Debate your retirement timeline

Task your agents with using `calculate_milestones` to determine your path to independence. When agents disagree on the timeline, they use the tool to provide empirical evidence for their arguments. You build a system where decisions are based on math, not opinion. The agents negotiate based on the actual output of the calculations, leading to a more grounded final plan.

Negotiate contribution impacts

Have one agent propose a savings rate while another uses `simulate_contribution_impact` to stress-test the suggestion. This forces your agents to reconcile their proposals with mathematical reality. It creates a rigorous environment where ideas are challenged by data. You get a well-vetted plan because the agents are forced to verify their assumptions before presenting a conclusion.

Validate lifestyle expectations

Use `get_lifestyle_targets` as the source of truth for your agents to debate against. One agent can argue for a lower withdrawal rate, while another uses the tool to show the impact on your retirement duration. This conflict-driven approach ensures your financial plan is robust. Your agents iterate until they reach a consensus that balances your desires with the hard numbers.

Setup guide

Set up FIRE Calculator 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 FIRE Calculator 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="FIRE Calculator_assistant",
    model_client=OpenAIChatCompletionClient(model="gpt-4o"),
    tools=tools,
)

result = await agent.run("List recent FIRE Calculator 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="FIRE Calculator_assistant",
        model_client=OpenAIChatCompletionClient(model="gpt-4o"),
        workbench=workbench,
    )

    result = await agent.run("List recent FIRE Calculator data")
    print(result.messages[-1].content)
