Frequently asked questions
Can I create and send invoices?
Yes. Create draft invoices with contact ID and line items, then send them directly to the customer via the API.
How does Moneybird authentication work?
Moneybird requires a Bearer API Key and an Administration ID against moneybird.com/api/v2/{administrationId}/.
Can I list bank transactions?
Yes. Financial mutations (bank transactions) can be listed for reconciliation purposes.
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.
