Frequently asked questions
How do I get my Vibrato API Key?
Log in to your account at getvibrato.com, navigate to the API Keys section, and copy your unique secret key.
Does it provide call recordings?
Yes, you can access call recordings and live transcripts through the get_call_status tool once a call is in progress or completed.
Can I use custom prompts?
Absolutely. The create_call tool allows you to provide a custom natural language prompt to define exactly what the AI should achieve during the call.
How does AutoGen connect to MCP servers?
Create an MCP tool adapter and assign it to one or more agents in the group chat. AutoGen agents can then call Vibrato tools during their conversation turns.
Can different agents have different MCP tool access?
Yes. AutoGen's role-based architecture lets you assign specific MCP tools to specific agents, so a querying agent has different capabilities than a reviewing agent.
Does AutoGen support human approval for tool calls?
Yes. Configure human-in-the-loop mode so agents pause and request approval before executing sensitive MCP tool calls.
