Frequently asked questions
What format is required for the instance host?
Provide the full hostname without the 'https://' prefix, for example: box.yourdomain.com.
Can I add multiple forwarding targets to an alias?
Yes, when using the create_or_update_alias tool, provide a comma-separated list of emails in the forwards_to field.
Does this work with 2FA enabled accounts?
The current API implementation uses Basic Auth. If 2FA is enabled on your admin account, you may need to use an API key or a dedicated admin user without 2FA for the integration.
Which VS Code version supports MCP?
MCP support requires VS Code 1.99 or later with the GitHub Copilot extension. Ensure both are updated to the latest version. Older versions of Copilot may not expose the Agent mode toggle.
How do I switch to Agent mode?
Open the Copilot Chat panel and look for two mode options: "Ask" and "Agent". Click "Agent" to enable autonomous tool calling. In Ask mode, Copilot provides conversational answers but cannot invoke MCP tools.
Can I restrict which MCP tools Copilot can access?
Yes. VS Code shows a tool consent dialog before any MCP tool is invoked for the first time. You can also configure tool access policies at the organization level through GitHub Copilot settings.
Does MCP work in VS Code Remote or Codespaces?
Yes. MCP servers configured via .vscode/mcp.json work in Remote SSH, WSL, and GitHub Codespaces environments. The MCP connection is established from the remote host, so ensure the server URL is accessible from that environment.
MCP tools not available
Ensure you are in Agent mode in Copilot Chat. MCP tools only appear in Agent mode.
