Targeted case lookups in AutoGen

Your agents can pull specific case details using `search_process_by_number`. It grabs the exact filing status you need to move the conversation forward. Stop guessing about case numbers. Just hand the identifier to your agent and let it parse the return data.

Run complex queries with this MCP Server

Feed raw Elasticsearch queries into `search_processes_advanced` to filter through the Datajud database. This lets your AutoGen agents handle granular data requests that simple searches miss. It treats the court API like a local database. Your agents construct the filter and get the results instantly.

Filter by class and organ for your AutoGen agents

Use `search_processes_by_class_and_organ` to narrow down massive datasets by specific court branches. It helps your agents group cases by category without manual intervention. This tool clears the noise. Your agents only see the relevant procedural classes.

Setup guide

Set up CNJ (Datajud API Pública) 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 CNJ (Datajud API Pública) 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="CNJ (Datajud API Pública)_assistant",
    model_client=OpenAIChatCompletionClient(model="gpt-4o"),
    tools=tools,
)

result = await agent.run("List recent CNJ (Datajud API Pública) 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="CNJ (Datajud API Pública)_assistant",
        model_client=OpenAIChatCompletionClient(model="gpt-4o"),
        workbench=workbench,
    )

    result = await agent.run("List recent CNJ (Datajud API Pública) data")
    print(result.messages[-1].content)

Common questions about CNJ (Datajud API Pública) MCP in AutoGen

You pass the tools directly to your AssistantAgent constructor. AutoGen then decides when to call the API based on the context of the current debate between your agents.

Absolutely. When your agents are debating a case status, they can invoke these tools to verify facts before committing to a final decision.

Yes. Since the McpToolAdapter handles the schema conversion, you can inject these tools into any agent within your existing AutoGen workflow.

Vinkius handles the auth layer for you. You just provide the endpoint token and your agents can start querying right away.

We use an ephemeral V8 Isolate sandbox to isolate your execution environment. The server only touches public judicial case records and procedural metadata, ensuring no private user information ever leaves your local context.
