How to Use the Pappers MCP in AutoGen

Q: How do I register Pappers tools with AutoGen agents?

You use the mcpservertools helper with your Vinkius HTTP URL to fetch the tools. Pass this list to your AutoGen AssistantAgent constructor, and the MCP adapter will handle all schema translations automatically.

Q: How does AutoGen handle complex Pappers financial data?

The framework passes raw JSON from getcompanyfinancials to your specialized AutoGen agents. Your financial analyst agent can then parse this data and debate its meaning with your risk assessment agent.

Q: Is my French corporate due diligence data safe when using Pappers with AutoGen?

Absolutely. Every query sent to searchcompanyofficers or getcompanydocument goes through this MCP Server's secure, single-use V8 sandbox. Your proprietary search lists and target company names are never logged or stored.

Let specialized AutoGen agents debate and verify French corporate records using the Pappers MCP Server.

Run multi-agent corporate audits in AutoGen

Running `get_french_company_details` inside AutoGen lets your compliance agents verify corporate structures autonomously. French corporate compliance is too risky to leave to a single AutoGen agent. One AutoGen agent can pull the basic Pappers registry data, while the other runs `get_company_financials` to check for red flags. They debate the Pappers findings in a shared chat, ensuring no weird French corporate structures slip past your compliance team.

Resolve ownership disputes with AutoGen and Pappers

Calling `search_ultimate_beneficial_owners` lets your AutoGen compliance agent find the true owners of a business. Unmasking French shell companies in AutoGen requires looking at multiple data points. If the two AutoGen agents find a mismatch between the declared owners and the legal filings, they flag it for human review. This automated AutoGen debate ensures your Pappers KYC checks are thorough and legally sound.

Monitor French corporate registries autonomously

Monitoring French registries is handled by your AutoGen agents calling `list_monitored_companies` and `list_bodacc_publications`. Set up a dedicated AutoGen agent to monitor corporate registries while you sleep. When a new event is published, the monitoring agent alerts your main AutoGen compliance agent to analyze the impact. This team of AutoGen agents keeps your Pappers corporate intelligence up to date without constant manual searches.

Setup guide

Set up Pappers 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 Pappers 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="Pappers_assistant",
    model_client=OpenAIChatCompletionClient(model="gpt-4o"),
    tools=tools,
)

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

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