FAQ

Frequently asked questions

01

Can I check the stock level of an item via AI?

Yes! Use the get_item_details tool and provide the Item ID. Your agent will retrieve the complete metadata, including current stock levels for that product.

02

How do I create a new invoice for a client?

Use the create_invoice action. You'll need to provide the Contact ID, date, due date, and a JSON string of items to register the new sale in Alegra.

03

Is it possible to list all my recent payments?

Absolutely. Use the list_payments query. The agent will retrieve a list of all recorded income payments received in your account.

04

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.

05

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.

06

Does the SDK support streaming responses?

Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
