Negotiate travel budgets through agent debate

Let your agents argue over travel costs by using `get_conus_lodging` as the source of truth. One agent proposes a budget, while another checks it against federal limits. This debate ensures your final decision adheres to government standards. If the proposed lodging exceeds the limit, the agents use `get_rates_by_city` to find a compliant alternative.

Multi-agent validation of travel claims

Assign an auditor agent to verify claims using `get_rates_by_zip`. It challenges the traveler agent if the requested reimbursement contradicts the official data. This internal friction prevents errors before they reach your finance department. The agents reach a consensus only when the math matches the data returned by the server.

Automate regional rate comparisons

Use multiple agents to analyze rates across different jurisdictions. One agent calls `get_rates_by_state` to map out regional cost variations for a multi-city trip. This comparative data informs your strategy. By comparing figures from different ZIPs, your team builds a cost-effective travel plan that stays within federal constraints.

Setup guide

Set up GSA Per Diem Rates 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 GSA Per Diem Rates 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="GSA Per Diem Rates_assistant",
    model_client=OpenAIChatCompletionClient(model="gpt-4o"),
    tools=tools,
)

result = await agent.run("List recent GSA Per Diem Rates 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="GSA Per Diem Rates_assistant",
        model_client=OpenAIChatCompletionClient(model="gpt-4o"),
        workbench=workbench,
    )

    result = await agent.run("List recent GSA Per Diem Rates data")
    print(result.messages[-1].content)

Common questions about GSA Per Diem Rates MCP in AutoGen

The agents share the tool outputs within their conversation history. Once one agent retrieves the rate, the others use that information to form their consensus.

The agents treat the tool output as the primary source of truth. They use the data to validate travel requests, not to debate the rates themselves.

Any number of agents in your AutoGen group can access the tools. You simply provide the tool list to each agent that requires financial data.

The server uses a secure, ephemeral connection. Only the specific travel data you request is processed, with no persistent logs of your queries.

The agents should be instructed to trust the latest tool output. You can implement a supervisor agent to resolve any discrepancies using the most recent data.
