FAQ

Frequently asked questions

01

Can my AI initiate phone calls?

Yes. Use create_call with an agent ID and phone number. The AI agent handles the conversation automatically.

02

Can I read call transcripts?

Yes. get_call_transcript returns the full conversation for any completed call.

03

How do I create a new voice agent?

Use create_agent with a name and system prompt. The agent will use the prompt to guide conversations.

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.
