Google ADK agent registry lookups

Query French business entities using `search_french_companies` and pipe the output into your Gemini long-context window. It allows your agents to reason over complex corporate hierarchies found in the registry. Use `get_establishment_details` to get precise location data for your Google Cloud infrastructure mapping. It builds a bridge between physical office locations and your digital agent logic.

Monitoring publications via Google ADK

Automate your watchlists by calling `list_monitored_companies` and `list_bodacc_publications`. It keeps your agent updated on legal filings without requiring manual refresh cycles. You can set tool filters to limit access to specific functions within your agent. This keeps your Google ADK implementation clean and focused on the data that matters for your specific use case.

Officer research and UBO identification

Identify directors and managers with `search_company_officers` to build out your entity maps. It maps the people behind the companies directly into your agent's reasoning process. Running `search_ultimate_beneficial_owners` provides the transparency needed for enterprise compliance. Your Google ADK agent gets the facts directly from official filings, reducing the reliance on third-party scrapers.

Setup guide

Set up Pappers 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 Pappers 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="Pappers_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Pappers tools via MCP.",
    tools=mcp_tools,
)
