Frequently asked questions
Can I verify if a physical address is valid via AI?
Yes! Use the validate_physical_address tool and provide the address string. Your agent will return the structured, autocompleted data and verification status.
How do I check if an email address is active using the agent?
Use the validate_email tool. Provide the address, and Foxentry will check for syntax, domain validity, and if the specific mailbox actually exists.
Is it possible to retrieve business data using a registration number via AI?
Absolutely. Use the lookup_business_data query and provide the registration number. The agent will retrieve official company names and registered addresses.
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.
