Frequently asked questions
Can I send SPEI transfers to any Mexican bank from my AI agent?
Yes! Use the create_transfer tool with the recipient's 18-digit CLABE number, the amount in MXN, and an optional concept description. Transfers are processed instantly during banking hours through Mexico's SPEI interbank system.
Can I see which purchases were made with meses sin intereses?
Yes. Use list_credit_card_transactions to see all your credit card charges. Each transaction includes its installment details — whether it was a single payment or spread across 3, 6, 12, or 18 months interest-free (meses sin intereses), along with the remaining installments.
How does the spending analytics feature work?
Use get_spending_analytics with a period (last_month, last_3_months, last_year). It returns your spending broken down by category (food, transport, entertainment, etc.), your top merchants, and comparison percentages against your previous period.
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.
