What is the CNJ Datajud API?

It is the official public API from the Brazilian National Council of Justice that provides access to judicial metadata and process history.

Which AI clients can use this MCP?

You can use this MCP with any compatible client, including Claude, Cursor, Windsurf, and VS Code.

Do I need my own API key?

Yes, you will need to enter your CNJ Datajud API Key to authenticate your requests.

Can I perform complex searches?

Yes, the MCP includes a capability for executing advanced Elasticsearch queries against the database.

Does this cover all Brazilian courts?

It provides access to various courts, including TRFs, TJs, and TST, via their respective API aliases.

How do I find a process if I only have the CNJ number?

Use the search_process_by_number capability. You will need the unformatted digits of the process and the specific court alias (e.g., api_publica_tjsp for São Paulo State Court).

Can I list multiple processes from a specific court organ?

Yes, use search_processes_by_class_and_organ. Provide the court alias, the procedural class code, and the organ code. You can also control the result size and use pagination.

What is the 'Advanced Search' capability for?

The search_processes_advanced capability allows you to send a raw Elasticsearch query body. This is useful for complex filtering that isn't covered by standard search capabilities, such as filtering by specific dates or nested metadata.

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Automate a task

Put CNJ Datajud to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

CNJ Datajud works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put CNJ Datajud to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of CNJ Datajud, so you can see the experience inside your AI.

It does not authenticate your account with CNJ Datajud. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.
