Resolve pricing debates with AutoGen agents

The `validate_freelancer_budget` tool serves as the ultimate arbiter when your AutoGen agents debate project pricing. One agent might push for a competitive market rate, while another demands a higher margin to cover taxes and insurance. This tool delivers a mathematically proven verdict, forcing both agents to agree on an hourly rate that actually covers the freelancer's cost of living. By injecting this tool into your multi-agent conversations, you eliminate unrealistic assumptions about billable hours. The agents must work with a realistic 65% utilization rate, ensuring their final consensus is based on real-world constraints rather than theoretical 40-hour workweeks.

Analyze overhead and cash flow via multi-agent debate

Use the `validate_freelancer_budget` tool to let your agents stress-test a freelancer's cash flow against payment delays and seasonal gaps. An agent representing the business operations can highlight that 42% of invoices are paid late, demanding a 45-day cash buffer. The tool calculates the exact impact of these delays on net take-home pay, grounding the debate in hard data. This MCP server integration allows your agents to factor in self-employment taxes, health insurance, and software costs automatically. The agents can run multiple scenarios to see how different overhead levels alter the minimum viable hourly rate.

Connect this MCP Server to defend profit margins

The `validate_freelancer_budget` tool helps your AutoGen agents identify and mitigate the cost of scope creep. When a client agent requests extra revisions, your budget agent can run the calculations to show how unpaid work drops the effective hourly rate. This immediate feedback loop ensures your agents never agree to terms that result in a loss. Setting up this MCP server is straightforward with the AutoGen extension package. The adapter handles schema conversion automatically, allowing your agents to call the tool over secure HTTP or stdio transports during their collaborative planning sessions.

Setup guide

Set up Freelancer Budget Prover 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 Freelancer Budget Prover 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="Freelancer Budget Prover_assistant",
    model_client=OpenAIChatCompletionClient(model="gpt-4o"),
    tools=tools,
)

result = await agent.run("List recent Freelancer Budget Prover 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="Freelancer Budget Prover_assistant",
        model_client=OpenAIChatCompletionClient(model="gpt-4o"),
        workbench=workbench,
    )

    result = await agent.run("List recent Freelancer Budget Prover data")
    print(result.messages[-1].content)
