Frequently asked questions
Can my AI compare mortgage rates across lenders?
Yes. Use compare_rates with a program ID to see side-by-side rate comparisons from all available lenders.
How do I track rate trends over time?
Use get_trends with the number of days to analyze. The agent returns historical rate data with daily changes.
Can I see details of a specific loan program?
Yes. Use get_program with the program ID. The agent returns eligibility criteria, rate tiers, and lending guidelines.
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.
