Can I bulk cancel tax invoices directly on the Mexican IRS bypassing visual interfaces?

Yes. Utilize the `cancel_invoice` target tool carefully giving it the unique CFDI ID alongside the formal SAT motive parameter representing your reasoning, and it actively invalidates the fiscal stamp instantly at source.

How securely does the Basic Authentication hold within Vurb handling the Mexican invoices?

The variables act as deep protected MCP credentials. You input them once securely mapping directly to fields labeled with generic `sensitive: true`. They transform cleanly into masked Base64 encodings locally and disappear off visual UI radar guaranteeing no accidental token logging into public clouds.

Can I retrieve a raw representation like PDF base64 of an older CFDI directly via Claude text generation?

Absolutely. Deploy `get_invoice_file` referencing the exact entity ID while choosing between XML or PDF format outputs, granting heavy duty tracking across any calendar timeline seamlessly.

Facturama (SAT) + Claude Desktop FAQ

Common questions about integrating Facturama (SAT) 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.
