Frequently asked questions
Can I send SMS to multiple recipients at once?
Yes! Use send_bulk_sms with a comma-separated list of phone numbers in international format. All recipients receive the same message.
How do I check if my message was delivered?
Use get_delivery_report with the transmission ID returned when the SMS was sent. It shows real-time delivery status (delivered, pending, failed).
Can I schedule messages for later?
Yes! Use schedule_sms with the delivery date in ISO 8601 format (e.g., 2025-01-15T14:00:00Z). The message will be sent at the specified time.
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.
