Frequently asked questions
How do I find my ShangQian Developer ID and Secret?
Log in to the BestSign Developer Platform, navigate to the 'Application Management' or 'Credentials' section to find your unique Developer ID and RT Secret.
What is the 'account' identifier?
The account identifier is a unique string used to identify a user in the ShangQian system, typically a mobile phone number or an email address. It is required for registration and signing operations.
Does this server handle HMAC-SHA1 signatures?
Yes! The server automatically calculates the required HMAC-SHA1 signature using your RT Secret for every request, ensuring secure authorized communication with the ShangQian API.
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.
Tools not appearing in Cursor
Ensure you are in Agent mode (not Ask mode). MCP tools only work in Agent mode.
Server shows as disconnected
Check Settings → Features → MCP and verify the server status. Try clicking the refresh button.
