Perplexity

Negotiate rates between agents

Let your security agent check the validity of `get_latest_exchange_rates` while your financial agent performs the conversion. They discuss the data before reaching a final answer. This creates a consensus-driven process. If the rates seem off, the agents challenge each other until they agree on the correct values.

Validate currency support

Use `list_supported_currencies` as a gatekeeper tool. One agent verifies the requested currency exists before allowing the conversion agent to proceed. This prevents invalid requests from reaching the main logic. It creates a robust check-and-balance system within your agent group.

Audit historical trends via debate

Task your agents with comparing `get_historical_exchange_rate` data against internal benchmarks. They argue the significance of rate changes to provide a nuanced report. This moves beyond simple data retrieval. The agents provide a conclusion based on their collective analysis of the historical records.

Setup guide

Set up Fixer.io Currency API MCP in AutoGen

Prerequisites

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

1

Install AutoGen with MCP
Run pip install "autogen-ext[mcp]" autogen-agentchat. The MCP extension includes mcp_server_tools for stateless tool access.
2

Fetch tools from the MCP
Call mcp_server_tools(SseServerParams(url=...)) with your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Run your agent
Pass the tools to AssistantAgent and call agent.run(). The agent invokes Fixer.io Currency API tools and returns structured results.

agent.py

from autogen_ext.tools.mcp import SseServerParams, mcp_server_tools
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"
)

tools = await mcp_server_tools(server_params)

agent = AssistantAgent(
    name="Fixer.io Currency API_assistant",
    model_client=OpenAIChatCompletionClient(model="gpt-4o"),
    tools=tools,
)

result = await agent.run("List recent Fixer.io Currency API data")
print(result.messages[-1].content)

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="Fixer.io Currency API_assistant",
        model_client=OpenAIChatCompletionClient(model="gpt-4o"),
        workbench=workbench,
    )

    result = await agent.run("List recent Fixer.io Currency API data")
    print(result.messages[-1].content)

Common questions about Fixer.io Currency API MCP in AutoGen

You provide the tool list to the AssistantAgent constructor. All agents in your group conversation then have access to the functions to coordinate their tasks.

Yes. You can set up one agent to query the data and another to challenge the accuracy. They will iterate until they reach a consensus on the conversion.

Yes. The server supports both stdio and Streamable HTTP, which the AutoGen adapter handles automatically. This keeps the agent communication fast and responsive.

Install the MCP extension and use the server params to initialize the tools. Pass these to your agents, and they will use them as needed during the conversation.

Your agent debate logs contain only the API responses for currency conversion. No persistent storage of these queries occurs, and the server operates in an ephemeral sandbox.
