Frequently asked questions
Can the AI perform destructive actions like making a real payment or deleting invoices?
No. The integration focuses strongly on extraction via READ endpoints (e.g. list_payments, list_budgets, list_expense_claims). It is designed to act as an advanced analytical viewing lens allowing you to query, organize, and monitor financial positions without executing operational mutations like transferring money.
How can the AI help me understand a specific expense claim?
You can provide the Expense ID from your list_expense_claims search and ask natural questions. The AI will pull the structured data and explain explicitly who submitted the reimbursement, the exact amount, the associated spending currency, and the current processing status, formatting it all into an easily digestible summary.
How deep is the Spendesk token scoped? Is it secure?
The integration is secure. Your Vinkius Agent runs strictly client-side on your PC. It queries the API using the explicit Bearer Token you manage. Spendesk's token access capabilities can also be carefully constrained natively from your Organization's Integration Settings to further enforce least privilege.
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
Verify your Vinkius token is correct. Go to cloud.vinkius.com to regenerate it if needed.
Tools not showing in chat
Click the 🔌 icon at the bottom of the chat input. If it shows 0 tools, the server may still be connecting. wait a few seconds.
