Frequently asked questions
Can my AI automatically find the details for a specific payment by its ID?
Yes! Use the get_payment tool with the Payment ID. Your agent will respond with complete metadata, including amount, status, customer info, and transaction date in seconds.
How do I find my Payfunnels External API Key?
Log in to your Payfunnels dashboard, navigate to Billing > Integration, find the 'Payfunnels API Key' section, and click 'Generate' to see your unique secret key.
Can I process a partial refund via the AI?
The current refund_payment tool processes the full transaction amount. For partial refunds, we recommend using the main Payfunnels dashboard until support is added to the 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.
