How to Use the Focus Admin MCP in AutoGen

Q: How do I configure AutoGen to use Focus Admin?

Install autogen-extmcp and use mcpservertools with your Vinkius HTTP URL. Pass the resulting tool list directly into your AssistantAgent constructor to give it full fiscal capabilities.

Q: Can an AutoGen agent automatically download DANFE PDFs using Focus Admin?

Yes, the agent can call downloadnfedanfe to fetch the base64-encoded PDF. You can configure a second agent to write this base64 data to your storage system.

Q: How does AutoGen handle errors from the Focus Admin MCP server?

The McpToolAdapter converts API errors into text responses that the agents can read. If a tool like distributedfe fails due to an invalid NSU, the agent can analyze the error and try a different parameter.

Let autonomous AutoGen agents debate and resolve Brazilian fiscal compliance issues using the Focus Admin MCP server.

Let agents debate and issue Correction Letters

The `send_cc_e` tool allows an AutoGen agent to submit correction letters for issued invoices. You can set up a multi-agent system where a compliance agent drafts the correction text, and an auditor agent reviews it before submission. If the auditor agent finds an error, it can trigger `cancel_cc_e` to retract the correction. This collaborative loop ensures that only verified tax modifications reach the Focus NFe API.

Automate invoice numbering management

The `inutilize_numbering` tool voids broken ranges of invoice numbers to keep your tax reporting clean. Your AutoGen agents can monitor invoice generation sequences and automatically detect gaps in numbering so you don't have to. When a gap is found, the agent triggers the voiding tool to notify the tax authority. This setup keeps your business compliant without requiring manual bookkeeping checks.

Multi-agent reconciliation using this MCP Server

The `list_nfe_by_period` tool retrieves all invoices issued within a specific date range. An AutoGen retrieval agent can pull this list and pass it to a processing agent for verification. The processing agent then calls `download_nfe_xml` to inspect individual tax keys. If discrepancies appear, the agents discuss the issue and write a summary report for your finance team.

Setup guide

Set up Focus Admin 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 Focus Admin 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="Focus Admin_assistant",
    model_client=OpenAIChatCompletionClient(model="gpt-4o"),
    tools=tools,
)

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

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

Common questions about Focus Admin MCP in AutoGen

Install `autogen-ext[mcp]` and use `mcp_server_tools` with your Vinkius HTTP URL. Pass the resulting tool list directly into your `AssistantAgent` constructor to give it full fiscal capabilities.

Yes, the agent can call `download_nfe_danfe` to fetch the base64-encoded PDF. You can configure a second agent to write this base64 data to your storage system.

The `McpToolAdapter` converts API errors into text responses that the agents can read. If a tool like `distribute_dfe` fails due to an invalid NSU, the agent can analyze the error and try a different parameter.

Yes, you can run them using either stdio or HTTP transports. Vinkius manages the server hosting, meaning your local AutoGen script only needs a single endpoint token to connect.

Yes, all data transmissions containing invoice details and corporate XMLs are encrypted in transit. Vinkius executes each tool inside a temporary, stateless sandbox that destroys all session data immediately after execution.
