Frequently asked questions
Can I cancel a booking directly from the chat?
Yes. Provide the Appointment ID to the 'cancel_calenso_appointment' tool, and the AI agent will remove it from your schedule.
How do I add a new customer profile?
Invoke the 'create_calenso_customer' tool with a JSON object containing the customer's details (like name and email).
Is it possible to query available staff members?
Yes, just use the 'list_calenso_staff' tool to pull the active roster of your bookable employees.
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.
