub Copilot

One-click setup

Use the “Add to VS Code” action to add the Trunk MCP server

Command Palette setup

Run CMD+Shift+P to open the Command Palette and choose MCP: Add Server. Choose HTTP and input https://mcp.trunk.io/mcp. Set the name to trunk.

A new window will open to confirm the MCP configuration. It should show:

{
	"servers": {
		"trunk": {
			"url": "https://mcp.trunk.io/mcp",
			"type": "http"
		}
	},
	"inputs": []
}

Alternative: Update MCP configuration

Add the following configuration to your project’s .vscode/mcp.json file.

{
  "mcpServers": {
    "trunk": {
      "url": "https://mcp.trunk.io/mcp",
      "type": "http"
    }
  }
}

Authentication with OAuth (default)

After the MCP server was added, users need to authorize GitHub Copilot to communicate with the server. Follow these steps to complete auth.

Step 1: Start MCP server

Run CMD+Shift+P to open the Command Palette and choose MCP: List Servers. Choose trunk and select Start Server to authenticate.

Step 2: Login & authorize

A new webpage will be opened. Login with your Trunk account and follow instructions to authorize GitHub Copilot to communicate with the MCP server.

Step 3: Confirm

Follow instructions to get back to GitHub Copilot. With auth completed, GitHub Copilot will be able to fetch the tools exposed by Trunk’s MCP server.

Alternative: Authentication with API token

If you prefer not to use the OAuth flow, you can authenticate with your Trunk organization API token. Find your token under Settings > API in the Trunk dashboard.

Add the token to your .vscode/mcp.json:

{
  "mcpServers": {
    "trunk": {
      "url": "https://mcp.trunk.io/mcp",
      "type": "http",
      "headers": {
        "Authorization": "Bearer ${env:TRUNK_API_TOKEN}"
      }
    }
  }
}

VS Code uses ${env:VARIABLE_NAME} syntax for environment variable interpolation in MCP configuration files, unlike other clients which use ${VARIABLE_NAME}.
