Frequently asked questions
How do I find my everbill API Key?
In your everbill account, go to Settings (Einstellungen) > API / Interface (Schnittstelle) and generate your unique key.
Can I check specific product stock levels?
Yes! The list_products tool retrieves your complete inventory directory, including current stock counts and technical metadata.
How do I create a new invoice via AI?
Use the create_invoice tool by providing the customer_id and a JSON array of items (product IDs and quantities).
How does the OpenAI Agents SDK connect to MCP?
Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
Can I use multiple MCP servers in one agent?
Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.
Does the SDK support streaming responses?
Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
