Can I check if an invoice has been paid through the agent?

Yes. The `list_accounting_invoices` tool allows your AI agent to see the current status of all invoices, including whether they are 'PAID', 'SAVED' (unpaid), or still in 'DRAFT' status.

How do I add a new client to my Wave account using chat?

You can use the `create_accounting_customer` tool. Just provide the customer's name and email address, and your agent will register them in your Wave business instantly.

Can I delete a draft invoice if I made a mistake?

Yes. The `delete_draft_invoice` tool allows you to permanently remove unfinalized draft invoices. Note that once an invoice is approved (SAVED) or paid, it cannot be deleted through this specific tool.

Wave Accounting + Claude Desktop FAQ

Common questions about integrating Wave Accounting 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.
