Frequently asked questions
Can I browse inboxes and read emails?
Yes. Browse public and private inboxes, read full email content including HTML, headers, and attachments.
How does Mailinator authentication work?
Mailinator uses a custom Token header for authentication against api.mailinator.com/api/v2.
Can I test SMS messages too?
Yes. Access SMS inboxes and read SMS messages for phone number-based testing.
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.
