Frequently asked questions
How do I get my MightyCall API credentials?
Log in to your MightyCall dashboard, navigate to the API or Integrations section, and generate your Client ID and Client Secret.
Can I make outgoing calls?
Yes, use the make_call tool and specify which of your business numbers to use as the source and the target destination number.
Does it track voicemail status?
Absolutely. The list_voicemails tool retrieves your recent messages along with their duration and current status (read/unread).
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.
