How to Use the VATNode MCP in AutoGen

Q: How does VATNode help AutoGen with multi-country tax analysis?

You let the agents debate. One can call getcountryvatrates for France, while another calls it for Germany. The system converges on a final list of rates after discussing jurisdictional requirements.

Q: Can I get API usage data using VATNode with AutoGen?

Sure thing. An agent can check getapiusage early in the conversation to ensure there's enough quota before starting a multi-round debate on tax law.

Perplexity

Debate tax compliance using the MCP Server.

In an AutoGen system, you can set up agents to debate tax rules. One agent might call `get_country_tax_info` for a specific country while another checks `list_all_vat_rates`. They negotiate which rates are applicable. This consensus-driven approach is better than simple sequential calls because the agents challenge each other's findings until they agree on the correct tax structure.

Validate VAT numbers through multi-agent discussion.

You can build a 'Validator Agent' that uses `validate_vat_number` to check metadata. A second 'Risk Agent' then reviews the output for potential flags using its own logic, simulating a true audit process. This requires deliberation between competing perspectives—the system doesn't just run one tool; it runs several and synthesizes the result.

Compare company data across multiple sources.

The agents can compare results. For example, Agent A gets a company record using `get_company_by_vat`, while Agent B uses `get_country_tax_info` to get the local tax rules for that country. The final decision agent then combines these two distinct data points into one actionable report.

Setup guide

Set up VATNode 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 VATNode 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="VATNode_assistant",
    model_client=OpenAIChatCompletionClient(model="gpt-4o"),
    tools=tools,
)

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

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

Common questions about VATNode MCP in AutoGen

You let the agents debate. One can call `get_country_vat_rates` for France, while another calls it for Germany. The system converges on a final list of rates after discussing jurisdictional requirements.

Yes. You can set up agents to debate the validity of a number. They might call `validate_vat_number` first, and then argue about whether the resulting company metadata is sufficient for compliance.

The server touches company metadata and tax rates. This structured data provides concrete facts that opposing agents can use to challenge or support a conclusion, leading to robust final decisions.

It’s built for it. The tools provide specific inputs (like country codes) and outputs that agents can use as evidence in their conversations, making the process transparent.

Sure thing. An agent can check `get_api_usage` early in the conversation to ensure there's enough quota before starting a multi-round debate on tax law.
