Run multi-agent legal debates with AutoGen

`search_legal_cases` provides the raw court records that initiate multi-agent debates within your AutoGen workspace using this MCP Server. One agent searches for relevant legal precedents, while a second agent calls `get_case_details` to scrutinize the specific rulings and challenge the first agent's legal strategy. This consensus-driven approach ensures that your legal conclusions are thoroughly vetted before they reach your desk. By dividing the labor, your AutoGen agents can systematically cross-reference multiple legal cases without getting bogged down in single-agent context limits.

Conflict resolution in corporate dossiers

`get_company_dossier` pulls complete corporate structures, financial details, and executive lists for your AutoGen agents to analyze. A dedicated risk agent can review the dossier for regulatory red flags, while a financial agent evaluates the company's market position, debating their findings in a shared chat thread. To resolve discrepancies, the agents use `search_companies` to verify corporate names and registration details. This collaborative workflow prevents single-agent bias, ensuring that your corporate intelligence reports are based on a balanced, multi-perspective analysis of the data.

Collaborative press and news analysis

`search_news` feeds real-time press coverage directly into your AutoGen multi-agent workflows for collaborative risk assessment using this MCP integration. A media monitoring agent pulls the latest news articles, while an investigative agent uses `search_biographies` to verify the professional backgrounds of the executives mentioned in the press. Before finalizing their report, the agents consult `list_sources` to rank the credibility of the news outlets. This cooperative process ensures that your team receives synthesized, verified intelligence rather than knee-jerk reactions to uncorroborated media reports.

Setup guide

Set up LexisNexis 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 LexisNexis 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="LexisNexis_assistant",
    model_client=OpenAIChatCompletionClient(model="gpt-4o"),
    tools=tools,
)

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

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