FAQ

Frequently asked questions

Can I calculate sales tax for a specific address via AI?

Yes! Use the calculate_sales_tax tool. Provide the destination country, zip code, and state along with the order amount. Your agent will return the precise tax to be collected.

How do I see in which states I have a tax nexus?

Run the list_nexus_regions query. The agent will retrieve a list of all regions (states or countries) where you have configured a tax nexus in your TaxJar account.

Is it possible to validate a shipping address via AI?

Absolutely. Use the validate_tax_address tool and provide the full address details. The agent will verify the address through TaxJar to ensure it is accurate for tax purposes.

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.
