Frequently asked questions
Can I search for items specifically in a format like 'maps' or 'audio'?
Yes! Use the search_format tool and specify the format parameter (e.g., 'maps', 'photos', 'audio') along with your query to get targeted results.
How do I get the full OCR text of a digitized document?
You can use the get_text_service tool. Provide the document segment path and set the full_text parameter to 1 to retrieve the complete OCR transcript.
Can I list items from a specific collection like the Abraham Lincoln papers?
Yes. Use the get_collection_items tool with the collection slug (e.g., 'abraham-lincoln-papers') to see all items contained within that specific archive.
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.
