Perplexity

Settle Transactions with PTAX Data

Financial agents disagree on settlement amounts when using different data sources. You inject the MCP Server into their tool list so they all reference the official Brazilian Central Bank PTAX rate. An auditing agent calls `get_cotacao_dolar` to fetch the exact buy and sell values for the invoice date. A separate accounting agent verifies those numbers against internal records. They debate any discrepancies before finalizing the transaction.

AutoGen Agents Debate FX Conversions

Cross-border trade requires accurate multi-currency conversions. One agent executes `listar_moedas` to confirm the target currency code exists in the 150 supported options. Another agent takes that code and runs `get_cotacao_moeda` to pull the specific daily rate. If the spread between buy and sell is unusually high, a risk-management agent flags the transaction for human review.

Analyze BRL Volatility via MCP Server

Forecasting Brazilian Real movements requires deep historical context. Your data-gathering agent calls `get_dolar_periodo` to pull up to a year of PTAX bulletins. It passes the MM-DD-YYYY formatted data directly into the chat. A quantitative analysis agent reviews this timeline alongside data from `get_dolar_sgs`. They deliberate over whether the commercial dollar trend or the official PTAX reference rate provides a better baseline for the upcoming quarter.

Prerequisites

Python 3.10+ installed
autogen-ext[mcp] + autogen-agentchat
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Same packages as above. McpWorkbench is ideal when your agent needs stateful sessions across multiple tool calls.
2

Use McpWorkbench as context manager
Wrap your agent in async with McpWorkbench(...) to maintain shared state and resources. The workbench manages the full MCP session lifecycle.
3

Run with workbench
Pass workbench=workbench to your agent. State is preserved across multiple tool calls within the same session.

agent.py

from autogen_ext.tools.mcp import McpWorkbench, SseServerParams
from autogen_agentchat.agents import AssistantAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient

server_params = SseServerParams(
    url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)

async with McpWorkbench(server_params) as workbench:
    agent = AssistantAgent(
        name="BCB Câmbio — Dólar PTAX, Euro e 150+ Moedas_assistant",
        model_client=OpenAIChatCompletionClient(model="gpt-4o"),
        workbench=workbench,
    )

    result = await agent.run("List recent BCB Câmbio — Dólar PTAX, Euro e 150+ Moedas data")
    print(result.messages[-1].content)
