Frequently asked questions
Can I verify if a physical address is valid via AI?
Yes! Use the validate_physical_address tool and provide the address string. Your agent will return the structured, autocompleted data and verification status.
How do I check if an email address is active using the agent?
Use the validate_email tool. Provide the address, and Foxentry will check for syntax, domain validity, and if the specific mailbox actually exists.
Is it possible to retrieve business data using a registration number via AI?
Absolutely. Use the lookup_business_data query and provide the registration number. The agent will retrieve official company names and registered addresses.
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.
