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 + Cursor FAQ

Common questions about integrating 4399 Open Platform MCP Server with Cursor.

What is Agent mode and why does it matter for MCP?

Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.

Where does Cursor store MCP configuration?

Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.

Can Cursor use MCP tools in inline edits?

No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.

How do I verify MCP tools are loaded?

Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
