Frequently asked questions
What is the difference between Selic and CDI?
Selic is the overnight rate for government bond-backed interbank loans, set/targeted by the COPOM. CDI is the interbank rate for unsecured overnight deposits between banks. CDI closely tracks Selic and is the most common benchmark for fixed-income investments in Brazil.
Can I trust the Selic Daily effective values?
Yes. The module pipes data strictly authenticated by the Brazilian Central Bank. The effective Selic updates are legally suitable for debt recalculations and financial modeling.
Does it include expected adjustments set by COPOM?
Absolutely. By integrating the Focus expectations array, your AI is acutely aware of forward market opinions preceding actual COPOM rate cut decisions.
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.
