Frequently asked questions
Can I identify which companies are visiting my website?
Yes! The list_visitors tool retrieves all identified B2B website visitors with company name, industry, employee count, and visit details. Use search_visitors to find specific companies by name or domain, and list_visitors_by_country to filter by geographic region. Use get_visitor for the full company profile.
Can I see which pages each company visited and how long they stayed?
Yes. Use list_sessions with a Visitor ID to see all browsing sessions, then get_session for page-by-page navigation paths with time spent per page. Use list_page_views to get all pages viewed by a specific visitor. This reveals purchase intent — visitors spending time on pricing or demo pages are warm leads.
Can I focus only on high-intent qualified leads?
Yes. The list_qualified_leads tool retrieves only leads that meet your qualification criteria (e.g., multiple visits, pricing page views, minimum session duration). Use list_leads_by_industry to further filter by vertical. Use list_notifications for real-time alerts when high-value visitors are on your site.
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.
