Can I see my team's vacation balances through my agent?

Yes. Use the `get_leave_balances` tool with a specific User ID. Your agent will retrieve the active leave balances representing vacation arrays globally, including different types of absences (e.g. Paid Leave, RTT) managed in Timmi.

How do I check the individual claims within an expense report?

The `list_expense_claims` tool allows your agent to extract absolute bounded individual claims for a specific Expense Report ID. You'll see precise dates, amounts, and native currency payloads for each item in the report.

Can my agent list all company departments defined in Lucca?

Absolutely. Use the `list_departments` tool to retrieve the strict hierarchical organizational units. Your agent will report the department names and their hierarchy, helping you understand the company's structural boundaries.

Lucca (HR & Finance Suite) + Claude Desktop FAQ

Common questions about integrating Lucca (HR & Finance Suite) MCP Server with Claude Desktop.

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.
