Frequently asked questions
How can I find the estimated rental income for a specific property?
You can use the get_rental_avm_long_term tool for traditional rentals or get_rental_avm_short_term for vacation rentals. Simply provide the property address to get an automated valuation (AVM).
Can I search for properties within a specific geographic area?
Yes! Tools like get_property_records and get_sale_listings support searching by city, state, zip code, or even circular searches using latitude, longitude, and radius parameters.
Does this server provide historical listing data?
Yes, both get_sale_listings and get_rental_listings allow you to query historical data by setting the status parameter to 'Inactive' or filtering by date ranges.
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.
