Can I see the signed PDF of an invoice through my agent?

Yes. Use the `get_invoice` tool with a specific Invoice ID. Your agent will return all document details along with a permalink to the signed PDF, allowing you to view or share the official fiscal document instantly.

How do I find a client by their company name?

The `find_client` tool allows you to search for a client directly by their business name. This is perfect for locating a client profile when you don't have their numerical ID handy.

Can I list the VAT rates available in my account?

Absolutely. Use the `list_taxes` tool to enumerate all VAT rates and exemptions configured in your InvoiceXpress account. Your agent will show the official AT mapping, which is essential before creating new items or invoices.

InvoiceXpress (Online Invoicing) + Cursor FAQ

Common questions about integrating InvoiceXpress (Online Invoicing) 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.
