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.
How does Claude Desktop discover MCP tools?
When Claude Desktop starts, it reads the claude_desktop_config.json file and connects to each configured MCP server. It calls the tools/list endpoint to fetch the schema for every available tool, then surfaces them as clickable options in the chat interface via the 🔌 icon.
What happens if the MCP server is temporarily unavailable?
Claude Desktop handles disconnections gracefully. if the server is unreachable at startup, the tools simply won't appear. Once the server becomes available again, restarting Claude Desktop will re-establish the connection. There is no timeout penalty or error loop.
Can I connect multiple MCP servers simultaneously?
Yes. You can add as many servers as you need in the mcpServers section of the config file. Each server appears as a separate tool provider, and Claude can use tools from multiple servers in a single conversation turn.
Is there a limit on the number of tools per server?
Claude Desktop can handle hundreds of tools per server. However, for optimal LLM performance, Vinkius servers are designed to expose focused, well-documented tool sets rather than overwhelming the model with too many options.
Does Claude Desktop support Streamable HTTP transport?
Yes. Claude Desktop supports both SSE (Server-Sent Events) and the newer Streamable HTTP transport that Vinkius uses. Simply provide the server URL. Claude auto-negotiates the transport protocol.
Server not appearing after restart
Ensure the JSON is valid (no trailing commas). Check the file path: ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\\Claude\\ (Windows).
Authentication error

Tools not showing in chat
