How to Use the NFe.io MCP in Google ADK

Q: How do I add NFe.io to my Google ADK agent?

Initialize an McpToolset with the server URL and include it in your LlmAgent tools parameter. This allows your agent to call NFe.io functions directly.

Q: Does NFe.io support Google ADK for invoice issuance?

Yes, the server exposes issueserviceinvoice and issuemerchandiseinvoice as native tools. Your agent can invoke these whenever a tax event is required.

Q: Can I filter NFe.io tools in Google ADK?

You can use the toolnames filter to restrict which NFe.io functions your agent can access. This gives you control over the agent's capabilities.

Bring Brazilian tax compliance into your Google ADK agent pipelines with native tool support.

Deploy NFe.io tools within Google ADK

Integrate `issue_service_invoice` and `issue_merchandise_invoice` into your Gemini-powered agent. Your agent can now generate tax documents using real-time data. This setup bridges the gap between your cloud data and tax compliance. It lets your agent execute complex invoicing tasks independently.

Manage company issuers via Google ADK

Call `create_company` to register new issuers through your agent. Your agent can handle onboarding tasks without switching to a dashboard. `list_companies` provides the agent with a list of all current issuers. It allows for dynamic selection based on the specific tax requirements.

Monitor tax operations in Google ADK

Use `get_service_invoice` to query specific tax document records. Your agent can pull details to verify invoice status against your BigQuery datasets. `list_webhooks` lets the agent confirm that your NFe.io integration is correctly configured. It provides an immediate check on your reporting infrastructure.

Setup guide

Set up NFe.io MCP in Google ADK

Prerequisites

Python 3.10+ installed
google-adk package (pip install google-adk)
Active Vinkius subscription with a valid endpoint token

1

Install Google ADK

Run pip install google-adk to install the Agent Development Kit. MCP support is included via the McpToolset class.
2

Connect via SSE transport

Use McpToolset.from_server() with SseServerParams pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create an LlmAgent

Pass the returned mcp_tools list directly to LlmAgent(tools=mcp_tools). The ADK maps each MCP tool to a native Gemini function call — no manual schema definitions required.
4

Run with any Gemini model

The agent works with any Gemini model (gemini-2.0-flash, gemini-2.5-pro, etc.). Copy the full example on the right to get started with NFe.io tools in your ADK agent.

agent.py

from google.adk.agents import LlmAgent
from google.adk.tools.mcp_tool.mcp_toolset import McpToolset
from google.adk.tools.mcp_tool.mcp_session_manager import SseServerParams

# Connect to the MCP via SSE
mcp_tools, exit_stack = await McpToolset.from_server(
    connection_params=SseServerParams(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    )
)

# Create your agent with auto-discovered tools
agent = LlmAgent(
    name="NFe.io_agent",
    model="gemini-2.0-flash",
    instruction="You have access to NFe.io tools via MCP.",
    tools=mcp_tools,
)
