How do I validate a user login token from my backend?

Use the `validate_login` tool with the user's `uid` and the `access_token` provided by the 4399 SDK. The agent will confirm if the session is legitimate and return the authentication code.

Can I check the status of a specific payment order?

Yes! Use the `query_order` tool with the 4399 order ID. Your agent will retrieve the transaction status, amount, and timestamp from the payment gateway.

Does it support high score submission?

Yes! The `submit_score` tool allows your agent to update the high score for a specific user ID on the configured 4399 leaderboard.

4399 Open Platform + VS Code Copilot FAQ

Common questions about integrating 4399 Open Platform MCP Server with VS Code Copilot.

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.
